Using Cable Selection, the drive address depends on the condition of pin 28 for the AT interface cable. In the case when pin 28 is ground or low, the drive is a Master. If pin 28 is open or high level, the drive is a Slave.

SIGNAL DEFINITION The pin assignments of interface signals are listed as follows: PIN Signal I/O PIN Signal I/O 01 -HRESET I 02 GND 03 HD07 I/O 04 HD08 I/O 05 HD06 I/O 06 HD09 I/O 07 HD05 I/O 08 HD10 I/O 09 HD04 I/O 10 HD11 I/O 11 HD03 I/O 12 HD12 I/O 13 HD02 I/O 14 HD13 I/O 15 HD01 I/O 16 HD14 I/O 17 HD00 I/O 18 HD15 I/O 19 GND (20) Key 21 (Resv) 22 GND 23 -HIOW I 24 GND 25 -HIOR I 26 GND 27 IRODY O 28 CSEL I 29 (Resv) 30 GND 31 HIRQ O 32 -HIOCS16 O 33 HA01 I 34 -PDIAG I/O 35 HA00 I 36 HA02 I 37 -HCSO I 38 -HCSI I 39 -DASP I/O 40 GND 41 +5V Logic PWR 42 +5V Motor PWR 43 GND I 44 (Resv) Note: "O" designates an output from the Drive. "I" designates an input to the Drive. "I/O" designates an input/output common. "PWP" designates a power supply to the Drive. "(Resv)" designates reserved pins which must be left unconnected. Note: There are two input pins for +5 V power supply, "+5 V LOGIC" and "+5 V MOTOR". "+5 V LOGIC" is connected to the internal logic circuits and "+5 V MOTOR" is connected to the spindle motor and motor driver. It is possible to turn on and off "+5 V LOGIC" by an external switch circuit to reduce power consumption to the least possible. In this mode, a voltage drop out due to the motor spin up current can be reduced by connecting "+5 V MOTOR" line into the system power source directly. If the above power management option is used, all signal lines that will electrically active in the host system while the HDD is disconnected from power line shall be isolated by Three-State line drivers. Internal leakage through ESD protection circuit may pull down LPUL (Least Positive Up Level) of logic signal below the specification. Use both lines in parallel, for regular HDD application.

Seek Seek operation mode. Write Write operation mode. Read Read operation mode. Idle Spindle motor and Servo system are working normally. Other modules except the servo control and Host Interface are sleeping. Commands can be received and processed immediately. Standby Spindle motor is stopped. All modules except Interface are sleeping. Commands can be received immediately. HDD is an interrupt waiting mode with the lowest power dissipation. Notes: 1. Upon power down or Spindle stopped, a head locking mechanism will secure the heads in the ID parking position. 2. Sleep command is handled like the Standby command. Recovering from standby mode does not need soft reset nor hard reset. ELECTROMAGNETIC COMPATIBILITY The Drive meets the following EMC requirements when installed in the user system and exercised with a random accessing routine at maximum data rate: United States Federal Communication Commission (FCC) Rules and Regulation Part 15: Subject J-Computer Devices "Class B Limits." European Economic Community (EEC) directive #76/889 related to the control of radio frequency interference and the Verband Deutscher Elektrontechniker (VDE) requirements of Germany (GOP). OPERATING ENVIRONMENT Humidity: Operating Relative 8% to 90% non-condensing Non-Operating Relative 5% to 95% non-condensing Wet bulb temperature: Maximum Wet Bulb: Operating 29.4 degrees C non-condensing Non-Operating 40.0 degrees C non-condensing Elevation: Operating Altitude -50 to 3000 m Ship/Storage Altitude -150 to 30000 m Temperature: Operating 5 to 55 degrees C Storage 0 to 65 degrees C Shipping -40 to 65 degrees C Temperature Gradient 20 degrees per hour (maximum) (Operating, Storage & Shipping) Note: The system is responsible for providing sufficient air movement to maintain surface temperature below 60 degrees C at the center of top cover of the drive. AIR COOLING REQUIREMENT: The host system must provide sufficient air flow across the drive to maintain the temperature at less than 60 degrees C (measured at the center of the drives' top cover). OPERATING SHOCK The Drive will withstand (with no hard error) a 10 G half-sine wave shock pulse of 11 ms duration. NON-OPERATING SHOCK The Drive will withstand (with no permanent damage or degradation in performance) a 120 G half-sine wave shock pulse of 11 ms duration or 250 G for 2 ms. OPERATING AND NON-OPERATING VIBRATION Due to the complexity of this subject we recommend that users contact the Distributor to discuss how to perform the necessary measurements, if they believe this to be an area which requires evaluation. MECHANICAL DATA DIMENSIONS H2172-A2 H2258-A3 H2344-A4 Height (mm) 17.0 + 0.35/-0.3 17.0 + 0.35/-0.3 17.0 + 0.35/-0.3 Width (mm) 70.0 +/- 0.25 70.0 +/- 0.25 70.0 +/- 0.25 Length (mm) 100.0 +/- 0.25 100.0 +/- 0.25 100.0 +/- 0.25 Weight (gram) 173 Max 180 Max 180 Max MOUNTING ORIENTATION The drive will operate in all axes (6 directions). The drive will operate within the specified error rates when tilted +/- 5 degrees from these positions. Performance and error rate will stay within specification limits if the drive is operated in the other permissible orientations from which it was formatted Thus a drive formatted in a horizontal orientation will be able to run vertically and vice versa. The recommended mounting screw torque is 3 +/- 0.5 kgf cm. 60 146 +/- 0.6 41.6 The recommended mounting screw depth is 3.5 +/- 0.5 mm for bottom and 5.0 +/- mm for horizontal mounting. The system is responsible for mounting the drive securely enough to prevent excessive motion or vibration of the drive at seek operation or spindle rotation, using appropriate screws or equivalent mounting hardware. Consult the issuer of this specification for actual application. (6x) UNC 6-32 2 (4X) UNC 6-32 Back Front 60.3 44.4 Vibration test and shock test are to be conducted with mounting the drive to the table using bottom four screws. The maximum allowable penetration of the mounting screw is 3.5 mm. PACKAGING: The drive must be protected against Electro-Static Discharge especially when being handled. The safest way to avoid damage is to put the drive in an anti static bag before ESD wrist straps, etc are removed. 101.6 +/- 0.4 Drives should only be shipped in approved containers, severe damage can be caused to the drive if the packaging does not adequately protect against the shock levels induced when a box is dropped.
