 Mounting Orientation
 --------------------
 The drive operates in all axis (6 Directions). The drive operate
 within the specified error rates when tilted +/-5 degrees from these
 positions.

 Performance and error rate must stay within specification limits even
 if the drive is operated in the other orientations from which it was
 formatted. Thus a disk drive formatted in a horizontal orientation
 operates in the vertical position without any degradation, and vice
 versa.

 The recommended mounting screw torque is 3 +/- 0.5 kgf.cm.

 The recommended mounting screw depth is 6mm max. for bottom and
 3.5mm max. for horizontal mounting.

 The system is reponsible for mounting the drive securely enough to
 prevent from excessive motion or vibration of the drive at seek
 operation or spindle rotation, using appropriate screws or equivalent
 mounting hardware.

 Vibration test and shock test are to be conducted by mounting the
 drive to the table using bottom four screws.


 Landing Zone and Lock
 ---------------------
 A 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. After power down, a head locking mechanism secures the heads
 in this zone.


 Identification Labels
 ---------------------
 The following labels are affixed to every drive.

 1. A label placed on the top of the HDA contains the statement "Made
    by IBM" or equivalent, Part number, and MLC number.

 2. A bar code label placed on the disk drive is based on user
    request. The location is to be designated in the drawing.

 3. Labels containing the vendor's name, disk drive model number,
    serial number, place of manufacture and UL/CSA certificates.

 Except for the bar code, the labels may be integrated.


 Power Connector
 ---------------
 The DC power connector is designed to mate with AMP 1-480424-0 using
 AMP pins (part 350078-4) strip or (part 61173-4) loose piece, or
 their equivalents.

      /------------\   pin 1    +12 VDC

 SCSI Bus Electrical Characteristics
 -----------------------------------
 The interface logic signal have the following electrical
 specifications:

  Inputs:  Input High Voltage    2.3 V min.
           Input Low Voltage     0.8 V max.

  Outputs: Output High Voltage   High Impedance
           Output Low Voltage    0.5 V max./IO=48mA current


 SCSI Cable
 ----------
 The drive uses single-ended drivers and receivers which will permit
 cable lengths of up to 6 metres (19.68 feet).

 For a single ended cable a 50 conductor flat cable or a 25 signal
 twisted cable can be used with a maximum length of 6.0 meters, and a
 stub length not exceeding 0.1 meters.


 SCSI Bus Terminator
 -------------------
 The drive has an internal Active SCSI bus terminator, and can be
 controlled on/off with one jumper attached to the drive. The users of
 the drive are responsible for proper termination and power source for
 SCSI bus.

 Warranty
 --------
 The warranty will be covered by contracts.


 Actuator
 --------
 The read/write heads are mounted in the actuator. The actuator is a
 swing-arm assembly 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 elements of the heads centered over the desired track.

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

 When the drive is powered off, the actuator moves the head to a
 dedicated landing zone where the actuator is secured.


 Error Recovery
 --------------
 Errors occuring with the drive handled by the error recovery
 procedure.

 Errors that are uncorrectable after application of the error recovery
 procedures are reported to the host system as non-recoverable errors.


 Power Saving Mode
 -----------------
 Power save function will save power consumption while the drive is
 idle. The drive automatically transfers its operating mode according
 to the event and timer.


 Automatic Rewrite/Reallocate
 ----------------------------
 The target supports Auto and Recommended Reallocate for READ, WRITE,
 WRITE and VERIFY, VERIFY.

 Automatic and Recommended Reallocate operate within the read/write
 command. When an automatic reallocation occurs, the read or write
 command takes longer to complete. This operation is sometimes called
 "Auto-Reassign" due to its similarity to Reassign command. During
 this time, the target disconnects from the SCSI bus, if allowed, and
 reconnects before ending the command.

IBM       SCSI INSTALLATION

 SCSI Installation Guide Generic

 Installation requirements
 -------------------------
 To install a drive inside your computer or in an external storage
 enclosure for SCSI devices, you must have:

 1 The documentation that came with your computer or storage
   enclosure.

 2 The documentation that came with your hard drive.

 3 A small, flat blade screwdriver.

 4 A SCSI controller, which is either built into the system board or
   on an adapter inside your computer.

 5 An installation kit, if it is required for your computer. Contact
   your place of purchase if you are not sure.

 6 If you are installing this into a PS/2 computer, you will also need
   the up-to-date backup copy of your reference diskette and
   diagnostic diskette.

 WARNING: Do not open the static-protective bag containing the drive
 until instructed to do so. Static electricity can damage the drive.


 Hardware and software considerations
 Operating system
 ----------------
 The operating system and hardware are two of the factors that
 determine the number of drives a computer can support. The manuals
 for your computer and operating system can help you to determine the
 number and type of hard disk drives you can use.


 Power supply
 ------------
 Two factors that determine the number of internal drives that a
 computer or SCSI storage enclosure can support are:

 1 The available current of the power supply

 2 The nominal operating current of each drive installed

 Most computer power supplies have output over-current protection. If
 the total allowed current is exceeded, the power supply shuts down.
 The computer must be turned off and turned on again.

 SCSI ID Each SCSI device connected to a SCSI adapter must be assigned
 a unique SCSI identification number (ID). The ID you assign to this
 device depends on the number of SCSI devices connected to the SCSI
 adapter and the SCSI IDs already assigned to those devices.

 Note: All IBM SCSI controllers support SCSI IDs 6 through 0. (ID 7 is
 used for the SCSI controller.) Some SCSI controllers support SCSI IDs
 15 through 8. If your SCSI controller supports more than seven
 devices, then you can use SCSI IDs 15 through 8. If you are not sure
 if your SCSI controller supports more than seven devices, refer to
 the documentation that came with your SCSI controller for
 information.

 If you have an IBM PS/2 computer, you can view your SCSI ID settings
 by accessing the system programs. From the main menu, select Set
 configuration. The select Set and view SCSI configuration.
 Other computers might have utility programs that enable you to view
 the SCSI configuration, or you might have to physically inspect the
 installed SCSI devices to see how the IDs are set. For more
 information, refer to the documentation that came with your computer
 or SCSI controller.


 Handling precautions
 --------------------
 1 Turn off all attached devices first; then turn off the computer.

 2 Unplug all the power cords from electrical outlets before starting
   installation.

 3 Disconnect all power cables from your computer and attached devices
   before starting installation.

 4 Limit your movement. Movement can cause static electricity to build
   up around you.

 5 Handle the drive carefully and by the edges.

 6 Do not touch any exposed printed circuitry.

 7 Prevent other people from touching the components or the drive.

 8 When you are installing the drive, touch the static-protective
   package containing the drive to a metal expansion-slot screw or
   other unpainted metal surface on the computer, for at least 2
   seconds. (This drains static electricity from the package and your
   body.)

 9 When possible, remove the drive and install it directly into the
   computer without setting it down. If this is not possible, place
   the drive, component side up, on the static-protective bag on a
   flat surface until the drive is installed.

 10 Do not place the drive on the computer cover or on a metal table.


 Installing the drive
 --------------------
 These instructions guide you as you install the drive inside your
 computer or storage enclosure.

 Step 1. Setting the jumpers and terminators

 Note: Be sure you have chosen the SCSI ID before continuing. If you
       did not yet choose the SCSI ID, go to "SCSI IDs" above, then
       return here. Follow these steps to set the SCSI ID to match
       your chosen SCSI ID.

 1 Touch the static-protective bag containing the drive to a metal
   expansionslot cover on the computer. This drains any static
   electricity from the package and your body.

 2 Remove the drive from the static-protective bag, holding the drive
   by the edges. Do not touch any exposed components on the drive.

 3 Place the drive on the bag, on a flat surface.

 4 When the Auto Start feature is enabled, the hard disk drive motor
   starts as soon as the computer is turned on. Locate the Auto Start
   jumper by referring to the documentation that came with your drive.
   If the Auto Start jumper is not in place, the hard disk is started
   by a command from the SCSI controller. For drives installed in
   IBM computers or storage enclosures ensure that this jumper is off.
   The hard disk drive is started in a staggered sequence. This
   reduces the start-up load on the power supply. For non-IBM
   computer, refer to the documentation that came with your
   computer for further information.

 5 Set the SCSI ID that you selected. To remove a jumper, pull it
   straight off. To install a jumper, line up the two holes in the
   jumper with the appropriate two pins on the drive. Then push the
   jumper onto the pins until it is completely seated and covers
   both pins.

 6 Store any jumpers you do not use in a safe place, in case you need
   to change the SCSI ID for this drive later. WARNING: If you have
   extra jumpers, do not store them on any of the extra pins on the
   connector. Storing them on a set of pins could damage the drive.

 Step 2. Connecting the terminator
 The location of the drive you are installing inside the computer or
 storage enclosure determines whether you need to connect a terminator
 or put a jumper on the Enable Active Termination pins. Read the
 information in the following table to determine if you must install
 the terminator. For more information about termination, refer to the
 documentation that came with your computer.

 Note: A SCSI chain of devices consists of multiple SCSI devices
 connected by a SCSI cable to a SCSI controller.

 If the hard disk drive is:                   Then:
 The last physical device on a SCSI chain of  Install the terminator
 devices inside the computer.

 The last physical device on a SCSI chain of  Install the terminator
 devices inside an external storage enclosure.

 Step 3. Enabling term power
 If your drive has a jumper for term power and your SCSI controller is
 suppling term power, (check with the manufacturer of your controller)
 then you do not need to enable the term power. The jumper should be
 off. For help in locating the term power jumper, refer to the
 documentation that came with your drive.

 Step 4. Installing the drive
 For the specific information on installing a hard disk drive, refer
 to the documentation that came with your computer. You will be
 required to mount the drive inside your computer, and connect signal
 and power cables to the hard drive. When installed in an enclosure,
 the drive is attached by cable to the external connector of a SCSI
 controller. The controller can be either on a SCSI adapter or built
 into the system board inside of your computer.

 Note: Be sure to use the correct screws provided with your drive.
 Using the wrong ones might cause damage to the drive.

 Step 5. Completing the installation procedure
 The installation of the drive is complete. Reinstall the cover on the
 computer or storage enclosure. Store these instructions and any extra
 parts in a safe place in case you change your configuration.

 After installing your hard disk drive, use the information that came
 with your computer to reconfigure your system. When you power on your
 system, turn on all attached devices first; then turn on the
 computer.

 If you have any problems at this point, turn off all attached
 devices; then, turn off the computer and check that:

 1 The cables are installed correctly

 2 No options or cables are loose

 3 The SCSI ID is properly set

 4 No two SCSI drives have the same SCSI ID

 5 The terminators are properly installed

 Turn on all attached devices; then, turn on the computer. If you
 still have a problem, refer to the troubleshooting information in the
 documentation that came with your computer.

 Step 6. Update configuration
 Whenever you add or remove an option from your computer, you must
 update the configuration information. Your computer might have an
 automatic configuration program, or you might have to follow a
 specific procedure. For more information, refer to the documentation
 that came with your computer.

 Step 7. Preparing the drive for use
 Having successfully installed the hard disk drive, you need to
 prepare it for use. Depending on the operating system you are using,
 you might need to partition then format the hard disk. Refer to the
 documentation that came with your operating system for information on
 how to format your new drive. To make the drive just installed your
 primary drive, you might need to create a new system partition on the
 drive. For information on creating a new system partition, refer to
 the documentation that came with your operating system.


 Troubleshooting
 ---------------
 You might be able to solve a problem yourself. Before calling IBM,
 you might want to try some or all of the following troubleshooting
 procedures.

 1 Remove and reattach all drive cables

 2 Remove and reseat the drive

 3 Place the drive in a different slot, if one is available


 4 If your drive contains jumpers or switches, check that they are set
   as specified

 5 Reread any software instructions; be sure software settings are
