 Drive configuration
 -------------------
 You can easily install your new Seagate disc drive as your first ever
 hard drive, a replacement or as a second drive in a computer system
 with an existing hard disc drive.

 Installation involves the following steps:
 - Drive configuration

 - Mounting

 - Informing the computer about your drive and how you want it divided
   into partitions.

 Before you physically mount your new disc drive in your computer, you
 need to check the jumper plug settings that determine how the drive
 operates.

 Note that there are some connector pins sticking out from the drive's
 printed circuit board (PCB) that are labeled J2 and J6 (called
 "jumper plug headers").

 Model "W" additionally has J1-Auxiliary. Some systems may have a
 cable connected to J1-Auxiliary that allows remote setting of drive
 ID by switches or within the computer logic. It also provides a
 connection to a remote drive activity LED. Jumpers may be used on
 J1-Auxiliary.

 Note the small jumper plugs connected across pairs of pins in some
 places on these connectors.

 Caution. Note that the jumper plugs used on J2 are shaped differently
 and are smaller than those used on J6 or J1-Auxiliary. Do not use J2
 plugs on J6 or J1- Auxiliary as this will damage the internal
 contacts so they will not subsequently stay on J2. The presence or
 absence of these jumper plugs in various places gives your drive
 information about how it is to operate in your system specifically.

 If this is your first hard drive, or if it replaces your existing
 hard drive, you may not need to reposition any jumpers. However,
 check the figures against your drive to see if it is configured as it
 should be for your system. Consult your computer documentation for
 information on configuring your drive. Your dealer is the best source
 for help on this. Seagate also provides support service for customers
 if your dealer can't help.

 Set Drive ID
 ------------
 If your new drive will be the only hard drive, assign it as "Drive ID
 0," which requires no drive ID jumpers installed. If your new drive
 is to be a second hard drive, assign it as "Drive ID 1" by placing
 one of the extra jumper plugs supplied in the enclosed plastic bag
 (one of the larger plugs) on the "Drive ID 1" position. Double check
 drive ID settings for your drive or drives.


 Select Operating Features
 -------------------------
 If your new drive replaces an existing drive, you must set up the new
 drive to operate as the old drive did. Check the documentation for
 your old drive to see how the drive was set to operate. Normally,
 you should leave off the "Delay Motor Start", "Enable Motor Start,"
 "Write Protect", "Parity Disable" and "Term power to SCSI Bus"
 jumpers. A jumper on means the feature is enabled, except for "Parity
 Disable," where a jumper on means that parity checking is disabled.
 Only "Terminator Enable" and "Term Power from drive" jumper positions
 should have a jumper on ("N" and "W" models only). Do not remove
 these two default jumpers or add jumpers to any of the other jumper
 positions mentioned above unless your computer system documentation
 indicates otherwise.

 The factory installed default settings are generally always correct.

 Drive model "WC" plugs directly into a bulkhead or PCB mounted
 connector. Systems using these drives have made provisions for
 terminators and selecting most options, so only "Write Protect" and
 "Parity Disable" options (on J2) must be considered for possible
 setting by a person installing a replacement drive (usually no change
 is needed). Most systems using "WC" model drives use drives that
 have unique drive internal control firmware, so "off the distributor
 shelf" drives probably will not work in these installations.

 Firmware cannot be changed on these drives. If you are upgrading by
 installing an additional drive, consult the system documentation or
 system purchase source for help in setting up drive ID, options and
 getting termination correct.


 I/O line terminators
 --------------------
 The SCSI I/O lines must be "terminated" at the drive connected to
 the end of the cable. If your new drive is a model "N" or "W" and is
 to be connected at the end of the cable, a jumper plug should be
 installed on J2.

 On J2, the "Terminator Power" (TP) jumper should be left in the
 "Term. Power From Drive" position, unless otherwise directed by your
 computer documentation.

 If your drive is to be connected at the cable connector that is not
 at the end of the cable (it is a second hard drive for your system),
 the "Terminator Enable" jumper should not be installed. Remove and
 store the jumper if there is one on the "Terminator Enable" position.

 If installing a "WC" model drive see system documentation. "WC"
 drives have no terminators, nor do they furnish terminator power to
 the I/O bus. Terminators are in the Host system.

   |                 |
   +-----------------+

 The drive will operate in all axis (6 directions).

 Things you may need to install the drive
 ----------------------------------------
 - Adequate power from your computer power supply This drive requires
   7.5 watts during typical operation, and 6.0 watts when at idle (not
   reading, writing or seeking). If this drive is an "add-on" make
   sure the computer power supply can supply enough extra power for
   this drive's needs.

 - An antistatic wrist strap You will need this to reduce the
   possibility of damaging your drive by static discharge.

 - A #2Phillips screwdriver You will need this screwdriver to open
   your computer and to insert the drive mounting screws.

 - A Torx Size TX-08 driver tool If your drive has a front panel and
   you need to install the drive in a conversion frame kit, this tool
   will be needed.

 - A bootable DOS system diskette for the PC
   You will need this diskette, which should contain the DOS system
   files and the programs FDISK.EXE and FORMAT.EXE to partition and
   format your new hard drive.

 - A SCSI host adapter card for the PC You may need this if your
   computer does not already have a hard drive, if your present drive
   does not connect to a SCSI host adapter, or if your present SCSI
   adapter card cannot address a drive having the capacity the Hawk
   2XL has.

   The host adapter card should have instructions with it for
   installing the card and assist in the installation of hard disc
   drives that it supports.

 - A 50-pin SCSI interface cable You will need an interface cable if
   your computer does not presently contain a SCSI hard drive. If you
   are adding a second hard drive you must use an interface cable that
   has two drive connectors, one on the end and one in the middle.


 - A Y-shaped drive power cable You may need this if your computer
   does not have enough power cables to supply power to your new hard
   drive.

 - Mounting screws You will need four 6-32 x 1/4 inch (6.4 mm)
   nonmetric screws if you mount your drive directly into the drive
   bay.

 - Drive mounting rails You may need drive rails if your computer's
   drive bay is not designed for direct mounting.
 - A frame kit You will need a frame kit if you wish to mount a
   3.5-inch disc drive in a 5.25-inch drive bay.

 - Extra configuration jumpers A small plastic bag of two types of
   configuration jumpers is included in drive package.


 Mounting the drive
 ------------------
 Important Precautions:
 - Make sure your computer is turned off before beginning
   installation.

 - Although switched off, your computer must remain plugged into an
   electrical outlet with an earth ground. This minimizes the
   possibility of damage from static discharge.

 - Static electrical charges can accumulate quickly on people,
   clothing and synthetic materials. The electrostatic fields due to
   these charges when brought in close proximity to susceptible
   circuit assemblies and components, can result in degraded
   reliability or immediate failure of the affected component or
   assembly.

 - Always wear a grounded wrist strap. Attach the wrist strap to the
   metal chassis of your computer. Use the antistatic pad as your work
   surface, and avoid installation in areas with static-inducing
   carpets.

 1. Begin by removing the cover of the computer. Follow the
    instructions in your computer manual. Systems that use "WC" drives
    probably do not require cover removal, as the drives are mounted
    in a module that slides into place and plugs in.

 2. Does your system have 5.25-inch drive bays?
    Your Seagate drive is designed to fit into a 3.5-inch wide drive
    bay. If your computer has 5.25-inch drive bays, then you must
    mount the drive ("N" or "W" models only) in a conversion frame kit
    before it will fit into your com-puter. Purchase a conversion
    frame kit from your com-puter dealer if necessary.

 3. Connect the 50 or 68 pin interface cable to the hard drive
    interface connector on the SCSI host adapter card. Be careful not
    to bend the pins on the host adapter card connector. Refer to your
    SCSI host adapter manual for the location of the interface
    connector.

    The sockets on the interface cable must be matched correctly with
    the pins on your SCSI host adapter interface connector. Verify
    the location of pin 1 on the SCSI host adapter using your computer
    system's manual. Pin 1 on the interface cable is indicated by the
    stripe along the edge of the cable. Plug the cable into the hard
    drive interface connector on your SCSI host adapter.

 4. Thread the other end of the interface cable through your drive bay
    and connect to the disc drive. The sockets on the interface cable
    must be matched correctly with the pins on the disc drive. Pin 1
    on the interface cable is indicated by the strip along the edge of
    the cable; pin 1 on the Seagate disc drive is the pin closest to
    the HDA, on the side closest to the four-pin power supply
    connector. Plug the interface cable into the drive connector
    firmly but carefully. The connector should cover both rows of
    pins.

    If you are installing a second or multiple disc drives, repeat
    this procedure using the additional drive connectors on the
    interface cable.

 5. Mount the drive in a drive bay.
    - Direct mounting: The disc drive can be mounted in the drive bay
      in any orientation permitted by the drive bay mechanical
      configuration. Be careful not to over tighten the mounting
      screws. Screws must not extend into the side drive mounting
      holes more than 0.015 inches, (9/64 inches) or into the bottom
      mounting holes 0.20 inches (3/16 inches). Purchase the four
      required 6-32 x 1/4 inch screws at a hardware or drive supplier
      store.
    - Using drive rails: In some computers, you must attach drive
      rails to either side of the drive, then slide the drive into
      the drive bay on its drive rails. Be sure that the drive is
      securely mounted within the bay. In computers that do not use
      drive rails, screw the drive or the frame kit holding the drive
      directly to the drive bay.

   - Using a conversion frame kit: To mount a 3.5" drive in a 5.25"
     drive bay, install the drive in the frame kit (installation
     instructions and required hardware are included with a frame
     kit). Then mount the frame kit in the drive bay. If you are
     installing two disc drives, repeat the appropriate procedure
     above for the second drive.

   - Using a special module: "WC" drives should be fitted with slides
     or most likely, mounted in a special module that slides into the
     host equipment.

   - Drive activity LED: If the drive mounts such that the drive
     activity LED does not show when the computer cover is on, the
     computer may provide for a remote LED two conductor cable to be
     used on all models. This cable plugs into J6 on the front of the
     drive.

     "WC" model drives have a line available in the J1-80 pin
     interface. Check system documentation to see if J1 signal is used
     or if a cable should be attached to J6.

 6. Attach a system power cable to the power connector on each drive.
    If your system does not have an extra power cable for the hard
    drive, you can purchase a Y-shaped power cable, such as the one.

 7. Review each of the previous steps to verify that you have
    completed the installation correctly.

 8. Replace the cover on your computer.

SEAGATE  ST32151/31051N/W/WC  INSTALLATION GUIDE

 Before you begin
 ----------------
 Verify that the system is switched off but remains connected to the
 main power before any installation is attempted.

 Protect yourself, the drive, and your valuable programs and data by
 reading the following cautions and warnings.

 - Do not tamper with sealed top cover. Doing so voids your warranty.
   The drive contains no user serviceable compo-nents. See Product
   Repair section for more information.

 - Visually inspect the shipping container for any obvious damage.

 - Verify all parts listed on shipping bill are received with the
   equipment. Discrepancies or damage should be reported to the
   shipping company.

 - Inspect drive for possible shipping damage. All claims of this
   type should be filed promptly with the transporter involved. Save
   original packing materials to be used when reshipping.

 - When transporting or shipping a drive or system, please ensure that
   they are correctly packed in original Seagate approved (or
   equivalent) container and shipped via an airride carrier
   experienced in handling computer equipment.

 - Do not unpack drive from its static shielded bag until you are
   ready to install it in the system.

 - Always handle the drive by the frame or casting.

 - Do not touch Printed Circuit Board (PCB) or the I/O connector pins.

 - Never apply pressure to the PCB or to the drive top cover.


 Configuring the computer for your drive
 ---------------------------------------
 The hardware part of your installation should now be complete.
 Software installation informs your computer operating software about
 your Seagate disc drive characteristics. You can then divide your
 drive into partitions called "logical drives."


 DOS Installation
 ----------------
 To install your Seagate disc drive in your computer software, your
 computer operating system should be Microsoft DOS version 4.0 or
 higher. Your SCSI adapter card must be able to address greater than
 two gigabytes.

 If you already have a hard disc drive on your computer and you are
 installing a second drive, now is a good time to evaluate the status
 and quality of your backups. Once you are satisfied with the status
 of your backups, then proceed.

 Caution. Determine which drive is to be partitioned in a two drive
 system.

 - Turn your computer on and boot-up from your existing hard drive or
   from a diskette in drive A, whichever is applicable. Watch the
   screen for text that tells which key(s) to press to branch into the
   system setup program. Hit CTL-ALT-DEL to boot-up again if you
   missed it. Choose to go into setup.

 - Setup presents a menu. Choose the menu item that asks you to
   declare the drive type. If the screen says the drive type is "not
   installed" or something similar, save that and leave setup. If it
   asks you to enter a drive type, enter "none," "drive not
   installed," "type 0" or whatever similar response is given as a
   choice on the menu.

 - Save and leave this screen. The computer will probably boot up
   again. If not, hit CTL-ALT-DEL.

 - At the C> prompt or A> prompt, run the FDISK utility program
   either from your existing hard drive or from a diskette in drive
   A. (refer to your DOS user's Reference Manual for more detailed
   instructions on FDISK procedures).

 - A menu comes up that gives choices pertaining to installing your
   new drive and dividing it into partitions. If the drive you set the
   jumpers for is Drive ID 0 (no ID jumpers on), the menu will stay
   at the top, "Current fixed disk drive: 1"

 - From the menu choose "Create a DOS partition..."

 - Proceed to set up desired partitions.

 - If your new drive is jumpered as Drive ID 1, choose "Select next
   fixed disk drive" on the menu. FDISK displays the main menu again,
   but at the top it says "Current fixed disk drive: 2".

 - The menu displayed gives you the same opportunity as mentioned
   above to partition your second drive as several logical
   (simulated) drive volumes.

 Caution. Do not try to change the partitions set up for an existing
 inuse drive. If you change any partitions or logical (simulated)
 drive assignments on your existing drive, you will lose all data
 stored. Always backup the existing drive's data on diskettes, tape,
 or other media before changing the drive's configuration.

 The first hard drive (drive jumpered as ID 0) is always called drive
 C. If you already have a hard drive, FDISK shows it as drive C and
 shows if it has been divided into a primary DOS partition and an
 extended partition. The extended partition can be divided into
 several logical drives. FDISK lists these logical drives as D, E, F,
 etc. The primary DOS partition has the operating system on it (this
 is the start up or "Boot-up" partition). From the main menu, choose
 to set "Active" the DOS partition you want to boot from, which is the
 primary DOS partition.

 Many people like to make drive C a few megabytes, devoted almost
 entirely to the operating system (DOS or other) and little else.

 They put other programs on other logical drives, grouped in
 categories that provide a distribution of data and programs across
 all logical drives that suits their applications. When satisfied with
 the set up as instructed in the menus presented, reboot the drive.


 Formatting
 ----------
 Caution.
 Do not format the existing drive that contains user data that you
 don't want to lose, as all user data will be lost when a drive is
 formatted.

 When a second drive is installed, the drive letters assigned by DOS
 to the first drive may change. Be careful not to accidently format a
 logical drive with existing data.

 When you complete drive partitioning, you need to high-level format
 every new logical drive you have set up. If your new drive is to be
 the boot-up drive, insert the DOS system diskette in drive A and type
 at the A/> prompt FORMAT C: / s/v. This formats drive C and puts the
 programs on that are necessary to boot the computer from the C drive,
 and verifies that the format was performed correctly. For each
 additional logical drive you have changed or newly set up, type in
 FORMAT X: /v (where "X" is the proper drive letter for the drive to
 be formatted).


 Note: Seagate Technology assumes no liability for lost user data.
 From the C/> prompt, try to switch to each logical drive (C:, D:, E:,
 etc.) to see if you can get a prompt for each logical drive (C\>,
 D\>, E\>, etc.). With each prompt that you select, type CHKDSK. This
 shows if the logical drives are usable for storing data and programs.

 If the logical drives you set up are not recognized, try the FDISK
 set up routine and FORMAT again. You may have made a small mistake at
 some point in the installation procedure.

 Make sure that the total capacity shown for your new drive is equal
 (or close to) the formatted capacity given in the Product Information
 table, column B at the end of this guide. If not, you may need to get
 a newer SCSI adapter card that allows you to access the complete
 drive.

 If the complete DOS operating system software is not on your primary
 DOS drive (usually C), read it in from diskettes on drive A.


 Macintosh installation
 ----------------------
 To configure this drive in a Macintosh system, you must use a
 third-party hard disc initialization application. Most software
 vendors and computer stores that carry Macintosh software will have
 hard disc drivers available for purchase.

 Follow the instructions provided with the disc initialization
 application to complete the installation of your Seagate drive.

 Note. The Apple HD SC Setup utility included with your Macintosh
 system software only works on drives or-dered directly through Apple.


 Unix installation
 -----------------
 There are several versions of the Unix operating system. Each of
 these handle hard disc installation in a different manner. For this
 reason, refer to your system's operation manual for information about
 how to complete the installation of this disc drive. Contact Seagate
 Technical support services for any additional information needed to
 install the drive in a Unix system.

 Troubleshooting
 ---------------
 Before calling Seagate Technical Support, please read and consider
 the possibilities discussed below. The suggestions presented here
 will resolve the majority of installation problems.


 General installation troubleshooting
 ------------------------------------
 - Check system compatibility. This is a SCSI interface device. Check
   your system documentation to ensure that is supports SCSI
   interface devices.

 - Check the drive ID assigned. Model "N" has three drive ID jumper
   positions on the drive.

 - Check the drive operating feature jumpers.
 - Check to ensure that drive is receiving power. Insert the drive
   into your system. Listen carefully for the sound of the drive motor
   spinning up. There should be the rotational spin up noise, with no
   interruption, followed by seeking noises and clicks. If the drive
   motor does not spin up, check the power supply. If your power
   supply is functioning properly, but the drive does not spin up,
   contact the company from which you purchased the drive. If you have
   added one or more drives to your existing system the power supply
   may not be able to furnish enough power. Check with your drive
   purchase source about this.

   Inadequate power supplies may work for a short period of time under
   great stress, and then either fail or operate in a severely
   degraded mode. It may supply enough +5 V for the logic to respond,
   but not enough current on the +12 V for a spinup.
