There are other parameters that contribute to the performance of the actual system. This specification tries to define the bare drive characteristics, not system throughput, which depends on the system and the application. The following table gives a typical value for each parameter. The detailed descriptions are found in Section 5.0, “Data integrity” beginning on page 21.

Max Maximum value measured on any one drive over the full range of the environmental and voltage conditions. (See Section 6.1, “Environment” on page 25 and Section 6.2, “DC power require- ments” on page 27 for ranges.) The seek time is measured from the start of the actuator’s motion to the start of a reliable read or write operation. A reliable read or write implies that error correction or recovery is not used to correct arrival problems. The average seek time is measured as the weighted average of all possible seek combinations. max Σ (m10 n)(Tnin + Tnout) n=1 Weighted Average = –––––––––––––––––––––––––––– (max + 1)(max) where max = Maximum seek length n = Seek length (1 to max) Tnin = Inward measured seek time for an n track seek Tnout = Outward measured seek time for an n track seek 4.4.2.2 Full stroke seek time Table 6: Full stroke seek time Command type Typical (ms) Max (ms) Read 23.0 30.0 Write 24.0 31.0 Full stroke seek is measured as the average of 1,000 full stroke seeks. 4.4.2.3 Single track seek time (without command overhead, including settling) Table 7: Single track seek time Command type Typical (ms) Max (ms) Read 2.5 4.0 Write 3.0 4.5 Single track seek is measured as the average of one (1) single track seek from every track in both directions (inward and outward).

Spin-up Seek operation mode Seek Write operation mode Write Read operation mode Read The device is capable of responding immediately to idle media access requests. All Performance Idle electronic components remain powered and the full frequency servo remains opera- tional. The device is capable of responding immediately to media access requests. Some cir- cuitry—including servo system and R/W electronics—is in power saving mode. The Active idle head is parked near the mid-diameter the disk without servoing. A device in Active idle mode may take longer to complete the execution of a command because it must activate that circuitry. The head is unloaded onto the ramp position. The spindle motor is rotating at full Low power idle speed. Travelstar 80GN Hard Disk Drive Specification 19 Table 10: Description of operating modes Operating mode Description The device interface is capable of accepting commands. The spindle motor is stopped. Standby All circuitry but the host interface is in power saving mode. The spindle motor is stopped. All circuitry but the host interface is in power saving mode. The device requires a soft reset or a hard reset to be activated. All electronics, includ- Sleep ing spindle motor and host interface, are shut off. 4.4.3.2 Mode transition time - from Standby to Idle Table 11: Drive ready time Transition Time Transition Time From To (typical) (max.) Standby Idle 2.0 (80,60GB) 9.5 1.8(40,30,20GB) 4.4.3.3 Operating mode at power on The device goes into Idle mode after power on or hard reset as an initial state. Initial state may be changed to Standby mode using pin C on the interface connector. Refer to section 7.10, “Drive address setting” on page 55 for details. 4.4.3.4 Adaptive power save control The transient timing from Performance Idle mode to Active Idle mode and Active Idle mode to Low Power Idle mode is controlled adaptively according to the access pattern of the host system. The transient timing from Low Power Idle mode to Standby mode is also controlled adaptively, if it is allowed by Set Features Enable Adavanced Power Management subcommand. Travelstar 80GN Hard Disk Drive Specification 20 5.0 Data integrity 5.1 Data loss at power off Data loss will not be caused by a power off during any operation except the write operation. A power off during a write operation causes the loss of any received or resident data that has not been writ- ten onto the disk media. A power off during a write operation might make a maximum of one sector of data unreadable. This state can be recovered by a rewrite operation. 5.2 Write Cache When the write cache is enabled, the write command may complete before the actual disk write operation finishes. This means that a power off, even after the write command completion, could cause the loss of data that the drive has received but not yet written onto the disk. In order to prevent this data loss, confirm the completion of the actual write operation prior to the power off by issuing a • Soft reset • Hard reset • Flush Cache command • Standby command • Standby Immediate command • Sleep command Confirm the command's completion. 5.3 Equipment status The equipment status is available to the host system whenever the drive is not ready to read, write, or seek. This status normally exists at power-on time and will be maintained until the following conditions are sat- isfied: • Access recalibration/tuning is complete • Spindle speed meets requirements for reliable operations • Self-check of drive is complete Appropriate error status is made available to the host system if any of the following conditions occur after the drive has become ready: • Spindle speed lies outside the requirements for reliable operation • The occurrence of a Write Fault condition Travelstar 80GN Hard Disk Drive Specification 21 5.4 WRITE safety The drive ensures that the data is written into the disk media properly. The following conditions are moni- tored during a write operation. When one of these conditions exceeds the criteria, the write operation is ter- minated and the automatic retry sequence is invoked. • Head off track • External shock • Low supply voltage • Spindle speed out of tolerance • Head open/short 5.5 Data buffer test The data buffer is tested at power on reset and when a drive self-test is requested by the host. The test con- sists of a write/read '00'x and 'ff'x pattern on all buffers. 5.6 Error recovery Errors occurring on the drive are handled by the error recovery procedure. Errors that are uncorrectable after application of the error recovery procedures are reported to the host sys- tem as non-recoverable errors. 5.7 Automatic reallocation The sectors that show some errors may be reallocated automatically when specific conditions are met. The drive does not report any auto reallocation to the host system. The conditions for auto reallocation are described below. 5.7.1 Nonrecovered write errors When a write operation cannot be completed after the Error Recovery Procedure (ERP) is fully carried out, the sectors are reallocated to the spare location. An error is reported to the host system only when the write cache is disabled and the auto reallocation has failed. 5.7.2 Nonrecoverable read error When a read operation fails after ERP is fully carried out, a hard error is reported to the host system. This location is registered internally as a candidate for the reallocation. When a registered location is specified as a target of a write operation, a sequence of media verification is performed automatically. When the result of this verification meets the required criteria, this sector is reallocated. 5.7.3 Recovered read errors When a read operation for a sector fails and is recovered at the specific ERP step, the sector is reallocated automatically. A media verification sequence may be run prior to the reallocation according to the pre- defined conditions. Travelstar 80GN Hard Disk Drive Specification 22 5.8 ECC The 52 byte four way interleaved ECC processor provides user data verification and correction capability. The first 4 bytes of ECC are check bytes for user data and the other 48 bytes are Read Solomon ECC. Each interleave has 12 bytes for ECC. Hardware logic corrects up to 20 bytes (5 bytes for each interleave) errors on-the-fly. Following are some examples of error cases. An "O" means that the byte contains no error. An "X" means that at least one bit of the byte is bad. Table 12: Examples of error cases.

Service life of the drive is approximately 5 years or 20,000 power on hours, which comes first, under the following assumptions: • Less than 333 power on hours per month. • Seeking/Writing/Reading operation is less than 20% of power on hours. This does not represent any warranty or warranty period. Applicable warranty and warranty period are covered by the purchase agreement. 6.3.5 Preventive maintenance None 6.3.6 Load/unload The product supports a minimum of 300,000 normal load/unloads. Load/unload is a functional mechanism of the hard disk drive. It is controlled by the drive micro code. Specifically, unloading of the heads is invoked by the following commands: • Hard reset • Standby • Standby immediate • Sleep Load/unload is also invoked as one of the idle modes of the drive. The specified start/stop life of the product assumes that load/unload is operated normally, not in emergency mode. 6.3.6.1 Emergency unload When hard disk drive power is interrupted while the heads are still loaded the micro code cannot operate and the normal 5-volt power is unavailable to unload the heads. In this case, normal unload is not possible. The heads are Travelstar 80GN Hard Disk Drive Specification 29 unloaded by routing the back EMF of the spinning motor to the voice coil. The actuator velocity is greater than the normal case and the unload process is inherently less controllable without a normal seek current profile. Emergency unload is intended to be invoked in rare situations. Because this operation is inherently uncontrolled, it is more mechanically stressful than a normal unload. The drive supports a minimum of 20,000 emergency unloads. 6.3.6.2 Required Power-Off Sequence The required BIOS sequence for removing power from the drive is as follows: Step 1: Issue one of the following command: • Standby • Standby immediate • Sleep Note: Do not use the Flush Cache command for the power off sequence because this command does not invoke Unload. Step 2: Wait until the Command Complete status is returned In a typical case 350 ms are required for the command to finish completion; however, the BIOS time out value needs to be 30 seconds considering error recovery time. Refer to Section 14.0, “Time-out values” on page 193. Step 3: Terminate power to the drive This power-down sequence should be followed for entry into any system power-down state, system suspend state, or system hibernation state. In a robustly designed system, emergency unload is limited to rare scenarios, such as battery removal during operation. 6.3.6.3 Power Switch design considerations In systems that use this drive consideration should be given to the design of the system power switch. Hitachi recommends that the switch operate under control of the BIOS rather than be hardwired. The same recom- mendation is made for cover-close switches. When a hardwired switch is turned off, emergency unload occurs, as well as the problems cited in Section 5.1, “Data loss at power off” on page 21 and Section 5.2, “Write Cache” on page 21. 6.3.6.4 Test considerations Start/stop testing is classically performed to verify head/disk durability. The heads do not land on the disk, there- fore this type of test should be viewed as a test of the load/unload function. Start/Stop testing should be done by commands through the interface, not by power cycling the drive. Simple power cycling of the drive invokes the emergency unload mechanism and subjects the HDD to nontypical mechan- ical stress. Power cycling testing may be required to test the boot-up function of the system. In this case Hitachi recommends that the power-off portion of the cycle contain the sequence specified in Section 6.3.6.2, “Required Power-Off Sequence” on page 30. If this is not done, the emergency unload function is invoked and nontypical stress results.

Figure 2: Mounting hole locations 6.4.3 Connector and jumper description A jumper is used to designate the drive address as either master or slave. The jumper setting method is described in Section 7.10, “Drive address setting” on page 55. Connector specifications are included in Section 7.2, “Interface connector” on page 39. Travelstar 80GN Hard Disk Drive Specification 32 6.4.4 Mounting orientation The drive will operate in all axes (six directions) and will stay within the specified error rates when tilted ±5degrees from these positions. Performance and error rate will stay within specification limits if the drive is operated in the other permissible ori- entations from which it was formatted. Thus a drive formatted in a horizontal orientation will be able to run verti- cally and vice versa. The recommended mounting screw torque is 3.0±0.5 kgf-cm. The recommended mounting screw depth is 3.0±0.3 mm for bottom and 3.5±0.5 mm for horizontal mounting. The user is responsible for using the appropriate screws or equivalent mounting hardware to mount the drive securely enough to prevent excessive motion or vibration of the drive at seek operation or spindle rotation. 6.4.5 Load/unload mechanism The head load/unload mechanism is provided to protect the disk data during shipping, movement, or storage. Upon power down, a head unload mechanism secures the heads at the unload position. See Section 6.5.4, “Nonoperating shock” on page 35 for additional details. 6.5 Vibration and shock All vibration and shock measurements in this section are for drives without mounting attachments for systems. The input level shall be applied to the normal drive mounting points.Vibration tests and shock tests are to be conducted by mounting the drive to a table using the bottom four mounting holes. 6.5.1 Operating vibration The drive will operate without a hard error while being subjected to the following vibration levels. 6.5.1.1 Random vibration The test consists of 30 minutes of random vibration using the power spectral density (PSD) levels below.

Table 22: Nonoperating shock Duration of 1 ms Duration of 11 ms 7840 m/sec2 (800 G) 1176 m/sec2 (120 G) The shocks are applied for each direction of the drive for three mutually perpendicular axes, one axis at a time. Input levels are measured on a base plate where the drive is attached with four screws 6.6 Acoustics 6.6.1 Sound power levels The criteria of A-weighted sound power level are described below. Measurements are to be taken in accordance with ISO 7779. The mean of the sample of 40 drives is to be less than the typical value. Each drive is to be less than the maximum value. The drives are to meet this requirement in both board down orientations. Table 23: Weighted sound power A-weighted sound power Typical (Bels) Maximum (Bels) Idle 2.0 2.3 40GB, 30GB, 20GB models Operating 2.4 2.6 Idle 2.3 2.6 80GB, 60GB models Operating 2.7 2.9 The background power levels of the acoustic test chamber for each octave band are to be recorded. Sound power tests are to be conducted with the drive supported by spacers so that the lower surface of the drive be located 25±3 mm above from the chamber floor. No sound absorbing material shall be used. The acoustical characteristics of the disk drive are measured under the following conditions: Mode definitions • Idle mode: Power on, disks spinning, track following, unit ready to receive and respond to control line com- mands. • Operating mode: Continuous random cylinder selection and seek operation of the actuator with a dwell time at each cylinder. The seek rate for the drive is calculated with the following formula: Ns= 0.4/(Tt + T1) where: Ns = average seek rate in seeks/s Travelstar 80GN Hard Disk Drive Specification 35 Tt = published seek time from one random track to another without including rotational latency T1= equivalent time in seconds for the drive to rotate by half a revolution 6.6.2 Discrete tone penalty Discrete tone penalties are added to the A-weighted sound power (Lw) with the following formula only when determining compliance. Lwt(spec) = Lw = 0.1Pt + 0.3 < 4.0 (Bels) where Lw = A-weighted sound power level Pt = Value of desecrate tone penalty = dLt – 6.0(dBA) dLt = Tone-to-noise ratio taken in accordance with ISO 7779 at each octave band 6.7 Identification labels The following labels are affixed to every drive: • A label which is placed on the top of the head disk assembly containing the statement "Made by Hitachi" or equivalent, part number, EC number, and FRU number. • A bar code label which is placed on the disk drive based on user request. The location on the disk drive is to be designated in the drawing provided by the user. • Labels containing the vendor's name, disk drive model number, serial number, place of manufacture, and UL/ CSA logos. • Labels containing jumper information if required by the customer. 6.8 Electromagnetic compatibility When installed in a suitable enclosure and exercised with a random accessing routine at maximum data rate meets the worldwide EMC requirements listed below: • United States Federal Communications Commission (FCC) Rules and Regulations (Class B), Part 15 • RFI Japan VCCI, Requirements of IBM products • EU EMC Directive, Technical Requirements and Conformity Assessment Procedures 6.8.1 CE mark The product is certified for compliance with EC directive 89/336/EEC.

These lines change from the conventional to special definitions at the moment the host decides to allow a DMA burst, if the Ultra DMA transfer mode was previously chosen via SetFeatures. The drive becomes aware of this change upon assertion of the DMACK line. These lines revert back to their original definitions upon the deassertion of DMACK- at the termination of the DMA burst.

The lower 8 lines, DD00-07, are used for Regis- ter and ECC access. All 16 lines, DD00–15, are used for data transfer. These are 3-state lines with 16mA current sink capability. DA00–DA02 These are addresses used to select the individual register in the drive. CS0- The chip select signal generated from the Host address bus. When active, one of the Command Block Registers [Data, Error (Features when written), Sector Count, Sector Number, Cylinder Low, Cylinder High, Drive/Head and Status (Command when written) register] can be selected. CS1- The chip select signal generated from the Host address bus. When active, one of the Control Block Registers [Alternate Status (Device Control when written) and Drive Address register] can be selected. RESET- This line is used to reset the drive. It shall be kept at a Low logic state during power up and kept High thereafter. DIOW- The rising edge of this signal holds data from the data bus to a register or data register of the drive. DIOR- When this signal is low, it enables data from a register or data register of the drive onto the data bus. The data on the bus shall be latched on the rising edge of DIOR- INTRQ The interrupt is enabled only when the drive is selected and the host activates the IEN- bit in the Device Control Register. Otherwise, this signal is in high impedance state regardless of the state of the IRQ bit. The interrupt is set when the IRQ bit is set by the drive CPU. The IRQ is reset to zero by a host read of the status register or a write to the Command Register. This signal is a 3-state line with 16mA of sink capability. Travelstar 80GN Hard Disk Drive Specification 41 DASP- This is a time-multiplexed signal which indicates that a drive is active or that device 1 is present. This signal is driven by an Open-Drain driver and internally pulled up to 5.0 volts through a 10 k. resistor. During a Power- On initialization or after RESET- is negated, DASP- shall be asserted by device 1 within 400 ms to indicate that device 1 is present. Device 0 shall allow up to 450 ms for device 1 to assert DASP-. If device 1 is not present, device 0 may assert DASP- to drive an LED indicator on a host. The DASP- signal shall be negated fol- lowing acceptance of the first valid command by device 1. Anytime after negation of DASP-, either drive may assert DASP- to indicate that a drive is active. Caution The host doesshall not drive DASP-. If the host connects to DASP- for any purpose, the host shall ensure that the signal level detected on the interface for DASP- shall maintain VoH and VoL compatibility, given the IoH and IoL requirements of the DASP- device drivers. Caution When DASP- is negated, the line is in a high impedance state. The signal level may look less than 5.0V even though the line is pulled up to 5.0V through a resistor." PDIAG- This signal shall be asserted by device 1 to indicate to device 0 that it has completed the diagnostics. This line is pulled up to 3.3 volts in the drive through a 10 kW resistor. Following a Power On Reset, software reset, or RESET-, drive 1 shall negate PDIAG- within 1 ms (to indicate to device 0 that it is busy). Drive 1 shall then assert PDIAG- within 30 seconds to indicate that it is no longer busy and is able to provide status. Following the receipt of a valid Execute Drive Diagnostics command, device 1 shall negate PDIAG- within 1 ms to indicate to device 0 that it is busy and has not yet passed its drive diagnostics. If device 1 is present then device 0 shall wait up to 6 seconds from the receipt of a valid Execute Drive Diagnostics command for drive 1 to assert PDIAG-. Device 1 should clear BSY before asserting PDIAG-, as PDIAG- is used to indicate that device 1 has passed its diagnostics and is ready to post status. If DASP- was not asserted by device 1 during reset initialization, device 0 shall post its own status immediately after it completes diagnostics and clears the device 1 Status register to 00h. Device 0 may be unable to accept commands until it has finished its reset proce- dure and is ready (DRDY=1). CSEL (Cable Select) This signal is monitored to determine the drive address (master or slave) when the jumper on the interface con- nector is at Position-3. When CSEL is at ground or is at a low level, the drive works as a Master. If CSEL is open or is at a logical high level, the drive works as a Slave. The signal level of CSEL to one drive should be different from the signal level to another drive on the same AT interface cable to avoid master-master or slave-slave configurations. KEY Pin position 20 has no connection pin. It is recommended to close the respective position of the cable connector in order to avoid incorrect insertion. IORDY This signal is an indication to the host that the drive is ready to complete the current I/O cycle. This line is driven low at the falling edge of DIOR- or DIOW- when the drive needs some additional WAIT cycle(s) to Travelstar 80GN Hard Disk Drive Specification 42 extend the PIO cycle. This line can be connected to the host IORDY signal in order to insert a WAIT state(s) into the host PIO cycle. This signal is an Open-Drain output with 16mA sink capability. 5V Power There are two input pins for the +5 V power supply. One is the "+5 V Logic" input pin and the second is the "+5 V Motor" input pin. These two input pins are tied together within the drive. DMACK- This signal shall be used by the host in response to DMARQ to either acknowledge that data has been accepted, or that data is available. This signal is internally pulled up to 5 Volt through a 15kW resistor with a resistor tolerance value of –50% to +100%. DMARQ This signal is used for DMA data transfers between the host and drive. It shall be asserted by the drive when it is ready to transfer data to or from the host. The direction of data transfer is controlled by HIOR- and HIOW- signals. This signal is used in a handshake mode with DMACK-. This signal is a 3-state line with 16mA sink capability and internally pulled down to GND through a 10 kW resistor. HDMARDY- (Ultra DMA) This signal is used only for Ultra DMA data transfers between host and drive. The signal HDMARDY- is a flow control signal for Ultra DMA data in bursts. This signal is held asserted by the host to indicate to the device that the host is ready to receive Ultra DMA data in transfers. The host may negate HDMARDY- to pause an Ultra DMA data in transfer. HSTROBE (Ultra DMA) This signal is used only for Ultra DMA data transfers between host and drive. The signal HSTROBE is the data out strobe signal from the host for an Ultra DMA data out transfer. Both the rising and falling edge of HSTROBE latch the data from DD (15:0) into the device. The host may stop toggling HSTROBE to pause an Ultra DMA data out transfer. STOP (Ultra DMA) This signal is used only for Ultra DMA data transfers between host and drive. The STOP signal shall be asserted by the host prior to initiation of an Ultra DMA burst. A STOP shall be negated by the host before data is transferred in an Ultra DMA burst. Assertion of STOP by the host during or after data transfer in an Ultra DMA mode signals the termination of the burst. DDMARDY- (Ultra DMA) This signal is used only for Ultra DMA data transfers between host and drive. The signal DDMARDY- is a flow control signal for Ultra DMA data out bursts. This signal is held asserted by the device to indicate to the host that the device is ready to receive Ultra DMA data out transfers. The device may negate DDMARDY- to pause an Ultra DMA data out transfer. DSTROBE (Ultra DMA) This signal is used only for Ultra DMA data transfers between host and drive. The signal DSTROBE is the data in strobe signal from the device for an Ultra DMA data in transfer. Both the rising and the falling edge of DSTROBE latch the data from DD (15:0) into the host. The device may stop tog- gling DSTROBE to pause an Ultra DMA data in transfer.

Drive address setting A jumper placed on the interface connector determines the drive address. Three drive addresses are shown below. Two addresses require the setting of a jumper. 31 2 4 3 5 12 4 Figure 3: Drive address setting Setting 1—Device 0 (Master) (no jumper is used) Setting 2—Device 1 (Slave) Setting 3—Cable Select Setting 4—Do not attach a jumper here Setting 5—Do not attach a jumper here The default setting at shipment is Setting 1 (no jumper). When pin C is grounded, the drive does not spin up at POR. When the drive address is Cable Select, the address depends on the condition of pin 28 of the AT interface cable. If pin 28 is ground (or low), the drive is a Master. If pin 28 is open (or logic high), the drive is a Slave. Travelstar 80GN Hard Disk Drive Specification 55 7.11 Addressing of HDD registers The host addresses the drive through a set of registers called a Task File. These registers are mapped into the host's I/O space. Two chip select lines (CS0- and CS1-) and three address lines (DA00–02) are used to select one of these registers, while a DIOR- or DIOW- is provided at the specified time. The chip select line CS0- is used to address the Command Block registers while the CS1- is used to address Con- trol Block registers. The following table shows the I/ O address map.

Interface specification Travelstar 80GN Hard Disk Drive Specification 57 Travelstar 80GN Hard Disk Drive Specification 58 8.0 General 8.1 Introduction This specification describes the host interface of the Travelstar 80GN. The interface conforms to the Working Document of Information technology, AT Attachment with Packet Interface Extension (ATA/ATAPI-6) Revision 2, dated 2 August 2001, with certain limitations described in Section 9.0, “Deviations from standard” on page 61. The drive supports the following functions as Vendor Specific Functions: • Address Offset Feature • Format Unit Function • SENSE CONDITION command 8.2 Terminology Device The Travelstar 80GN drive Host Host indicates the system that the device is attached to. First Command The first command which is executed after the power on reset (also known as a hard reset) is the Standby mode command. INTRQ Interrupt request (Device or Host) Travelstar 80GN Hard Disk Drive Specification 59 Travelstar 80GN Hard Disk Drive Specification 60 9.0 Deviations from standard The device conforms to the referenced specifications, with deviations described below. The interface conforms to the Working Document of Information Technology, AT Attachment with Packet Interface Extension (ATA/ATAPI-6) Revision 3, dated 30 October 2001, with the following deviation: Standby Timer Standby timer is enabled by STANDBY command or IDLE command. The value in the Sector Count register shall be used to determine the time programmed into the Standby timer. If the Sector Count register is zero, the Standby timer is automatically set to 109 minutes. Write Verify WRITE VERIFY command does not include read verification after write operation. The function is the same as WRITE SECTORS command. S.M.A.R.T. Return Status S.M.A.R.T. RETURN STATUS subcommand does not check advisory attributes. This means that the device will not report a threshold exceeded condition unless the prefailure attributes exceed their corresponding thresholds. For example, a Power-On Hours Attribute never results in a negative reliability status.

The Command Block Registers are used for sending commands to the device or posting status from the device. The Control Block Registers are used for device control and to post alternate status. Travelstar 80GN Hard Disk Drive Specification 63 10.1 Alternate Status Register Table 38: Alternate Status Register 76543210 BSY RDY DF DSC DRQ COR IDX ERR This register contains the same information as the Status Register. The only difference between this register and the Status Register is that reading the Alternate Status Register does not imply an interrupt acknowledge or a clear of a pending interrupt. See Section 10.12, "Status Register," on page 67 for the definition of the bits in this register. 10.2 Command Register This register contains the command code being sent to the device. Command execution begins immediately after this register is written. The command set is shown in Table 58: , "Command Set (1 of 2)," on page 97 and Table 59: , "Command Set (2 of 2)," on page 98. All other registers required for the command must be set up before writ- ing to the Command Register. 10.3 Data Register This register is used to transfer data blocks between the device data buffer and the host. It is also the register through which sector information is transferred on a Format Track command and the configuration information is transferred on an Identify Device command. All data transfers are 16 bits wide, except for ECC byte transfers, which are 8 bits wide. Data transfers are PIO only. The register contains valid data only when DRQ = 1 is in the Status Register. Travelstar 80GN Hard Disk Drive Specification 64 10.4 Device Control Register Table 39: Device Control Register 76543210 HOB - - - 1 SRST -IEN 0 Bit Definitions HOB HOB (high order byte) is defined by the 48-bit Address feature set. A write to any Command Register shall clear the HOB bit to zero. SRST Software Reset. The device is held at reset when RST = 1. Setting RST = 0 again enables the device. To ensure that the device recognizes the reset, the host must set RST = 1 and wait for at least 5 ms before setting RST = 0. -IEN Interrupt Enable. When IEN = 0, and the device is selected, the device interrupts to the host will be enabled. When IEN = 1, or the device is not selected, the device interrupts to the host will be disabled. 10.5 Drive Address Register Table 40: Drive Address Register 76543210 HIZ WTG -H3 -H2 -H1 -H0 -DS1 -DS0 This register contains the inverted drive select and head select addresses of the currently selected drive. Bit Definitions HIZ High Impedance. This bit is not a device and will always be in a high impedance state. -WTG Write Gate. This bit is 0 when writing to the disk device is in progress. -H3, -H2,- -H3, -H2,-H1,-H0-Head Select. These four bits are the one's complement of the binary coded H1,-H0- address of the currently selected head. Bit -H0 is the least significant. -DS1 Drive Select 1. The Drive Select bit for device 1 is active low. DS1 = 0 when device 1 (slave) is selected and active. -DS0 Drive Select 0. The Drive Select bit for device 0 is active low. DS0 = 0 when device 0 (master) is selected and active. Travelstar 80GN Hard Disk Drive Specification 65 10.6 Device/Head Register Table 41: Device Head/Register 76543210 1 L 1 DRV HS3 HS2 HS1 HS0 This register contains the device and head numbers. Bit Definitions L Binary encoded address mode select. When L = 0, addressing is by CHS mode. When L = 1, addressing is by LBA mode. DRV Device. When DRV = 0, device 0 (master) is selected. When DRV = 1, device 1 (Slave) is selected. HS3, HS2, Head Select. These four bits indicate the binary encoded address of the head. Bit HS0 is the least HS0 significant bit. At command completion, these bits are updated to reflect the currently selected head. The head number may be from zero to the number of heads minus one. In LBA mode, HS3 through HS0 contain bits 24–27 of the LBA. At command completion, these bits are updated to reflect the current LBA bits 24–27. 10.7 Error Register Table 42: Error Register 765 4 3210 CRC UNC 0 IDNF 0 ABRT TK0NF AMNF This register contains the status from the last command executed by the device or a diagnostic code. At the comple- tion of any command, except Execute Device Diagnostic, the contents of this register are always valid even if ERR = 0 is in the Status Register. Following a power on, a reset, or completion of an Execute Device Diagnostic command, this register contains a diagnostic code. See Table 46: , "Diagnostic codes," on page 70 for the definitions. Bit Definitions ICRCE (CRC) Interface CRC Error. When CRC = 1, it indicates that a CRC error has occurred on the data bus during a Ultra DMA transfer. UNC Uncorrectable Data Error. When UNC = 1 it indicates that an uncorrectable data error has been encountered. IDNF(IDN) ID Not Found. When IDN = 1, it indicates that the requested sector's ID field could not be found. ABRT Aborted Command. When ABT = 1, it indicates that the requested command has been aborted due (ABT) to a device status error or an invalid parameter in an output register. TK0NF (T0N) Track 0 Not Found. When T0N = 1, it indicates that track 0 was not found during a recallibrate command. AMNF Address Mark Not Found. When AMN = 1, it indicates that the data address mark has not been found after finding the correct ID field for the requested sector. Travelstar 80GN Hard Disk Drive Specification 66 10.8 Features Register This register is command specific. This register is used with the Set Features command, the S.M.A.R.T. Function Set command, and the Format Unit command. 10.9 LBA High Register This register is command specific. This is used with the Set Features command, S.M.A.R.T. Function Set com- mand and Format Unit command. When 48-bit addressing commands are used, the "most recently written" content contains LBA Bits 16-23, and the "previous content" contains Bits 40-47. The 48-bit Address feature set is described in Section 11.15, "48-bit Address Feature Set," on page 89. 10.10 LBA Mid Register This register contains Bits 8-15. At the end of the command, this register is updated to reflect the current LBA Bits 8-15. When 48-bit addressing commands are used, the "most recently written" content contains LBA Bits 8-15 and the "previous content" contains Bits 32-39. 10.11 Sector Count Register This register contains the number of sectors of data requested to be transferred on a read or write operation between the host and the device. If the value in the register is set to 0, a count of 256 sectors (in 28-bit addressing) or 65,536 sectors (in 48-bit addressing) is specified. If the register is zero at command completion, the command was successful. If not successfully completed, the reg- ister contains the number of sectors which need to be transferred in order to complete the request. The contents of the register are defined otherwise on some commands. These definitions are given in the command descriptions. 10.12 Status Register Table 43: Status Register 76543210 BSY DRDY DF DSC DRQ COR IDX ERR This register contains the device status. The contents of this register are updated whenever an error occurs and at the completion of each command. If the host reads this register when an interrupt is pending, it is considered to be the interrupt acknowledge. Any pending interrupt is cleared whenever this register is read. If BSY=1, no other bits in the register are valid. Travelstar 80GN Hard Disk Drive Specification 67 Bit Definitions BSY Busy. Bit BSY=1 whenever the device is accessing the registers. The host should not read or write any registers when BSY=1. If the host reads any register when BSY=1, the contents of the Status Register will be returned. DRDY Device Ready. When bit RDY=1 it indicates that the device is capable of responding to a com- (RDY) mand. Bit RDY will be set to 0 during power on until the device is ready to accept a command. DF Device Fault. It DF=1 it indicates that the device has detected a write fault condition. Bit DF is set to 0 after the Status Register is read by the host. DSC Device Seek Complete. If DSC=1, it indicates that a Seek has completed and the device head is settled over a track. Bit DSC is set to 0 by the device just before a Seek begins. When an error occurs, this bit is not changed until the Status Register is read by the host and at that time the bit again indicates the current Seek complete status. When the device enters into or is in Standby mode or Sleep mode, this bit is set by device in spite of the drive not spinning up. DRQ Data Request. Bit DRQ=1 indicates that the device is ready to transfer a word or byte of data between the host and the device. The host should not write the Command register when DRQ=1. CORR Corrected Data. Always 0 IDX IDXIndex. Bit IDX=1 once per revolution. Since IDX=1, only for a very short time during each revolution, the host may not see it set to 1 even if the host is reading the Status Register continu- ously. Therefore the host should not attempt to use IDX bit for timing purposes. ERR Error. Bit ERR=1 indicates that an error occurred during execution of the previous command. The Error Register should be read to determine the error type. The device sets bit ERR=0 when the next command is received from the host. Travelstar 80GN Hard Disk Drive Specification 68 11.0 General 11.1 Reset response ATA has the following three types of resets: The device executes a series of electrical circuitry diagnostics, spins up the Power On Reset (POR) head disk assembly, tests speed and other mechanical parametric, and sets default values. The RESET signal is negated in the ATA Bus. The device resets the interface Hard Reset (Hardware Reset) circuitry and sets the default values. The SRST bit in the Device Control Register is set and then is reset. The device Soft Reset (Software Reset) resets the interface circuitry according to the Set Features requirement. The actions of each reset are shown in the table below. Table 44: Reset response table POR hard reset soft reset -o o Aborting Host interface - (*1) (*1) Aborting Device operation ox x Initialization of hardware ox x Internal diagnostic (*6) x x Starting or Spinning Up spindle motor ooo Initialization of registers (*2) oo x DASP- handshake ooo PDIAG- handshake oo (*3) Reverting programmed parameters to default Number of CHS (set by Initialize Device Parameters) Multiple mode Write Cache Delayed Write Read look-ahead ECC bytes Volatile max. Address Address offset mode (*6) (*4) (*4) Power mode ooo Reset Standby timer value (*5) o – execute x – does not execute Notes: (*1) Execute after the data in write cache has been written. (*2) The default value on POR is shown in Table 45: “Default Register Values” on page 70. (*3) The Set Features command with Feature register = CCh enables the device to revert these parameters to the power on defaults. (*4) In the case of sleep mode, the device goes to standby mode. In other cases, the device does not change current mode. (*5) After reset the Standby timer value is set to 109 minutes. (*6) Set according to the initial power mode selection. Travelstar 80GN Hard Disk Drive Specification 69 11.2 Register initialization After a power on, a hard reset, or a software reset, the register values are initialized as shown in the table below. Table 45: Default Register Values Register Default Value Error Diagnostic Code Sector Count 01h LBA Low 01h LBA Mid 00h LBA High 00h Device A0h Status 50h Alternate Status 50h If an Execute Device Diagnostic command is carried out, if the system is powered on, or if a hard reset occurs, the system generates an Error Register diagnostic code. See the table below for a description of the codes. Table 46: Diagnostic codes Code Description 01h No error detected 02h Formatter device error 03h Sector buffer error 04h ECC circuitry error 05h Controller microprocessor error 8xh Device 1 failed Travelstar 80GN Hard Disk Drive Specification 70 11.3 Diagnostic and Reset considerations The Set Max password, the Set Max security mode and the Set Max unlock counter are not retained over a Power On Reset but are retained over a Hard Reset or Soft Reset. For each Reset and Execute Device Diagnostic, the diagnostic is done as follows: Power On DASP– is read by Device 0 to determine if Device 1 is present. If Device 1 is present, Reset, Hard Device 0 shall read PDIAG– to determine when it is valid to clear the BSY bit and Reset whether Device 1 has powered on or reset without error, otherwise Device 0 clears the BSY bit whenever it is ready to accept commands. Device 0 may assert DASP– to indicate device activity. If Device 1 is not present, Device 0 does not Assert DASP– at POR. Soft Reset If Device 1 is present, Device 0 shall read PDIAG– to determine when it is valid to clear the BSY bit and whether Device 1 has reset without any errors; otherwise, Device 0 shall simply reset and clear the BSY bit. DASP– is asserted by Device 0 (and Device 1 if it is present) in order to indicate device active. Execute Device If Device 1 is present, Device 0 shall read PDIAG– to determine when it is valid to clear Diagnostic the BSY bit and if Device 1 passed or failed the EXECUTE DEVICE DIAGNOSTIC command; otherwise, Device 0 shall simply execute its diagnostics and then clear the BSY bit. DASP– is asserted by Device 0 (and Device 1 if it is present) in order to indicate that the device is active. In each case – Power On Reset [Hard Reset], Soft Reset, and the Execute Device Diagnostic command – the Device 0 Error register value is interpreted using the table below. Table 47: Reset error register values Device 1 present? PDIAG- Asserted? Device 0 Passed Error Register Yes Yes Yes 01h Yes Yes No 0xh Yes No Yes 81h Yes No No 8xh No (not read) Yes 01h No (not read) No 0xh The "x" indicates the appropriate Diagnostic Code for the Power on, RESET-, Soft Reset, or Device Diagnostic error. Travelstar 80GN Hard Disk Drive Specification 71 11.4 Power-off considerations 11.4.1 Load/Unload Load/Unload is a functional mechanism of the hard disk drive. It is controlled by the drive microcode. Specifically, unloading of the heads is invoked by the following commands. Table 48: Device behavior by ATA command Command Response Standby UL -> Comp. Standby Immediate UL -> Comp. Sleep UL -> Comp. Reset Response Soft Reset Rdy (*1) Hard Reset UL -> Rdy UL = unload Comp = complete Rdy = interface ready (*1) Load/Unload condition is not changed by Soft Reset Load is also invoked as the idle command. The specified start/stop life of the product assumes that load/unload is operated normally, NOT in emergency mode. 11.4.2 Emergency unload When the drive power is interrupted with the heads still loaded, the microcode cannot operate and the normal 5V power is unavailable to unload the heads. In this case, normal unload is not possible, so the heads are unloaded by routing the back EMF of the spinning motor to the voice coil. The actuator velocity is greater than the normal case, and the unload process is inherently less controllable without a normal seek current profile. Emergency unload is intended to be invoked in rare situations. Because this operation is inherently uncontrolled, it is more mechanically stressful than a normal unload. A single emergency unload operation is more stressful than 100 normal unloads. Use of emergency unload reduces the start/stop life of the drive at a rate at least 100 times faster than that of normal unload and may damage the drive. 11.4.3 Required power-off sequence The following are examples of such problems which can result when power is removed on most drives at an arbitrary time: • Data is lost from the write buffer. • If the drive is writing a sector, a partially-written sector with an incorrect ECC block results, the sector contents are destroyed, and reading that sector results in a hard error. • Heads may land in the data zone instead of the landing zone depending on the design of the drive. Travelstar 80GN Hard Disk Drive Specification 72 You may then turn off the drive in the following order: 1. Issue Standby Immediate or sleep command 2. Wait until COMMAND COMPLETE STATUS is returned. (It may take up to 350 ms in a typical case.) 3. Terminate power to drive This power-down sequence should be followed for entry into any system power-down state, system suspend state, or system hibernation state. In a robustly designed system, emergency unload is limited to rare scenarios such as battery removal during operation. 11.5 Sector Addressing Mode All addressing of data sectors recorded on the device's media is done by a logical sector address. The logical CHS address for the drive is different from the actual physical CHS location of the data sector on the disk media. The drive supports both Logical CHS Addressing Mode and LBA Addressing Mode as the sector addressing mode. The host system may select either the currently selected CHS translation addressing or LBA addressing on a command-by-command basis by using the L bit in the DEVICE/HEAD register. A host system must set the L bit to 1 if the host uses LBA Addressing mode. 11.5.1 Logical CHS addressing mode The logical CHS addressing is made up of three fields: the cylinder number, the head number, and the sector number. Sectors are numbered from 1 to the maximum value allowed by the current CHS translation mode but cannot exceed 255 (0FFh). Heads are numbered from 0 to the maximum value allowed by the current CHS translation mode but cannot exceed 15 (0Fh). Cylinders are numbered from 0 to the maximum value allowed by the current CHS translation mode but cannot exceed 65535 (0FFFFh). When the host selects a CHS translation mode using the INITIALIZE DEVICE PARAMETERS command, the host requests the number of sectors per logical track and the number of heads per logical cylinder. The device then computes the number of logical cylinders available in requested mode. The default CHS translation mode is described in the Identify Device Information. The current CHS translation mode also is described in the Identify Device Information. 11.5.2 LBA addressing mode Logical sectors on the device shall be linearly mapped with the first LBA addressed sector (sector 0) being the same sector as the first logical CHS addressed sector (cylinder 0, head 0, sector 1). Irrespective of the logical CHS translation mode currently in effect, the LBA address of a given logical sector does not change. The following formula is always true: LBA = ((cylinder x heads_per_cylinder + heads) x sectors_per_track) + sector – 1 where heads_per_cylinder and sectors_per_track are the current translation mode values. On LBA addressing mode, the LBA value is set to the following register: Device <- - - LBA bits 27–24 LBA High <- - - LBA bits 23–16 LBA Mid <- - - LBA bits 15–8 LBA Low <- - - LBA bits 7–0 Travelstar 80GN Hard Disk Drive Specification 73 11.6 Power management features The power management feature set permits a host to modify the behavior in a manner which reduces the power required to operate. The power management feature set provides a set of commands and a timer that enables a device to implement low power consumption modes. The drive implements the following set of functions: • A Standby timer • Idle command • Idle Immediate command • Sleep command • Standby command • Standby Immediate command 11.6.1 Power mode Sleep Mode The lowest power consumption when the device is powered on occurs in Sleep Mode. When in Sleep Mode, the device requires a reset to be activated. Standby The device interface is capable of accepting commands, but since the media may not be Mode immediately accessible, there is a delay while waiting for the spindle to reach operating speed. Idle Mode Refer to Section 11.7 “Advanced Power Management (ABLE-3) feature” on page 75. Active The device is in execution of a command or accessing the disk media with the read look- Mode ahead function or the write cache function. 11.6.2 Power management commands The Check Power Mode command allows a host to determine if a device is currently in, going to, or leaving standby mode. The Idle and Idle Immediate commands move a device to idle mode immediately from the active or standby modes. The idle command also sets the standby timer count and starts the standby timer. The sleep command moves a device to sleep mode. The device's interface becomes inactive at the completion of the sleep command. A reset is required to move a device out of sleep mode. When a device exits sleep mode it will enter standby mode. The Standby and Standby Immediate commands move a device to standby mode immediately from the active or idle modes. The standby command also sets the standby timer count. 11.6.3 Standby/Sleep command completion time 1. Confirm the completion of writing cached data in the buffer to media. 2. Unload the heads on the ramp. 3. Set the DRDY bit and the DSC bit in Status Register. 4. Set the INTRQ (completion of the command). 5. Activate the spindle break to stop the spindle motor. 6. Wait until the spindle motor is stopped. 7. Perform the post process. Travelstar 80GN Hard Disk Drive Specification 74 11.6.4 Standby timer The standby timer provides a method for the device to automatically enter standby mode from either active or idle mode following a host programmed period of inactivity. If the device is in the active or idle mode, the device waits for the specified time period and if no command is received, the device automatically enters the standby mode. If the value of the SECTOR COUNT register on Idle command or the Standby command is set to "00h", the device will automatically set the standby timer to 109 minutes. 11.6.5 Status In the active, idle, and standby modes, the device shall have the RDY bit of the status register set. If the BSY bit is not set, the device shall be ready to accept any command. In sleep mode, the device's interface is not active. A host shall not attempt to read the status of the device or issue commands to the device. 11.6.6 Interface capability for power modes Each power mode affects the physical interface as defined in the following table: Table 49: Power conditions Mode BSY RDY Interface active Media Active x x Yes Active Idle o 1 Yes Active Standby o 1 Yes Inactive Sleep x x No Inactive Ready (RDY) is not a power condition. A device may post ready at the interface even though the media may not be accessible. The interface is inactive in sleep mode, but the access to the interface registers and the validity of INTRQ is guaranteed for two seconds after the Sleep command is completed. After this period, the contents of interface registers may be lost. Since the contents of interface registers may be invalid, the host should NOT check the Status register nor the Alternate Status register prior to issuing a soft reset to wake up a device. 11.6.7 Initial Power Mode at Power On After power on or hard reset the device goes to IDLE mode or STANDBY mode depending on the option. Refer to section 4.4.3 “Operating modes” on page 19 for the initial power mode selection. 11.7 Advanced Power Management (ABLE-3) feature This feature provides power saving without performance degradation. The Adaptive Battery Life Extender 3 (ABLE-3) technology intelligently manages transition among power modes within the device by monitoring access patterns of the host. This technology has three idle modes; Performance Idle mode, Active Idle mode, and Low Power Idle mode. This feature allows the host to select an advanced power management level. The advanced power management level is a scale from the lowest power consumption setting of 01h to the maximum performance level of FEh. Device performance may increase with increasing advanced power management levels. Device power consumption may Travelstar 80GN Hard Disk Drive Specification 75 increase with increasing advanced power management levels. The advanced power management levels contain discrete bands, described in the section of Set Feature command in detail. This feature set uses the following functions: • A SET FEATURES subcommand to enable Advanced Power Management • A SET FEATURES subcommand to disable Advanced Power Management The Advanced Power Management feature is independent of the Standby timer setting. If both Advanced Power Management level and the Standby timer are set, the device will go to the Standby state when the timer times out or the device's Advanced Power Management algorithm indicates that it is time to enter the Standby state. The IDENTIFY DEVICE response word 83, bit 3 indicates that Advanced Power Management feature is supported if set. Word 91, bit 7-0 indicates that Advanced Power Management is enabled if set. Word 91, bits 7-0 contain the current Advanced Power Management level if Advanced Power Management is enabled. 11.7.1 Performance Idle Mode This mode is usually entered immediately after Active mode command processing is complete, instead of conventional idle mode. In Performance Idle mode, all electronic components remain powered and full frequency servo remains operational. This provides instantaneous response to the next command. The duration of this mode is intelligently managed as described below. 11.7.2 Active Idle Mode In this mode, power consumption is 45–55% less than that of Performance Idle mode. Additional electronics are powered off and the head is parked near the mid-diameter of the disk without servoing. Recovery time to Active mode is about 20 ms. 11.7.3 Low Power Idle Mode Power consumption is 60–65% less than that of Performance Idle mode. The heads are unloaded on the ramp but the spindle is still rotated at the full speed. Recovery time to Active mode is about 300ms. 11.7.4 Transition time The transition time is dynamically managed by the user's recent access pattern, instead of fixed times. The ABLE-3 algorithm monitors the interval between commands instead of the command frequency of ABLE-2. The algorithm supposes that the next command will come with the same command interval distribution as the previous access pattern. The algorithm calculates the expected average saving energy and response delay for next command in several transition time case based on this assumption. And it selects the most effective transition time with the condition that the calculated response delay is shorter than the value calculated from the specified level by Set Feature Enable Advanced Power Management command. The optimal time to enter Active Idle mode is variable depending on the recent behavior of the user. It is not possible to achieve the same level of Power savings with a fixed entry time into Active Idle because every user's data and access pattern is different. The optimum entry time changes over time. The same algorithm works for entering into Low Power Idle mode and Standby mode, which consumes less power but needs more recovery time switching from this mode to Active mode. Travelstar 80GN Hard Disk Drive Specification 76 11.8 S.M.A.R.T. Function The intent of Self-monitoring, analysis, and reporting technology (S.M.A.R.T.) is to protect user data and prevent unscheduled system downtime that may be caused by predictable degradation and/or fault of the device. By monitoring and storing critical performance and calibration parameters, S.M.A.R.T. devices employ sophisticated data analysis algorithms to predict the likelihood of near-term degradation or fault condition. By alerting the host system of a negative reliability status condition, the host system can warn the user of the impending risk of a data loss and advise the user of appropriate action. Since S.M.A.R.T. utilizes the internal device microprocessor and other device resources, there may be some small overhead associated with its operation. However, special care has been taken in the design of the S.M.A.R.T. algorithms to minimize the impact to host system performance. Actual impact of S.M.A.R.T. overhead is dependent on the specific device design and the usage patterns of the host system. To further ensure minimal impact to the user, S.M.A.R.T. capable devices are shipped from the device manufacturer's factory with the S.M.A.R.T. feature disabled. S.M.A.R.T. capable devices can be enabled by the system OEMs at time of system integration or in the field by after-market products. 11.8.1 Attributes Attributes are the specific performance or calibration parameters that are used in analyzing the status of the device. Attributes are selected by the device manufacturer based on that attribute's ability to contribute to the prediction of degrading or faulty conditions for that particular device. The specific set of attributes being used and the identity of these attributes is vendor specific and proprietary. 11.8.2 Attribute values Attribute values are used to represent the relative reliability of individual performance or calibration attributes. Higher attribute values indicate that the analysis algorithms being used by the device are predicting a lower proba- bility of a degrading or fault condition existing. Accordingly, lower attribute values indicate that the analysis algo- rithms being used by the device are predicting a higher probability of a degrading or fault condition existing. There is no implied linear reliability relationship corresponding to the numerical relationship between different attribute values for any particular attribute. 11.8.3 Attribute thresholds Each attribute value has a corresponding attribute threshold limit which is used for direct comparison to the attribute value to indicate the existence of a degrading or faulty condition. The numerical value of the attribute thresholds are determined by the device manufacturer through design and reliability testing and analysis. Each attribute threshold represents the lowest limit to which its corresponding attribute value can be equal while still retaining a positive reliability status. Attribute thresholds are set at the device manufacturer's factory and cannot be changed in the field. The valid range for attribute thresholds is from 1 through 253 decimal. 11.8.4 Threshold exceeded condition If one or more attribute values are less than or equal to their corresponding attribute thresholds, then the device reliability status is negative, indicating an impending degrading or faulty condition. 11.8.5 S.M.A.R.T. commands The S.M.A.R.T. commands provide access to attribute values, attribute thresholds and other logging and reporting information. Travelstar 80GN Hard Disk Drive Specification 77 11.8.6 S.M.A.R.T. operation with power management modes The device saves attribute values automatically on every head unload timing except the emergency unload, even if the attribute auto save feature is not enabled. The head unload is done not only by Standby, Standby Immediate, Sleep command, and Hard Reset, but also by the Standby timer. So it is not necessary for a host system to enable the attribute auto save feature when it utilizes the power management. If the attribute auto save feature is enabled, attribute values will be saved after 30 minutes have passed since the last saving, besides above condition. 11.9 Security Mode Feature Set Security Mode Feature Set is a powerful security feature. With a device lock password, a user can prevent unauthorized access to a device even if it is removed from the computer. New commands are supported for this feature as listed below: Security Set Password ('F1'h) Security Unlock ('F2'h) Security Erase Prepare ('F3'h) Security Erase Unit ('F4'h) Security Freeze Lock ('F5'h) Security Disable Password ('F6'h) 11.9.1 Security mode The following security modes are provided: Device Locked The device disables media access commands after power on. Media access Mode commands are enabled by either a Security Unlock command or a Security Erase Unit command. Device Unlocked The device enables all commands. If a password is not set this mode is entered after Mode power on, otherwise it is entered by a Security Unlock or a Security Erase Unit command. Device Frozen Mode The device enables all commands except those which can update the device lock function, set/change password. The device enters this mode via a Security Freeze Lock command. It cannot quit this mode until power off. 11.9.2 Security level The following security levels are provided: High level security When the device lock function is enabled and the User Password is forgotten, the device can be unlocked via a Master Password. Maximum level When the device lock function is enabled and the User Password is forgotten, security then only the Master Password with a Security Erase Unit command can unlock the device. Then user data is erased. Travelstar 80GN Hard Disk Drive Specification 78 11.9.3 Password This function can have two types of passwords as described below. Master Password When the Master Password is set, the device does NOT enable the Device Lock Function, and the device CANNOT be locked with the Master Password, but the Master Password can be used for unlocking the locked device. User Password The User Password should be given or changed by a system user. When the User Password is set, the device enables the Device Lock Function, and then the device is locked on the next power on reset or hard reset. The system manufacturer or dealer who intends to enable the device lock function for end users must set the master password even if only single level password protection is required. Otherwise, the default master password which is set by Hitachi Global Storage Technologies can unlock a device that is locked with a user password 11.9.4 Master Password Revision Code This Master Password Revision Code is set by Security Set Password command with the master password. And this revision code field is returned in the Identify Device command word 92. The valid revision codes are 0001h to FFFEh. The default value of Master Password Revision Code is FFFEh. Values 0000h and FFFFh are reserved. 11.9.4.1 Master Password setting The system manufacturer or dealer can set an initial Master Password using the Security Set Password command, without enabling the Device Lock Function. 11.9.4.2 User Password setting When a User Password is set, the device will automatically enter lock mode the next time the device is powered on. Table 50: Initial setting < Setting password > < No setting password > POR POR Set Password with User Password Normal operation Normal operation Power off POR Device unlocked mode Power off POR Device locked mode Travelstar 80GN Hard Disk Drive Specification 79 11.9.4.3 Operation from POR after user password is set When Device Lock Function is enabled, the device rejects media access command until a Security Unlock command is successfully completed.

Travelstar 80GN Hard Disk Drive Specification 80 11.9.4.4 User Password lost If the User Password is forgotten and High level security is set, the system user cannot access any data. However the device can be unlocked using the Master Password. If a system user forgets the User Password and Maximum security level is set, data access is impossible. However the device can be unlocked using the Security Erase Unit command to unlock the device and erase all user data with the Master Password. Table 52: Password lost User Password Lost Unlock EMD with Master Password LEVEL ? High Maximum Normal operation Erase Prepare Command Erase Unit Command with Master Password Normal operation but data lost 11.9.4.5 Attempt limit for the SECURITY UNLOCK command The SECURITY UNLOCK command has an attempt limit the purpose of which is to prevent someone from attempting to unlock the drive with various passwords numerous times. The device counts the password mismatch. If the password does not match, the device counts it without distinguishing the Master password and the User password. If the count reaches 5, EXPIRE bit (bit 4) of Word 128 in Identify Device information is set, and then the SECURITY ERASE UNIT command and the SECURITY UNLOCK command are aborted until a hard reset or a power off. The count and EXPIRE bit are cleared after a power on reset or a hard reset. Travelstar 80GN Hard Disk Drive Specification 81 11.9.5 Command table This table shows the device's response to commands when the Security Mode Feature Set (Device lock function) is enabled.

This protected area is used to contain critical system data such as BIOS or system management information. The contents of the entire system main memory may also be dumped into the protected area to resume after a system power off. The LBA/CYL changed by the following commands affects the Identify Device Information. Two commands are defined for this function: • Read Native Max ADDRESS ('F8'h) • Set Max ADDRESS ('F9'h) Four security extension commands are implemented as sub functions of the Set Max ADDRESS: • Set Max SET PASSWORD • Set Max LOCK • Set Max FREEZE LOCK • Set Max UNLOCK 11.10.1 Example for operation (In LBA Mode) The following example uses hypothetical values. Device characteristics: Capacity (native) 536,870,912 bytes (536MB) Max LBA (native) 1,048,575 (0FFFFFh) Required size for protected area 8,388,608 bytes Required blocks for protected area 16,384 (004000h) Customer usable device size 528,482,304 bytes (528MB) Customer usable sector count 1,032,192 (0FC000h) LBA range for protected area 0FC000h to 0FFFFFh 1. Shipping drives from the drive manufacturer When the drive is shipped from the manufacturer, the device has been tested to have a capacity of 536MB, flagging the media defects not visible by the system. 2. Preparing drives at system manufacturer Special utility software is required to define the size of the protected area and to store the data in it. The sequence is: Travelstar 80GN Hard Disk Drive Specification 83 Issue Read Native Max ADDRESS command to get the real device max of LBA/CYL. Returned value shows that native device Max LBA is 0FFFFFh regardless of the current setting. Make the entire device accessible, including the protected area, by setting the device Max LBA as 0FFFFFh via Set Max ADDRESS command. The option could be either nonvolatile or volatile. Test the sectors for protected area (LBA > = 0FC000h) if required. Write information data such as BIOS code within the protected area. Change maximum LBA using Set Max ADDRESS command to 0FBFFFh with nonvolatile option. From this point, the protected area cannot be accessed until next Set Max ADDRESS command is issued. Any BIOS, device driver, or application software accesses the drive as if it is a 528 MB device because the device behaves like a 528 MB device. 3. Conventional usage without system software support: Since the drive works as a 528 MB device, there is no special care required for normal use of this device. 4. Advanced usage using protected area. The data in the protected area is accessed by the following steps. 1. Issue Read Native Max ADDRESS command to get the real device max LBA/CYL. Returned value shows that native device Max LBA is 0FFFFFh regardless of the current setting. 2. Make entire device accessible, including the protected area, by setting device Max LBA as 0FFFFFh via Set Max ADDRESS command with the volatile option. By using this option, unexpected power removal or reset will prevent the protected area from remaining accessible. 3. Read information data from protected area. 4. Issue hard reset or POR to inhibit any access to the protected area. 11.10.2 Set Max security extension commands The Set Max SET PASSWORD command allows the host to define the password to be used during the current power on cycle. This password is not related to the password used for the Security Mode Feature set. When the password is set, the device is in the Set Max Unlocked mode. This command requests a transfer of a single sector of data from the host. The following figure defines the content of this sector of information. The password is retained by the device until the next power cycle. When the device accepts this command, the device is in Set Max Unlocked mode. Table 54: Set Max SET PASSWORD data content Word Content 0 Reserved 1-16 Password (32 bytes) 17-255 Reserved The Set Max LOCK command allows the host to disable the Set Max commands (except Set Max UNLOCK and Set Max FREEZE LOCK) until the next power cycle or the issuance and acceptance of the Set Max UNLOCK command. When this command is accepted, the device is in the Set Max Locked mode. The Set Max UNLOCK command changes the device from the Set Max Locked mode to the Set Max Unlocked mode. Travelstar 80GN Hard Disk Drive Specification 84 This command requests a transfer of a single sector of data from the host. The figure shown above defines the content of this sector of information. The password supplied in the sector of data transferred is compared with the stored Set Max password. If the password compare fails, then the device returns command aborted and decrements the unlock counter. On the acceptance of the Set Max LOCK command, this counter is set to a value of five and is decremented for each password mismatch when Set Max UNLOCK is issued and the device is locked. When this counter reaches zero, then the Set Max UNLOCK command returns command aborted until a power cycle. The Set Max FREEZE LOCK command allows the host to disable the SET MAX commands (including Set Max UNLOCK) until the next power cycle. When this command is accepted the device is in the Set Max Frozen mode. The password, the Set Max security mode, and the unlock counter do not persist over a power cycle but persist over a hardware or software reset. NOTE: If this command is immediately preceded by a Read Native MAX ADDRESS command, it shall be interpreted as a Set Max ADDRESS command regardless of Feature register value. Table 55: Set Max security mode transition 11.11 Address Offset Feature (vendor specific) Computer systems perform initial code loading (booting) by reading from a predefined address on a disk drive. To allow an alternate bootable operating system to exist in a reserved area on a disk drive this feature provides a Set Features function to temporarily offset the drive address space. The offset address space wraps around so that the entire disk drive address space remains addressable in offset mode. The Set Max pointer is set to the end of the reserved area to protect the data in the user area when operating in offset mode. This protection can be removed by a Set Max Address command to move the Set Max pointer to the end of the drive. But any commands which access sectors across the original native maximum LBA are rejected with error, even if this protection is removed by a Set Max Address command. 11.11.1 Enable/Disable Address Offset Mode Subcommand code 09h Enable Address Offset Mode offsets address Cylinder 0, Head 0, Sector 1, LBA 0, to the start of the nonvolatile protected area established using the Set Max Address command. The offset condition is Travelstar 80GN Hard Disk Drive Specification 85 cleared by Subcommand 89h Disable Address Offset Mode, Hardware reset or Power on Reset. If Reverting to Power on Defaults has been enabled by Set Features command, it is cleared by Soft reset as well. Upon entering offset mode the capacity of the drive returned in the Identify Device data is the size of the former protected area. A subsequent Set Max Address command with the address returned by the Read Max Address command allows access to the entire drive. Addresses wrap so the entire drive remains addressable. If a nonvolatile protected area has not been established before the device receives a Set Features Enable Address Offset Mode command, the command fails with Abort error status. Disable Address Offset Feature removes the address offset and sets the size of the drive reported by the Identify Device command back to the size specified in the last nonvolatile Set Max Address command. Table 56: Device address map before and after Set Feature 11.11.2 Identify Device Data Identify Device data, word 83, bit 7 indicates the device supports the Address Offset Feature. Identify Device data, word 86, bit 7 indicates the device is in Address Offset mode. 11.11.3 Exceptions in Address Offset Mode Any commands which access sectors across the original native maximum LBA are rejected with error, even if the access protection is removed by a Set Max Address command. Read Look Ahead operation is not carried out, even if it is enabled by the Set Feature command. Travelstar 80GN Hard Disk Drive Specification 86 11.12 Seek Overlap The drive provides accurate seek time measurement method. The seek command is usually used to measure the device seek time by accumulating execution time for a number of seek commands. With typical implementation of the seek command, this measurement must include the device and host command overhead. To eliminate this overhead, the drive overlaps the seek command as described below. The first seek command completes before the actual seek operation is over. Then the device can receive the next seek command from the host. However, the actual seek operation for the next seek command starts right after completion of the actual seek operation for the first seek command. The execution of two seek commands overlaps excluding the actual seek operation. With this overlap, total elapsed time for a number of seek commands is the total accumulated time for the actual seek operation plus one pre and post overhead. When the number of seeks is large, this overhead can be ignored. Table 57: Seek overlap (1) With overlap Host process Device process Seek operation Overhead A B Total time = (n-1) * (Seek operation) + A + B (2) Without overlap Host process Device process Seek operation B Overhead A B+A B+A Total time = n * (Seek operation + A + B) 11.13 Write Cache function Write cache is a performance enhancement whereby the device reports completion of the write command (Write Sectors and Write Multiple) to the host as soon as the device has received all of the data in its buffer. The device assumes responsibility to write the data subsequently onto the disk. • While writing data after completed acknowledgment of a write command, soft reset, or hard reset does not affect its operation. But power off terminates writing operation immediately and unwritten data is lost. • Flush cache, Soft reset, Standby, Standby Immediate, and Sleep are executed after the comple- tion of writing to disk media on enabling write cache function. The host system can confirm the completion of write cache operation by issuing flush cache command, Soft reset, Standby command, Standby Immediate command, or Sleep command, and confirming the completion of the issued command. Travelstar 80GN Hard Disk Drive Specification 87 11.14 Reassign Function The Reassign Function is used with read commands and write commands. The sectors of data for reassignment are prepared as the spare data sector. The one entry can register 256 consecutive sectors maximum. This reassignment information is registered internally, and the information is available right after completing the reassign function. Also the information is used on the next power on reset or hard reset. If the number of the spare sector reaches 0 sector, the reassign function will be disabled automatically. The spare tracks for reassignment are located at regular intervals from Cylinder 0. As a result of reassignment, the physical location of logically sequenced sectors is dispersed. 11.14.1 Auto Reassign Function The sectors that show some errors may be reallocated automatically when specific conditions are met. The spare tracks for reallocation are located at regular intervals from Cylinder 0. The conditions for auto-reallocation are described below. Nonrecovered write errors When a write operation can not be completed after the Error Recovery Procedure (ERP) is fully carried out, the sector(s) are reallocated to the spare location. An error is reported to the host system only when the write cache is disabled and the auto reallocation fails. If the number of available spare sectors reaches 16 sectors, the write cache function will be disabled automatically. Nonrecovered read errors When a read operation fails after a defined ERP is fully carried out, a hard error is reported to the host system. This location is registered internally as a candidate for the reallocation. When a registered location is specified as a target of a write operation, a sequence of media verifications is performed automatically. When the result of this verification meets the criteria, this sector is reallocated. Recovered read errors When a read operation for a sector fails once and then is recovered at the specific ERP step, this sector of data is reallocated automatically. A media verification sequence may be run prior to the relocation according to the predefined conditions. Travelstar 80GN Hard Disk Drive Specification 88 11.15 48-bit Address Feature Set The 48-bit Address feature set allows devices with capacities up to 281,474,976,710,655 sectors. This allows device capacity up to 144,115,188,075,855,360 bytes. In addition, the number of sectors that may be transferred by a single command are increased by increasing the allowable sector count to 16 bits. • Commands unique to the 48-bit Address feature set are: • Flush Cache Ext • Read DMA Ext • Read Multiple Ext • Read Native Max Address Ext • Read Sector(s) Ext • Read Verify Sector(s) Ext • Set Max Address Ext • Write DMA Ext • Write Multiple Ext • Write Sector(s) Ext The 48-bit Address feature set operates in LBA addressing only. Devices also implement commands using 28-bit addressing, and 28-bit and 48-bit commands may be intermixed. In a device, the Features, the Sector Count, the LBA Low/Mid/High registers are a two-byte-deep FIFO. Each time one of these registers is written, the new content written is placed into the "most recently written" location and the previous content is moved to "previous content" location. The host may read the "previous content" of the Features, the Sector Count, the LBA Low/Mid/High registers by first setting the High Order Bit (HOB, bit 7) of the Device control register to one and then reading the desired register. If HOB in the Device Control register is cleared to zero, the host reads the "most recently written" content when the register is read. A write to any Command Block register shall cause the device to clear the HOB bit to zero in the Device Control register. The "most recently written" content always gets written by a register write regardless of the state of HOB in the Device Control register. Support of the 48-bit Address feature set is indicated in the Identify Device response bit 10 word 83. In addition, the maximum user LBA address accessible by 48-bit addressable commands is contained in Identify Device response words 100 through 103. When the 48-bit Address feature set is implemented, the native maximum address is the value returned by a Read Native Max Address Ext command. If the native maximum address is equal to or less than 268,435,455, a Read Native Max Address shall return the native maximum address. If the native maximum address is greater than 268,435,455, a Read Native Max Address shall return a value of 268,435,455. Travelstar 80GN Hard Disk Drive Specification 89 Travelstar 80GN Hard Disk Drive Specification 90 12.0 Command protocol The commands are grouped into different classes according to the protocols followed for command execution. The command classes with their associated protocols are defined below. For all commands, the host must first check to see if BSY = 1, and should proceed no further unless and until BSY = 0. For all commands, the host must also wait for RDY = 1 before proceeding. A device must maintain either BSY = 1 or DRQ = 1 at all times until the command is completed. The INTRQ sig- nal is used by the device to signal most, but not all, times when the BSY bit is changed from 1 to 0 during com- mand execution. A command shall only be interrupted with a hardware or software reset. The result of writing to the Command reg- ister while BSY = 1 or DRQ = 1 is unpredictable and may result in data corruption. A command should only be interrupted by a reset at times when the host thinks there may be a problem, such as a device that is no longer responding. Interrupts are cleared when the host reads the Status Register, issues a reset, or writes to the Command Register. See Section 14.0, “Time-out values” on page 193 for the device time-out values. 12.1 Data In commands The following are Data In commands: • Identify Device •Read Buffer •Read Long • Read Multiple • Read Multiple EXT • Read Sector(s) • Read Sector(s) EXT • S.M.A.R.T. Read Attribute Values • S.M.A.R.T. Read Attribute Thresholds • S.M.A.R.T. Read log sector Execution includes the transfer of one or more 512 byte (> 512 bytes on Read Long) sectors of data from the device to the host. 1. The host writes any required parameters to the Features, Sector Count, LBA, Cylinder, and Device Regis- ters. 2. The host writes the command code to the Command Register. 3. For each sector (or block) of data to be transferred: a. The device sets BSY = 1 and prepares for data transfer. b. When a sector (or block) of data is available for transfer to the host, the device sets BSY = 0, sets DRQ = 1, and interrupts the host. c. In response to the interrupt, the host reads the Status Register. d. The device clears the interrupt in response to the Status Register being read. e. The host reads one sector (or block) of data via the Data Register. f. The device sets DRQ = 0 after the sector (or block) has been transferred to the host. Travelstar 80GN Hard Disk Drive Specification page 91 4. For the Read Long command: a. The device sets BSY = 1 and prepares for data transfer. b. When the sector of data is available for transfer to the host, the device sets BSY = 0 and DRQ=1 and interrupts the host. c. In response to the interrupt, the host reads the Status Register. d. The device clears the interrupt in response to the Status Register being read. e. The host reads the sector of data including ECC bytes via the Data Register. f. The device sets DRQ = 0 after the sector has been transferred to the host. The Read Multiple command transfers one block of data for each interrupt. The other commands transfer one sec- tor of data for each interrupt. Note that the status data for a sector of data is available in the Status Register before the sector is transferred to the host. If the device detects an invalid parameter, then it will abort the command by setting BSY = 0, ERR = 1, ABT = 1, and interrupting the host. If an error occurs, the device will set BSY = 0, ERR = 1, and DRQ = 1. The device will then store the error status in the Error Register and interrupt the host. The registers will contain the location of the sector in error. The error location will be reported using CHS mode or LBA mode. The mode is decided by the mode select bit (bit 6) of the Device/Head register upon issuing the command. If an Uncorrectable Data Error (UNC = 1) occurs, the defective data will be transferred from the media to the sector buffer and will be available for transfer to the host at the host's option. In case of a Read Multiple command, the host should complete transfer of the block which includes the error from the sector buffer and terminate whatever type of error that occurred. All data transfers to the host through the Data Register are 16 bits. The ECC bytes are an exception having only 8 bits. 12.2 Data Out Commands The following are Data Out commands: • Device Configuration SET •Format Track • Security Disable Password • Security Erase Unit • Security Set Password • Security Unlock • Set Max SET PASSWORD • Set Max UNLOCK • S.M.A.R.T. Write log sector • Write Buffer • Write Long • Write Multiple • Write Miltiple EXT • Write Sector(s) Travelstar 80GN Hard Disk Drive Specification page 92 • Write Sector(s) EXT • Write Verify Execution includes the transfer of one or more 512 byte (> 512 bytes on Write Long) sectors of data from the host to the device. 1. The host writes any required parameters to the Features, Sector Count, LBA, and Device Registers. 2. The host writes the command code to the Command Register. 3. The device sets BSY = 1. 4. For each sector (or block) of data to be transferred: a. The devics BSY = 0 and DRQ = 1 when it is ready to receive a sector (or block). b. The host writes one sector (or block) of data via the Data Register. c. The device sets BSY = 1 after it has received the sector (or block). d. When the device has finished processing the sector (or block), it sets BSY = 0 and interrupts the host. e. In response to the interrupt, the host reads the Status Register. 5. For the Write Long Command: a. The device sets BSY = 0 and DRQ = 1 when it is ready to receive a sector. b. The host writes one sector of data including ECC bytes via the Data Register. c. The device sets BSY = 1 after it has received the sector. d. After processing the sector of data the device sets BSY = 0 and interrupts the host. e. In response to the interrupt, the host reads the Status Register. f. The device clears the interrupt in response to the Status Register being read. The Write Multiple command transfers one block of data for each interrupt. The other commands transfer one sec- tor of data for each interrupt. If the device detects an invalid parameter, then it will abort the command by setting BSY = 0, ERR = 1, ABT = 1, and interrupting the host. If an uncorrectable error occurs, the device will set BSY = 0 and ERR = 1, store the error status in the Error Regis- ter, and interrupt the host. The registers will contain the location of the sector in error. The error location will be reported with CHS mode or LBA mode. The mode is decided by the mode select bit (bit 6) of the Device/Head reg- ister on issuing the command. All data transfers to the host through the Data Register are 16 bits. The ECC bytes are an exception having only 8bits. 12.3 Non-data commands The following are Non-data commands: • Check Power Mode • Device Configuration FREEZE LOCK • Device Configuration RESTORE • Enable/Disable Delayed Write • Execute Device Diagnostic • Flush Cache • Flush Cache EXT Travelstar 80GN Hard Disk Drive Specification page 93 • Format Unit •Idle • Idle Immediate • Initialize Device Parameters • Read Native Max ADDRESS • Read Native Max ADDRESS EXT • Read Verify Sector(s) • Read Verify Sector(s) EXT • Recalibrate • Security Erase Prepare • Security Freeze Lock • Seek • Sense Condition • Set Features • Set Max ADDRESS • Set Max ADDRESS EXT •Set Max LOCK • Set Max FREEZE LOCK • Set Multiple Mode • Sleep • S.M.A.R.T. Disable Operations • S.M.A.R.T. Enable/Disable Attribute Auto save • S.M.A.R.T. Enable/Disable Automatic Off-line • S.M.A.R.T. Enable Operations • S.M.A.R.T. Execute Off-line Immediate • S.M.A.R.T. Return Status • S.M.A.R.T. Save Attribute Values • Standby • Standby Immediate Execution of these commands involves no data transfer: a. The host writes any required parameters to the Features, Sector Count,LBA High, LBA Mid, LBA Low, and Device Registers. b. The host writes the command code to the Command Register. c. The device sets BSY = 1. d. When the device has finished processing the command, it sets BSY = 0 and interrupts the host. e. In response to the interrupt, the host reads the Status Register. f. The device clears the interrupt in response to the Status Register being read. Travelstar 80GN Hard Disk Drive Specification page 94 12.4 DMA Data Transfer commands: •Read DMA • Read DMA EXT • Write DMA • Write DMA EXT Data transfers using DMA commands differ in two ways from PIO transfers: • Data transfers are performed using the Slave DMA channel • No intermediate sector interrupts are issued on multisector commands. Initiation of the DMA transfer commands is identical to the Read Sector or Write Sector commands with one exception: the host initializes the Slave DMA channel prior to issuing the command. The interrupt handler for DMA transfers differs in two ways: • No intermediate sector interrupts are issued on multisector commands. • The host resets the DMA channel prior to reading status from the device The DMA protocol allows high performance multitasking operating systems to eliminate processor overhead asso- ciated with PIO transfers. 1. The host initializes the Slave DMA channel. 2. The host writes any required parameters to the Features, Sector Count, Sector Number, Cylinder, and Device/Head registers. 3. The host writes command code to the Command Register. 4. The device sets DMARQ when it is ready to transfer any part of the data. 5. The host transfers the data using the DMA transfer protocol currently in effect. 6. When all of the data has been transferred, the device generates an interrupt to the host. 7. The host resets the Slave DMA channel. 8. The host reads the Status Register and, optionally, the Error Register.

Table 63: Device Configuration Overlay Features register values Value Command C0h DEVICE CONFIGURATION RESTORE C1h DEVICE CONFIGURATION FREEZE LOCK C2h DEVICE CONFIGURATION IDENTIFY C3h DEVICE CONFIGURATION SET other Reserved 13.2.1 DEVICE CONFIGURATION RESTORE (subcommand C0h) The DEVICE CONFIGURATION RESTORE command disables any setting previously made by a DEVICE CONFIGURATION SET command and returns the content of the IDENTIFY DEVICE or IDENTIFY PACKET DEVICE command response to the original settings as indicated by the data returned from the execution of a DEVICE CONFIGURATION IDENTIFY command. 13.2.2 DEVICE CONFIGURATION FREEZE LOCK (subcommand C1h) The DEVICE CONFIGURATION FREEZE LOCK command prevents accidental modification of the Device Con- figuration Overlay settings. After successful execution of a DEVICE CONFIGURATION FREEZE LOCK com- mand, all DEVICE CONFIGURATION SET, DEVICE CONFIGURATION FREEZE LOCK, DEVICE CONFIGURATION IDENTIFY, and DEVICE CONFIGURATION RESTORE commands are aborted by the device. The DEVICE CONFIGURATION FREEZE LOCK condition shall be cleared by a power-down. The DEVICE CONFIGURATION FREEZE LOCK condition shall not be cleared by hardware or software reset. Travelstar 80GN Hard Disk Drive Specification 102 13.2.3 DEVICE CONFIGURATION IDENTIFY (subcommand C2h) The DEVICE CONFIGURATION IDENTIFY command returns a 512 byte data structure via PIO data-in transfer. The content of this data structure indicates the selectable commands, modes, and feature sets that the device is capable of supporting. If a DEVICE CONFIGURATION SET command has been issued reducing the capabilities, the response to an IDENTIFY DEVICE or IDENTIFY PACKET DEVICE command will reflect the reduced set of capabilities, while the DEVICE CONFIGURATION IDENTIFY command will reflect the entire set of selectable capabilities. The format of the Device Configuration Overlay data structure is shown in Table 64: “Device Configuration Over- lay Data structure” on page 104. 13.2.4 DEVICE CONFIGURATION SET (subcommand C3h) The DEVICE CONFIGURATION SET command allows a device manufacturer or a personal computer system manufacturer to reduce the set of optional commands, modes, or feature sets supported by a device as indicated by a DEVICE CONFIGURATION IDENTIFY command. The DEVICE CONFIGURATION SET command transfers an overlay that modifies some of the bits set in words 63, 82, 83, 84, and 88 of the IDENTIFY DEVICE command response. When the bits in these words are cleared, the device no longer supports the indicated command, mode, or feature set. If a bit is set in the overlay transmitted by the device that is not set in the overlay received from a DEVICE CONFIGURATION IDENTIFY command, no action is taken for that bit. The format of the overlay transmitted by the device is described in the table in Table 64: “Device Configuration Overlay Data structure” on page 104. The restrictions on changing these bits is described in the text following that table. If any of the bit modification restrictions described are violated or any setting is changed with DEVICE CONFIGURATION SET command, the device shall return command aborted. In that case, error reason code is returned to sector count register, invalid word location is returned to LBA high register, and invalid bit location is returned to LBA Mid register. The Definition of error information is shown in Table 65: “DCO error information definition.” on page 104. ERROR INFORMATION EXAMPLE 1: After establishing a protected area with SET MAX address, if a user attempts to change maximum LBA address (DC SET or DC RESTORE), the device aborts that command and returns error reason code as below.

Both new reassign information and new defect information are available immediately after the completion of this command. They are also used on the next power on reset or hard reset. This command erases both previous information data from the device. Note that the Format Unit command initializes from LBA 0 to Native MAX LBA. Host MAX LBA is set by Initial- ize Drive Parameter or Set MAX ADDRESS command is ignored. The protected area by Set MAX ADDRESS command is also initialized. The Security Erase Prepare command should be completed immediately prior to the Format Unit command. If the device receives a Format Unit command without a prior Security Erase Prepare command, the device aborts the Format Unit command. If the Feature register is NOT 11h, the device returns an Abort error to the host. This command does not request a data transfer.

When the MASTER password is set by this command, the master password is registered internally. The device is NOT locked after next power on reset or hard reset. This command requests a transfer of a single sector of data from the host including the information specified in the table below. The data transferred controls the function of this command. Table 103: Security Set Password information Word Description 00 Control Word bit 0 : Identifier (1-Master, 0-User) bit 1-7 : Reserved bit 8 : Security level (1-Maximum, 0-High) bit 9-15 : Reserved 01-16 Password (32 bytes) 17-18 Master Password Revision Code (valid if Word0bit 0 = 1) 19-255 Reserved Identifier Zero indicates that the device should check the supplied password against the user password stored internally. One indicates that the device should check the given password against the master password stored internally. Travelstar 80GN Hard Disk Drive Specification 148 Security Level A zero indicates a High level, a one indicates a Maximum level. If the host sets the High level and the password is forgotten then the Master Password can be used to unlock the device. If the host sets the Maximum level and the user password is forgotten, only a Security Erase Prepare/Security Unit command can unlock the device and all data will be lost. Password The 32 bytes are always significant in the text of the password. Master Password Revision Code The Revision Code field is set with Master password. If Identifier is User, the Revision Code is not set. The Revi- sion Code field is returned in Identify Device word 92. The valid Revision Codes are 0000h to FFFDh. The Default Master Password Revision Code is FFFEh. The code FFFFh is reserved. The setting of the Identifier and Security level bits interact as follows: Identifier = User / Security level = High The password supplied with the command will be saved as the new user password. The security mode feature (lock function) will be enabled from the next power on. The drive may then be unlocked by either the user password or the previously set master password. Identifier = Master / Security level = High This combination will set a master password but will NOT enable the security mode feature (lock function). Identifier = User / Security level = Maximum The password supplied with the command will be saved as the new user password. The security mode feature (lock function) will be enabled from the next power on. The drive may then be unlocked by only the user pass- word. The master password previously set is still stored in the drive but may NOT be used to unlock the device. Identifier = Master / Security level = Maximum This combination will set a master password but will NOT enable the security mode feature (lock function).

If a power on reset or hard reset is done without executing the Security Disable Password command after this command is completed, the device will be in device lock mode. The password has not been changed yet. The Security Unlock command requests to transfer a single sector of data from the host including information spec- ified in the table below. If the Identifier bit is set to master and the drive is in high security mode, the password supplied will be compared with the stored master password. If the drive is in maximum security mode, the security unlock will be rejected. If the Identifier bit is set to user, the drive compares the supplied password with the stored user password. If the password compare fails, the device returns an abort error to the host and decrements the unlock attempt counter. This counter is initially set to 5 and is decremented for each password mismatch. When this counter reaches zero, all password protected commands are rejected until there is a hard reset or a power off. Word Description 00 Control Word bit 0 : Identifier (1- Master, 0- User) bit 1-15 : Reserved 01-16 Password (32 bytes) 17-255 Reserved Identifier A zero indicates that the device regards Password as the User Password. A one indicates that the device regards Password as the Master Password. The user can detect if the attempt to unlock the device has failed due to a mismatched password since this is the only reason that an abort error will be returned by the drive AFTER the password information has been sent to the device. If an abort error is returned by the device BEFORE the password data has been sent to the drive, then another problem exists.

Once the device receives this command, all accesses beyond that LBA/CYL are rejected by setting the ABORT bit in the status register. Identify the device command and Identify the device DMA command returns the LBA/CYL which is set via this command as a default value. This command implement SET MAX security extension commands as subcommands. But regardless of Feature register value, the case this command is immediately preceded by a Read Native Max ADDRESS command, it is interpreted as a Set Max ADDRESS command. The Read Native Max ADDRESS command should be issued and completed immediately prior to issuing the Set Max ADDRESS command. If it is not, this command is interpreted as a Set Max security extension command which is designated by feature register. If Set Max security mode is in the Locked or Frozen, the Set Max ADDRESS command is aborted. For more infor- mation, see section 11.10.2 “Set Max security extension commands” on page 84. In CHS mode, LBA High and LBA Mid specify the maximum cylinder number. The Head number of DEVICE and LBA Low are ignored. The default value (see default CHS in Identify device information) is used for that. In LBA mode,the Head number of Device, LBA High, LBA Mid and LBA Low specify the max LBA. This com- mand sets this LBA as the max LBA of the device. After a successful command completion, Identify Device response words (61:60) shall reflect the maximum address set with this command. If the 48-bit Address feature set is supported, the value placed in Identify Device response words (103:100) shall be the same as the value placed in words (61:60). However, if the device contains greater than 268,435,455 sectors, the capacity addressable with 28-bit commands, and the address requested is 268,435,455, the max address shall be changed to the native maximum address, the value placed in words (61:60) shall be 268,435,455 and the value placed in words (103:100) shall be the native maximum address.

Read Attribute Values subcommand from the host, the device asserts BSY, saves any updated Attribute Values to the Attribute Data sectors, asserts DRQ, clears BSY, asserts INTRQ, and then waits for the host to transfer the 512 bytes of Attribute Value information from the device via the Data Register. 13.38.1.2 S.M.A.R.T. Read Attribute Thresholds (subcommand D1h) This subcommand returns the device's Attribute Thresholds to the host. Upon receipt of the S.M.A.R.T. Read Attribute Thresholds subcommand from the host, the device asserts BSY, reads the Attribute Thresholds from the Attribute Threshold sectors, asserts DRQ, clears BSY, asserts INTRQ, and then waits for the host to transfer the 512 bytes of Attribute Thresholds information from the device via the Data Register. 13.38.1.3 S.M.A.R.T. Enable/Disable Attribute Autosave (subcommand D2h) This subcommand enables and disables the attribute auto save feature of the device. The S.M.A.R.T. Enable/Dis- able Attribute Autosave subcommand allows the device to automatically save its updated Attribute Values to the Attribute Data Sector at the timing of the first transition to Active idle mode and after 30 minutes after the last sav- ing of Attribute Values. This subcommand causes the auto save feature to be disabled. The state of the Attribute Autosave feature—either enabled or disabled—will be preserved by the device across the power cycle. A value of 00h—written by the host into the device's Sector Count Register before issuing the S.M.A.R.T. Enable/ Disable Attribute Autosave subcommand—will cause this feature to be disabled. Disabling this feature does not preclude the device from saving Attribute Values to the Attribute Data sectors during some other normal operation such as during a power-up or a power-down. A value of F1h—written by the host into the device's Sector Count Register before issuing the S.M.A.R.T. Enable/ Disable Attribute Autosave subcommand—will cause this feature to be enabled. Any other nonzero value written by the host into this register before issuing the S.M.A.R.T. Enable/Disable Attribute Autosave subcommand will not change the current Autosave status. The device will respond with the error code specified in Table 121: “S.M.A.R.T. Error Codes” on page 175. The S.M.A.R.T. Disable Operations subcommand disables the auto save feature along with the device's S.M.A.R.T. operations. Upon the receipt of the subcommand from the host, the device asserts BSY, enables or disables the Autosave fea- ture, clears BSY, and asserts INTRQ. 13.38.1.4 S.M.A.R.T. Save Attribute Values (subcommand D3h) This subcommand causes the device to immediately save any updated Attribute Values to the device's Attribute Data sector regardless of the state of the Attribute Autosave feature. Upon receipt of the S.M.A.R.T. Save Attribute Values subcommand from the host, the device asserts BSY, writes any updated Attribute Values to the Attribute Data sector, clears BSY, and asserts INTRQ. Travelstar 80GN Hard Disk Drive Specification 162 13.38.1.5 S.M.A.R.T. Execute Off-line Immediate (subcommand D4h) This subcommand causes the device to immediately initiate the set of activities that collect Attribute data in an off- line mode (off-line routine) or execute a self-test routine in either captive or off-line mode. The LBA Low register shall be set to specify the operation to be executed. LBA Low Operation to be executed 0 Execute S.M.A.R.T. off-line data collection routine immediately 1 Execute S.M.A.R.T. Short self-test routine immediately in off-line mode 2 Execute S.M.A.R.T. Extended self-test routine immediately in off-line mode 127 Abort off-line mode self-test routine 129 Execute S.M.A.R.T. Short self-test routine immediately in captive mode 130 Execute S.M.A.R.T. Extended self-test routine immediately in captive mode Off-line mode: The device executes command completion before executing the specified routine. During execu- tion of the routine the device will not set BSY nor clear DRDY. If the device is in the process of performing its rou- tine and is interrupted by a new command from the host, the device will abort or suspend its routine and service the host within two seconds after receipt of the new command. After servicing the interrupting command, the device will resume its routine automatically or not start its routine depending on the interrupting command. Captive mode: When executing self-test in captive mode, the device sets BSY to one and executes the specified self-test routine after receipt of the command. At the end of the routine, the device sets the execution result in the Self-test execution status byte (see Table 113: “Device Attribute Data Structure” on page 166) and ATA regis- ters—see definitions below—and then executes the command completion. Status Set ERR to one when the self-test has failed Error Set ABRT to one when the self-test has failed LBA Low Set to F4h when the self-test has failed LBA High Set to 2Ch when the self-test has failed 13.38.1.6 S.M.A.R.T. Read Log Sector (subcommand D5h) This command returns the specified log sector contents to the host. The 512 bytes of data are returned at a command and the Sector Count value shall be set to one. The LBA Low shall be set to specify the log sector address. Log sector address Content Type 01h S.M.A.R.T. Error Log Read Only 06h S.M.A.R.T. Self-test Log Read Only 80h-9Fh Host vendor specific Read/Write 13.38.1.7 S.M.A.R.T. Write Log Sector (subcommand D6h) This command writes 512 bytes of data to the specified log sector. The 512 bytes of data are transferred at a com- mand and the LBA Low value shall be set to one. The LBA Low shall be set to specify the log sector address (See Table 112: “S.M.A.R.T. Function Set (B0h)” on page 161). If a Read Only log sector is specified, the device returns ABRT error. 13.38.1.8 S.M.A.R.T. Enable Operations (subcommand D8h) This subcommand enables access to all S.M.A.R.T. capabilities within the device. Prior to receipt of a S.M.A.R.T. Enable Operations subcommand, Attribute Values are neither monitored nor saved by the device. The state of Travelstar 80GN Hard Disk Drive Specification 163 S.M.A.R.T.—either enabled or disabled—will be preserved by the device across power cycles. Once enabled, the receipt of subsequent S.M.A.R.T. Enable Operations subcommands will not affect any of the Attribute Values. Upon receipt of the S.M.A.R.T. Enable Operations subcommand from the host, the device asserts BSY, enables S.M.A.R.T. capabilities and functions, clears BSY, and asserts INTRQ. 13.38.1.9 S.M.A.R.T. Disable Operations (subcommand D9h) This subcommand disables all S.M.A.R.T. capabilities within the device including the device's attribute auto save feature. After receipt of this subcommand the device disables all S.M.A.R.T. operations. Non self-preserved Attribute Values will no longer be monitored. The state of S.M.A.R.T.—either enabled or disabled—is preserved by the device across power cycles. Note that this subcommand does not preclude the device's power mode attribute auto saving. Upon receipt of the S.M.A.R.T. Disable Operations subcommand from the host, the device asserts BSY, disables S.M.A.R.T. capabilities and functions, clears BSY, and asserts INTRQ. After receipt of the device of the S.M.A.R.T. Disable Operations subcommand from the host, all other S.M.A.R.T. subcommands—with the exception of S.M.A.R.T. Enable Operations—are disabled, and invalid and will be aborted by the device—including the S.M.A.R.T. Disable Operations subcommand— returning the error code as specified in Table 121: “S.M.A.R.T. Error Codes” on page 175. Any Attribute Values accumulated and saved to volatile memory prior to receipt of the S.M.A.R.T. Disable Opera- tions command will be preserved in the device's Attribute Data Sectors. If the device is re-enabled, these Attribute Values will be updated, as needed, upon receipt of a S.M.A.R.T. Read Attribute Values or a S.M.A.R.T. Save Attribute Values command. 13.38.1.10 S.M.A.R.T. Return Status (subcommand DAh) This subcommand is used to communicate the reliability status of the device to the host's request. Upon receipt of the S.M.A.R.T. Return Status subcommand the device asserts BSY, saves any updated Attribute Values to the reserved sector, and compares the updated Attribute Values to the Attribute Thresholds. If the device does not detect a Threshold Exceeded Condition, or detects a Threshold Exceeded Condition but involving attributes are advisory, the device loads 4Fh into the LBA Mid register, C2h into the LBA High register, clears BSY, and asserts INTRQ. If the device detects a Threshold Exceeded Condition for prefailure attributes, the device loads F4h into the LBA Mid register, 2Ch into the LBA High register, clears BSY, and asserts INTRQ. Advisory attributes never result in a negative reliability condition. 13.38.1.11 S.M.A.R.T. Enable/Disable Automatic Off-line (subcommand DBh) This subcommand enables and disables the optional feature that cause the device to perform the set of off-line data collection activities that automatically collect attribute data in an off-line mode and then save this data to the device's nonvolatile memory. This subcommand may either cause the device to automatically initiate or resume performance of its off-line data collection activities or cause the automatic off-line data collection feature to be dis- abled. This subcommand also enables and disables the off-line read scanning feature that cause the device to per- form the entire read scanning with defect reallocation as the part of the off-line data collection activities. Travelstar 80GN Hard Disk Drive Specification 164 The Sector Count register shall be set to specify the feature to be enabled or disabled: Sector Count Feature Description 00h Disable Automatic Off-line 01h Disable Off-line Read Scanning F8h Enable Automatic Off-line F9h Enable Off-line Read Scanning A value of zero written by the host into the device's Sector Count register before issuing this subcommand shall cause the automatic off-line data collection feature to be disabled. Disabling this feature does not preclude the device from saving attribute values to nonvolatile memory during some other normal operation such as during a power-on, during a power-off sequence, or during an error recovery sequence. A value of one written by the host into the device's Sector Count register before issuing this subcommand shall cause the off-line read scanning feature to be disabled. The Device does not perform the off-line read scanning at the off-line data collection activities which is initiated by the S.M.A.R.T. Execute Off-line Immediate (Subcom- mand D4h) or automatically if the off-line read scanning feature is disabled. A value of F8h written by the host into the device's Sector Count register before issuing this subcommand shall cause the automatic Off-line data collection feature to be enabled. A value of F9 written by the host into the device's Sector Count register before issuing this subcommand shall cause the off-line read scanning feature to be enabled. The Device perform the off-line read scanning at the off-line data collection activities which is initiated by the S.M.A.R.T. Execute Off-line Immediate (Subcommand D4h) even if the automatic off-line feature is disabled. Any other nonzero value written by the host into this register before issuing this subcommand is vendor specific and will not change the current Automatic Off-Line Data Collection and Off-line Read Scanning status. However, the device may respond with the error code specified in Table 121: “S.M.A.R.T. Error Codes” on page 175. Travelstar 80GN Hard Disk Drive Specification 165 13.38.2 Device Attribute Data Structure The following defines the 512 bytes that make up the Attribute Value information. This data structure is accessed by the host in its entirety using the S.M.A.R.T. Read Attribute Values subcommand.

Travelstar 80GN Hard Disk Drive Specification 166 13.38.2.2 Individual Attribute Data Structure The following defines the 12 bytes that make up the information for each Attribute entry in the Device Attribute Data Structure. Description Byte Offset Value Attribute ID Number (01h to FFh) 1 00h binary Status Flags 2 01h bit flags Bit 0 Pre-Failure/Advisory Bit 1 On-line Collection Bit 2-5 Reserved (may be either 0 or 1) Bit 6-15 Reserved (all 0) Attribute Value (valid values from 01h to FEh) 1 03h binary 00h invalid for attribute value -not to be used 01h minimum value 64h initial value for all attributes prior to any data collection FDh maximum value FEh value is not valid FFh invalid for attribute value-not to be used Reserved (may not be 0) 1 04h binary Reserved (may not be 0) 6 05h binary Reserved (00h) 1 0Bh binary Total Bytes 12 Attribute ID Numbers: Any nonzero value in the Attribute ID Number indicates an active attribute. The device supports following Attribute ID Numbers. The names marked with (*) indicate that the corresponding Attribute Values can be either collected on-line or off-line. ID Attribute Name 0 Indicates that this entry in the data structure is not used 1 Raw Read Error Rate (*) 2 Throughput Performance (*) 3Spin Up Time 4 Start/Stop Count 5 Reallocated Sector Count 7 Seek Error Rate 8 Seek Time Performance (*) 9 Power-On Hours Count 10 Spin Retry Count 12 Device Power Cycle Count 191 Gsense Error Rate 192 Power Off Retract Count 193 Load/Unload Cycle Count 194 Device Temperature 196 Reallocation Event Count 197 Current Pending Sector Count 198 Off-Line Scan Uncorrectable Sector Count 199 Ultra DMA CRC Error Count Travelstar 80GN Hard Disk Drive Specification 167 Table 114: Status Flag definitions Bit Flag Name Definition 0 Pre-Failure/ If bit = 0, an Attribute Value less than or equal to its Advisory bit corresponding Attribute Threshold indicates an Advisory condition where the usage or age of the device has exceeded its intended design life period. If bit = 1, an Attribute Value less than or equal to its corresponding Attribute Threshold indicates a Pre-Fail- ure condition where imminent loss of data is being pre- dicted. 1 On-Line Collective If bit = 0, the Attribute Value is updated only during bit Off-Line testing. If bit = 1, the Attribute Value is updated during On- Line testing or during both On-Line and Off-Line test- ing. 2-5 Reserved bits May either be 0 or 1 6-15 Reserved bits Always 0 Normalized values: The device will perform conversion of the raw Attribute Values to transform them into nor- malized values which the host can then compare with the Threshold values. A Threshold is the excursion limit for a normalized Attribute Value. In normalizing the raw data, the device will perform any necessary statistical validity checks to ensure that an instantaneous raw value is not improperly reflected in the normalized Attribute Value (i.e., one read error in the first 10 reads being interpreted as exceeding the read error rate threshold when the subsequent 1 billion reads all execute without error). The end points for the normalized values for all Attributes will be 1 (01h) at the low end and 100 (64h) at the high end for the device. For Performance and Error Rate Attributes, values greater than 100 are also possible. The maximum value possible is 253 (FDh). 13.38.2.3 Off-Line Data Collection Status The value of this byte defines the current status of the off-line activities of the device.
