All times are measured using drive diagnostics. The spec- ifications in the table below are defined as follows: U8 Family Product Manual, Rev. B 7 • Track-to-track seek time is an average of all possible single-track seeks in both directions. • Average seek time is a true statistical random average of at least 5,000 measurements of seeks between random tracks, less overhead. • Full-stroke seek time is one-half the time needed to seek from the first data cylinder to the maximum data cylinder and back to the first data cylinder. The full-stroke typical value is determined by averaging 100 full-stroke seeks in both directions. Typical seek times (msec) Read Write Track-to-track 1.5 2.1 Average 10.5 11.5 Full-stroke 23.0 25.0 Average latency: 5.56 msec — — Note. These drives are designed to consistently meet the seek times rep- resented in this manual. Physical seeks, regardless of mode (such as track-to-track and average) are expected to meet or exceed the noted values. However, due to the manner in which these drives are format- ted, benchmark tests that include command overhead or measure logical seeks may produce results that vary from these specifications. 1.6 Start/stop times Power-on to Ready (sec) 10 (typical) Standby to Ready (sec) 10 (typical) Ready to spindle stop (sec) 10 (typical) 1.7 Power specifications The drive receives DC power (+5V or +12V) through a four-pin standard drive power connector. 1.7.1 Power consumption Power requirements for the drives are listed in the table on page 9. Typical power measurements are based on an average of drives tested, under nominal conditions, using 5.0V input voltage at 25°C ambient temperature. • Spinup power Spinup power is measured from the time of power-on to the time that the drive spindle reaches operating speed. 8 U8 Family Product Manual, Rev. B • Seek Mode During seek mode, the read/write actuator arm moves toward a specific position on the disc surface and does not execute a read or write operation. Servo electronics are active. Seek mode power rep- resents the worst-case power consumption, using only random seeks with read or write latency time. This mode is not typical and is provided for worst-case information. • Read/Write power and current Read/write power is measured with the heads on track, based on a 16-sector write followed by a 32-msec delay, then a 16-sector read followed by a 32-msec delay. • Operating power and current Operating power is measured using 40 percent random seeks, 40 percent read/write mode (1 write for each 10 reads) and 20 percent drive inactive. • Idle mode power Idle mode power is measured with the drive up to speed, with servo electronics active and with the heads in a random track location. • Standby mode During Standby mode, the drive accepts commands, but the drive is not spinning, and the servo and read/write electronics are in power- down mode.

B 1.7.2 Conducted noise Input noise ripple is measured at the host system power supply across an equivalent 80-ohm resistive load on the +12 volt line or an equivalent 15-ohm resistive load on the +5 volt line. • Using 12-volt power, the drive is expected to operate with a maximum of 120 mV peak-to-peak square-wave injected noise at up to 10 MHz. • Using 5-volt power, the drive is expected to operate with a maximum of 100 mV peak-to-peak square-wave injected noise at up to 10 MHz. Note. Equivalent resistance is calculated by dividing the nominal volt- age by the typical RMS read/write current. 1.7.3 Voltage tolerance Voltage tolerance (including noise): 5V ± 5% and 12V ± 10% 1.7.4 Power-management modes The drive provides programmable power management to provide great- er energy efficiency. In most systems, you can control power manage- ment through the system setup program. The drive features the following power-management modes: Power Modes Heads Spindle Buffer Active Tracking Rotating Enabled Idle Tracking Rotating Enabled Standby Parked Stopped Enabled Sleep Parked Stopped Disabled • Active mode The drive is in Active mode during the read/write and seek operations. • Idle mode The buffer remains enabled, and the drive accepts all commands and returns to Active mode any time disc access is necessary. • Standby mode The drive enters Standby mode when the host sends a Standby Immediate command. If the host has set the standby timer, the drive can also enter Standby mode automatically after the drive has been inactive for a specifiable length of time. The standby timer delay is U8 Family Product Manual, Rev. B 11 established using a Standby or Idle command. In Standby mode, the drive buffer is enabled, the heads are parked and the spindle is at rest. The drive accepts all commands and returns to Active mode any time disc access is necessary. • Sleep mode The drive enters Sleep mode after receiving a Sleep command from the host. In Sleep mode, the drive buffer is disabled, the heads are parked and the spindle is at rest. The drive leaves Sleep mode after it receives a Hard Reset or Soft Reset from the host. After receiving a reset, the drive exits Sleep mode and enters Active mode with all current translation parameters intact. • Idle and Standby timers Each time the drive performs an Active function (read, write or seek), the standby timer is reinitialized and begins counting down from its specified delay times to zero. If the standby timer reaches zero before any drive activity is required, the drive makes a transition to Standby mode. In both Idle and Standby mode, the drive accepts all commands and returns to Active mode when disc access is necessary. 1.8 Environmental tolerances 1.8.1 Ambient temperature Ambient temperature is defined as the temperature of the environment immediately surrounding the drive. Actual drive case temperature should not exceed 65°C (149°F) within the operating ambient conditions. Rec- ommended measurement locations are shown in Figure 3 on page 20. Above 1,000 feet (305 meters), the maximum temperature is derated linearly to 112°F (44°C) at 10,000 feet (3,048 meters). Operating 0° to 60°C (32° to 131°F) Nonoperating –40° to 70°C (–40° to 158°F) 1.8.2 Temperature gradient Operating/Nonoperating 20°C/hr (36°F/hour) max, without condensation 12 U8 Family Product Manual, Rev.

Shock may be applied in the X, Y or Z axis. 1.8.5.1 Operating shock These drives comply with the performance levels specified in this docu- ment when subjected to a maximum operating shock of 63 Gs (based on half-sine shock pulses of 2 msec). Shocks should not be repeated more than two times per second. 1.8.5.2 Nonoperating shock The nonoperating shock level that the drive can experience without incurring physical damage or degradation in performance when subse- quently put into operation is 350 Gs (based on nonrepetitive half-sine shock pulses of 2 msec duration). 1.8.6 Vibration All vibration specifications assume that the drive is mounted securely with the input vibration applied at the drive mounting screws. Vibration may be applied in the X, Y or Z axis. U8 Family Product Manual, Rev. B 13 1.8.6.1 Operating vibration The following table lists the maximum vibration levels that the drive may expe- rience while meeting the performance standards specified in this document. 5–21 Hz 0.02-inch displacement (peak to peak) 22–350 Hz 0.5 Gs acceleration (zero to peak) 351–500 Hz 0.25 Gs acceleration (zero to peak) 1.8.6.2 Nonoperating vibration The following table lists the maximum nonoperating vibration that the drive may experience without incurring physical damage or degradation in performance when subsequently put into operation. 5–21 Hz 0.2-inch displacement (peak to peak) 22–350 Hz 5.0 Gs acceleration (zero to peak) 351–500 Hz 1.0 Gs acceleration (zero to peak) 1.9 Drive acoustics Drive acoustics are measured as overall A-weighted acoustic sound power levels (no pure tones). All measurements are generally consistent with ISO document 7779. Sound power measurements were taken under essentially free-field conditions over a reflecting plane. For all tests, the drive was oriented with the cover facing upward. Note. For seek mode tests, the drive was placed in seek mode only. The number of seeks per second is defined by the following equation: (Number of seeks per second = 0.4 / (average latency + average access time) Acoustic mode Idle mode Seek mode Sound power (bels) 3.2 (typ) 3.6 (max) 3.5 (typ) 3.9 (max) 14 U8 Family Product Manual, Rev. B 1.10 Electromagnetic susceptibility The drive operates without errors when subjected to the following: Radiated noise ≤ 3 volt/meter, 30 Hz to 500 MHz Electrostatic discharge* ≤ 10 KVolts Magnetic field strength ≤ 5 Gauss * Electrostatic discharge susceptibility is measured with the drive mounted in a representative computer system (mounted to a ground plane with an earth ground). Discharges are applied to the bezel or other external surfaces on the ground plane. 1.11 Reliability 13 Nonrecoverable read errors 1 per 10 bits read, max Mean time between failures 500,000 power-on hours (nominal power, 25°C ambient tem- perature) Contact start-stop cycles 50,000 cycles (at nominal voltage and temperature, with 60 cycles per hour and a 50% duty cycle) Preventive maintenance None required 1.12 Agency certification 1.12.1 Safety certification The drives are recognized in accordance with UL 1950 and CSA C22.2 (950) and meet all applicable sections of IEC950 and EN 60950 as tested by TUV North America. 1.12.2 Electromagnetic compatibility Hard drives that display the CE marking comply with European Union requirements specified in Electromagnetic Compatibility Directives. Testing is performed to standards EN 50082-1 and EN 55022-B. Seagate uses an independent laboratory to confirm compliance with the EC directives specified in the previous paragraph. Drives are tested in representative end-user systems. Although CE-marked Seagate drives U8 Family Product Manual, Rev. B 15 comply with the directives when used in the test systems, we cannot guarantee that all systems will comply with the directives. The drive is designed for operation inside a properly designed enclosure, with prop- erly shielded I/O cable (if necessary) and terminators on all unused I/O ports. Computer manufacturers and system integrators should confirm EMC compliance and provide CE marking for their products. Australian CE-Tick (N176) If these models have the C-Tick marking, they comply with the Australia/ New Zealand Standard AS/NZS3548 1995 and meet the Electromag- netic Compatibility (EMC) Framework requirements of Australia’s Spec- trum Management Agency (SMA). 1.12.3 FCC verification These drives are intended to be contained solely within a personal computer or similar enclosure (not attached as an external device). As such, each drive is considered to be a subassembly even when it is individually marketed to the customer. As a subassembly, no Federal Communications Commission verification or certification of the device is required. Seagate Technology, Inc. has tested this device in enclosures as de- scribed above to ensure that the total assembly (enclosure, disc drive, motherboard, power supply, etc.) does comply with the limits for a Class B computing device, pursuant to Subpart J, Part 15 of the FCC rules. Operation with noncertified assemblies is likely to result in interference to radio and television reception. Radio and television interference. This equipment generates and uses radio frequency energy and if not installed and used in strict accordance with the manufacturer’s instructions, may cause interfer- ence to radio and television reception. This equipment is designed to provide reasonable protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause interference to radio or television, which can be determined by turning the equipment on and off, you are encouraged to try one or more of the following corrective measures: • Reorient the receiving antenna. • Move the device to one side or the other of the radio or TV. • Move the device farther away from the radio or TV. • Plug the computer into a different outlet so that the receiver and computer are on different branch outlets. 16 U8 Family Product Manual, Rev.

B 17 2.0 Configuring and mounting the drive This section contains the specifications and instructions for configuring and mounting the drive. 2.1 Handling and static-discharge precautions After unpacking, and before installation, the drive may be exposed to potential handling and electrostatic discharge (ESD) hazards. Observe the following standard handling and static-discharge precautions: Caution: • The SeaShell™ replaces electrostatic discharge (ESD) bags. The SeaShell package is a shock-ribbed, transparent clamshell enclosure that limits a drive’s exposure to ESD and also protects against external shocks and stresses. The design permits attaching cables, software loading and label/barcode scanning without removing the drive from the SeaShell. This minimizes handling damage. Keep the drive in the SeaShell package until you are ready for installation. ® • The drive is enclosed in a black, flexible cover called a SeaShield . Do not remove this permanent cover—it protects the drive from electro- static discharge (ESD) and minor impact damage. The soft SeaShield cover also includes installation instructions and jumper settings. Re- moving the SeaShield voids the warranty. • Keep the drive in its static-shielded bag until you are ready to complete the installation. Do not attach any cables to the drive while it is in its static-shielded bag. • Before handling the drive, put on a grounded wrist strap, or ground yourself frequently by touching the metal chassis of a computer that is plugged into a grounded outlet. Wear a grounded wrist strap throughout the entire installation procedure. • Handle the drive by its edges or frame only. • The drive is extremely fragile—handle it with care. Do not press down on the drive top cover. • Always rest the drive on a padded, antistatic surface until you mount it in the computer. • Do not touch the connector pins or the printed circuit board. • Do not remove the factory-installed labels from the drive or cover them with additional labels. Removal voids the warranty. Some factory- installed labels contain information needed to service the drive. Other labels are used to seal out dirt and contamination. 18 U8 Family Product Manual, Rev. B 2.2 Jumper settings 2.2.1 Master/slave configuration The options jumper block shown in Figure 2 is used to configure the drive for operation. It is the 8-pin dual header between the interface connector and the power connector. Use the following settings to configure the drive as a master or a slave. Master or single drive. The drive is configured at the factory for a master or single-drive operation with a jumper set on pins 7 and 8. Drive as slave. Remove all jumpers. Drive as master with a non-ATA-compatible slave. Set a jumper on pins 5 and 6 and a jumper on pins 7 and 8. Use this jumper setting only if the drive does not work as a master with no jumpers installed. Options jumper block (J8) Master or single drive Drive is slave Master with a non-ATA- compatible slave Cable select 753 1 84 6 2 Figure 2. Master/slave jumper settings U8 Family Product Manual, Rev. B 19 2.2.2 Cable-select option Computers that use cable-select determine the master and slave drives by selecting or deselecting pin 28, CSEL, on the interface bus. Master and slave drives are determined by their physical position on the cable. To enable cable select, set a jumper on pins 5 and 6 as shown in Figure 2. Refer to your computer manual to determine whether your computer supports this option. 2.2.3 Ultra ATA/66 cable An 80-conductor 40-pin cable is required to run Ultra DMA mode 3 and 4. This cable uses even-numbered conductors connected to the ground pins to improve signal integrity. Note. The drive supports both host and drive cable detection. The host detects the 80-conductor cable by sampling pin 34, CBLID–, on the interface bus. The drive detects the 80-conductor cable by sensing a capacitor at the host side through the CBLID– signal. The result is reported in a Fast Rise Detected bit (bit 13 of word 93 in the Identify drive parameter block). 2.3 Drive mounting You can mount the drive in any orientation using four screws in the side- mounting holes or four screws in the bottom-mounting holes. See Figure 4 on page 20 for drive mounting dimensions. Follow these important mounting precautions when mounting the drive: • Allow a minimum clearance of 0.030 inches (0.76 mm) around the entire perimeter of the drive for cooling. • Use only 6-32 UNC mounting screws. • The screws should be inserted no more than 0.20 inch (5.08 mm) into the bottom mounting holes and no more than 0.14 inch (3.55 mm) into the side mounting holes. • Do not overtighten the mounting screws (maximum torque: 6 inch-lb). • Do not use a drive interface cable that is more than 18 inches long. 20 U8 Family Product Manual, Rev.

Mounting dimensions—top, side and end view U8 Family Product Manual, Rev. B 21 3.0 ATA interface These drives use the industry-standard ATA task file interface that supports 16-bit data transfers. It supports ATA programmed input/output (PIO) modes 0–4; multiword DMA modes 0–2, and Ultra DMA modes 0–4. The drive also supports the use of the IORDY signal to provide reliable high-speed data transfers. You can use a daisy-chain cable to connect two drives to a single AT host bus. For detailed information about the ATA interface, refer to the draft of AT Attachment with Packet Interface Extension (ATA/ATAPI-5), NCITS T13 1153D, subsequently referred to as the Draft ATA-5 Stan- dard. 3.1 ATA interface signals and connector pins Figure 4 on page 22 summarizes the signals on the ATA interface connector that the drive supports.

At power-on, or after a hardware or software reset, the default values of the features are as indicated above. 3.1.4 S.M.A.R.T. commands S.M.A.R.T. provides near-term failure prediction for disc drives. When S.M.A.R.T. is enabled, the drive monitors predetermined drive attributes that are susceptible to degradation over time. If self-monitoring determines that a failure is likely, S.M.A.R.T. makes a status report available to the host. Not all failures are predictable. S.M.A.R.T. predictability is limited to the attributes the drive can monitor. For more information on S.M.A.R.T. commands and implementation, see the Draft ATA-5 Standard. This drive is shipped with S.M.A.R.T. features disabled. You must have a recent BIOS or software package that supports S.M.A.R.T. to enable this feature. The table below shows the S.M.A.R.T. command codes that the drive uses. Code in Features S.M.A.R.T. Command Register D0 S.M.A.R.T. Read Data H D1 Obsolete H D2 S.M.A.R.T.
