 NOTES
 1. Jumpers for JP1, 2, and 3 should not be selected concurrently.

 2. JP1 is for Master, JP2 is for Slave, JP3 is for Cable Selection
    mode.

 3. To enable Cable Selection mode, the JP3 jumper must be installed.
    In the Cable Selection mode, the drive address is determined as
    follows:

       - When CSEL is grounded or at a low level, the drive address is
         0 (master).

       - When CSEL is open or at high level, the drive address is 1
         (slave).

    The CSEL signal, ATA interface pin 28, is controlled by the host
    system.

 4. Position JP4/JP5/JP6 are not used.

 5. JP7 is the position for an external LED.

 Drive Mounting
 --------------
 The drive functions in all axes (6 directions). Performance and error
 rate stay within specification limits even if the drive is operated
 in other orientations from which it was formatted.

 For reliable operation, it is recommended to mount the drive in the
 system securely enough to prevent excessive motion or vibration of
 the drive during seek operation or spindle rotation, using
 appropriate screws or equivalent mounting hardware. Consult with the
 issuer of this specification for the actual application, if
 necessary.

 The drive level vibration test and the shock test are to be conducted
 with the drive is mounted to the table using four bottom screws
 (6-32 UNC).


 Identification Labels
 ---------------------
 The following labels are affixed to every hard disk drive shipped
 from the manufacturing location in accordance with appropriate hard
 disk drive assembly drawing.

  - A label contaning the IBM logo, IBM part number and the statement
    "Made by IBM Japan Ltd.".

  - A label containing the drive model number, date code, formatted
    capacity, place of manufacture, and UL/CSA/TUV logos.

  - A bar code label containing the drive serial number.

  - An user designed label per agreement.

 The labels may be integrated with the other labels.


 Cabling
 -------
 The maximum cable length from the host system to the HDD, plus the
 circuit pattern length in the host system, cannot exceed 45.7 cm.


 Interface Logic Signal Levels
 -----------------------------
 The interface logic signal have the following electrical
 specifications:

  Inputs:  Input High Voltage    2.0 V min.
           Input Low Voltage     0.8 V max.

  Outputs: Output High Voltage   2.4 V min.
           Output Low Voltage    0.5 V max.



 There is a choice of 2 power connections to this drive. One DC power
 connector is designed to mate with AMP part 1-480424-0 (using AMP
 pins P/N 350078-4). The other (3 pin) DC power connector is designed
 to mate with MOLEX 5480-03 (using MOLEX pins 5479). Equivalent
 connectors may be used. Pin assignments are shown below, as viewed
 from the end of the drive.


   +-----+         +-------+
   |1 2 3|         |4 3 2 1|
   +-----+         +-------+
    | | +- GND      | | | +-- +12V
    | +--- +12V     | | +---- GND
    +----- +5V      | +------ GND
                    +-------- +5V

 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.

 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.
 Consult your IBM marketing representative if you do not have an
 approved shipping container.

 Error Register
 --------------
   +-----------------------------------+
   |       Error Register              |
   +---+---+---+----+--+----+-----+----+
   | 7 | 6 | 5 | 4  |3 | 2  |  1  | 0  |
   |BBK|UNC| 0 |IDNF|0 |ABRT|TK0NF|AMNF|
   +---+---+---+----+--+----+-----+----+

 This register contains status from the last command executed by the
 drive, or a diagnostic code.

 At the completion of any command except Execute Drive Diagnostics,
 the contents of this register are valid when ERR equals 1 in the
 status register.

 After a power on, a reset, or completion of an Execute Drive
 Diagnostic command, this register contains a diagnostic code.

 Bit Definitions
 BBK       Bad Block. BBK = 1 indicates a bad block mark was detected
           in the requested sector's ID field.

 UNC       Uncorrectable Data Error. UNC = 1 indicates an
           uncorrectable data error has been encountered.

 IDNF(IDN) ID Not Found. IDN = 1 indicates the requested sector's ID
           field could not be found.

 ABRT(ABT) Aborted Command. ABT = 1 indicates the requested command
           has been aupported to a drive status error or an invalid
           parameter in an output register.

 TK0NF     Track 0 Not Found. T0N = 1 indicates track 0 was not found
 (T0N)     during a Recalibrate command.

 AMNF(AMN) Address Mark Not Found. AMN = 1 indicates the data address
           mark has not been found after finding the correct ID field
           for the requested sector.


 Head Disk Assembly
 ------------------
 The head disk assembly (HDA) is assembled in a clean room environment
 and contains the disk and actuaor assembly. Air is constantly
 circulated and filtered when the drive is operational. Ventilation of
 HDA is accomplished via an absolute breather filter.

 The spindle is directly driven by an in-hub, brushless, sensorless DC
 drive motor. Dynamic braking is used to quickly stop the spindle.


 Actuator
 --------
 The read/write heads are mounted in the actuator. The actuator is a
 swing-arm driven by a voice coil motor. A closed-loop positioning
 servo controls the movement of the actuator. An embedded servo
 pattern supplies feedback to the positioning servo to keep the read/
 write heads centered over the desired track.

 The actuator assembly is balanced to allow vertical or horizontal
 mounting without adjustment.

 When the drive is stopped by a power-off condition, the actuator
 automatically moves the head to a dedicated landing zone outside of
 the data area, where the actuator is locked.


 Cable Noise Interference
 ------------------------
 To avoid any degradation of performance throughput or error rate when
 the interface cable is routed on top or comes in contact with the HDA
 assembly, the drive must be grounded electrically to the system frame
 by four screws. The common mode noise or voltage level difference
 between the system frame and power cable ground or AT interface cable
 ground should b ein the allowable level specified in the power
 requirement section.


 Unit Sound Power Level Testing
 ------------------------------
 Sound power emission levels are measured according to ISO 7779. The
 statistical upper limit of the A-weighted sound power levels given in
 Bels relative to 1 pico Watt are shown in the following table.

  +---------+------------------------+
  |Mode     |Statistical upper limit |
  +---------+------------------------+
  |Idle     |               4.5 Bels |
  +---------+------------------------+
  |Operating|               4.8 Bels |
  +---------+------------------------+


 Shipping Zone and Lock
 ----------------------
 A dedicated "shipping" (or "landing") zone on the disk, not on the
 data area of the disk, is provided to protect the disk data during
 shipping, movement, or storage. At power down, the heads are auto-
 matically parked and a head locking mechanism secures the heads in
 this zone.
