 Install master/slave jumpers
 ----------------------------
 In a two-drive system, you need to designate one drive as the master,
 or drive 0, and the other drive as the slave, or drive 1. To do this,
 install the master/slave jumpers. In a one-drive system, configure
 the drive as a master (no jumpers installed).

 Alternatively, you can configure the drive as a master or slave using
 the cable select option. Cable selection requires a special daisy-
 chain cable that grounds pin 28 (CSEL) on one of its two drive
 connectors. If you attach the drive to the grounded CSEL connector,
 it becomes a master.

 If you attach the drive to the ungrounded CSEL connector, it becomes
 a slave. To use this option, the host system and both drives must
 support cable select, and both drives must be configured for cable
 select. To configure a Marathon 810 for cable select, install both
 master/slave jumpers.

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


 Mounting the drive
 ------------------
 Mount the drive securely in the computer using M3X0.5 metric screws
 in the four bottom mounting holes or the four side mounting
 holes. You can mount the drive in any orientation. Be careful not to
 strain or crimp the interface/power cable.

 Caution. To prevent damage to the drive:

 - Be careful not to bend the drive connector pins, especially
   when plugging the drive into a fixed connector.

 - Use mounting screws of the correct size and length.

 - Gently tighten the mounting screws do not apply more than 3 inch-
   pounds of torque.

 - Do not insert mounting screws more than 0.15 inch.

 Note. This drive meets industry-standard MCC mounting specifications.
 When installing this drive in a fixed-mounting application, you must
 use MCC-compatible connectors and mounting hardware. If the mounting
 holes in your computer do not line up with the mounting holes on the
 drive, your computer may not be MCC-compatible.

 Attaching cables
 ----------------
 This drive is designed for a host computer that supplies interface
 signals and +5V power through a single 44-pin connector and cable. If
 your computer has a fixed connector that attaches directly to the
 drive, skip ahead to the following section,

 - Mounting the drive.
 - Otherwise, attach the interface/power cable as described below.

 1. Turn off the computer and remove the battery.

 2. Put on a grounded wrist strap.

 3. Open your computer case. See your system manual for instructions.

    Caution. Opening the case may void your computers warranty.

 4. Connect the 44-pin interface/power cable. Match pin 1 of
    the cable to pin 1 of the interface connectors on the drive and
    on the computer. Pin 1 is usually denoted by a stripe along
    one edge of the cable.
    The cable should be no longer than 18 inches (0.457 meters).

    Caution. The printed-circuit cables used in laptop computers
    are very delicate. Be careful not to tear them.

SEAGATE  ST9816AG  INSTALLATION GUIDE

 Application
 This drive uses the ATA interface and is designed for IBM AT and
 compatible personal computers. It is intended for use with UL-listed
 computers or similar products.

 Note. DOS systems are not able to access more than 528 Mbytes on a
 single drive unless:
 1) the host system supports and is configured for LBA addressing or
    for extended CHS addressing, or

 2) the host system contains a specialized drive controller, or

 3) the host system runs BIOS translation software. Contact your
    computer dealer for details.

 Warning. Turn off the computer (and remove the battery if you have a
 notebook or laptop computer) before you open the case or touch any
 internal components.

 Caution. Special training or tools may be needed to service laptop
 and notebook computers. In some cases, opening the case may void
 your warranty.


 Static discharge
 ----------------
 Observe the following precautions:
 - Before handling any components, put on a grounded wrist strap.

 - Use antistatic padding on all work surfaces.

 - Avoid static-inducing carpeted areas.

 - 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.

 - Handle the drive by its edges or frame.

 - Do not touch the I/O connector pins or the circuit board.


 Drive handling
 --------------
 The drive is extremely fragile - handle it with care. Do not attach
 labels to any part of the drive.


 Inspection
 ----------
 After you are familiar with the handling precautions listed below,
 inspect the drive. If it appears to be damaged, call your distributor
 or dealer immediately.


 Maintenance and repair
 ----------------------
 Seagate drives do not require maintenance.
 The head/disc assembly is sealed; if you break the seal, you void the
 warranty. Seagate customer service centers are the only facilities
 authorized to repair Seagate drives. Seagate does not sanction any
 thirdparty repair facilities.


 Configuring the drive
 ---------------------
 1. Put on a grounded wrist strap. Wear the grounded wrist strap
    throughout the installation procedure.

 2. Install master/slave jumpers.


 Configuring your computer
 -------------------------
 Many newer computers can automatically determine your drive type and
 configure themselves appropriately at startup. Read your system
 manual to determine whether this applies to your computer. If your
 computer supports drive autodetection, skip ahead to Formatting and
 partitioning the drive below.

 Note. DOS systems are not able to access more than 528 Mbytes on a
 single drive unless:
 1) the host system supports and is configured for LBA addressing or
    for extended CHS addressing, or

 2) the host system contains a specialized drive controller, or

 3) the host system runs BIOS translation software. Contact your
    computer dealer for details.

 If your computer cannot automatically determine your drive type,
 you must run a system setup program to specify the number of
 cylinders, heads and sectors for each drive in your system. This
 procedure is described on the following pages. The table below
 lists cylinder, head and sector information for the Marathon 810.

 Cylinders             1,571
 Heads                    16
 Sectors per track        63
 Total sectors         1,583,568
 Bytes per sector        512
 Capacity (Mbytes): BIOS calculated capacity 773 - Usable capacity
                                                   810.7


 To enter drive specifications into your system BIOS, follow these
 steps:

 1. Turn on your computer.

 2. Run the system setup program. This program configures the system
    BIOS to recognize your drive. In some computers you run the system
    setup program by pressing special keys while the computer is
    booting up. In other computers, you can run the program from the
    DOS prompt. See your system manual for more information.

 3. Enter your drive specifications. Within the system setup program,
    there are three possible ways that you can enter your drives
    specifications:

 - Specify a custom or user defined drive type. Define a custom or
   user defined drive type (typically drive type 49).
   You can then enter your drive specifications.
   When you enter drive specifications for a custom or user defined
   drive type, the setup program should display a drive capacity less
   than or equal to the BIOS calculated capacity. This value is
   slightly lower than the usable drive capacity.

 - Allow your drive to emulate or translate one of the predefined
   drive types. If none of the predefined drive types exactly matches
   your drive, and your system setup program does not allow you to
   specify a custom drive type, your drive may be able to emulate one
   of the predefined drive types. Select a predefined drive type that
   has a capacity as close as possible to, but not greater than, the
   BIOS calculated capacity of your drive.
 Note. If you emulate a drive type with a lower storage capacity
 than your drive, you limit the effective capacity of your drive. For
 example, a 350-Mbyte drive emulating a 300-Mbyte drive will be
 limited to 300 Mbytes of storage capacity.

 - Select a predefined drive type. Most system setup programs provide
   a long list of predefined drive types. If possible, select a
   drive type with specifications that match those of your drive.

 Caution. Write down the drive type that you have selected and
 any drive specifications that you have entered. Keep this information
 in a safe place. You will have to reenter this data if your CMOS
 battery fails.

 The system setup program may request information on the drives write
 precomp or landing zone. However, you do not need to enter any values
 because your Seagate drive does not use these parameters.


 Formatting and partitioning your new drive
 ------------------------------------------
 Caution. Formatting or partitioning a drive that contains data may
 destroy all data on the drive. Before repartitioning or reformatting
 a drive that contains data, make sure all data on that drive has been
 safely backed up.

 Seagate Technology assumes no liability for lost data.


 Low-level formatting
 --------------------
 Seagate ATA Interface drives are low-level formatted at the factory
 and do not require additional low-level formatting before use.

 Note. If you are installing only a single drive in your computer,
 you can use the DOS program SETUP.EXE (supplied with MS-DOS 5.0 and
 above) to partition and format the drive.

 See your DOS manual for details. After you successfully run
 SETUP.EXE, your drive will be ready to use, and you can skip the
 partitioning and formatting steps below.


 Partitioning
 ------------
 The partitioning process subdivides a single disc drive into
 partitions that behave as separate logical drives (labeled C, D,
 E, etc.). You can also set up the entire disc as a single partition.

 1. Restart your computer. Boot up the computer using a diskette that
    contains DOS system files.

 2. Run the FDISK program. Insert a DOS program diskette containing
    the FDISK program into your diskette drive. At the DOS prompt,
    type fdisk and press ENTER. Then follow the directions on the
    screen to create one or more partitions. See your DOS manual for
    details. If you are partitioning a drive that will be used to boot
    the computer, make sure that the primary partition is marked
    active.


 High-level formatting
 ---------------------
 High-level formatting verifies the information written by the
 low-level format and creates file allocation tables used to catalog
 and access files.

 Caution. Make sure that you know the correct drive letter for the
 partition you want to format. Formatting a drive that contains data
 may destroy the data on that drive.

 1. Run the FORMAT program. Insert a DOS program diskette containing
    the FORMAT program into your diskette drive. At the DOS prompt,
    type format, followed by the drive letter for the first drive
    partition you want to format (for example, format C:). Then, press
    ENTER. Repeat this procedure to format each of the new drive
    partitions you have created.

    Consult your DOS manual for FORMAT command options.
    Note. If you are formatting the drive partition that will be
    used to boot your computer (the  C  drive), copy the DOS system
    files to this drive. To do this, type /s after the format command
    (for example, format C: /s).

 2. Verify the drive capacity. After high-level formatting a drive,
    you can verify the usable drive capacity by running the DOS
    CHKDSK utility program.

 Installation troubleshooting
 ----------------------------
 Before calling Seagate Technical Support, please read and consider
 all the possibilities discussed on the following pages. The
 suggestions presented here address the vast majority of installation
 problems.


 General troubleshooting procedures
 ----------------------------------
 The following is a list of general troubleshooting procedures.
 Solutions for specific problems are provided on subsequent pages.

 Warning. Always turn off the computer before changing jumpers,
 moving cables or touching any internal components.

 - Verify hardware compatibility. Check the documentation for your
   drive, host adapter and computer to confirm that these components
   are compatible.

 - Verify your hardware configuration. Check the documentation for
   your drive, host adapter and computer to confirm that all jumpers
   are set appropriately.

 - Check all cables. Make sure that all cables are securely connected.
   Printed circuit and ribbon cables are quite fragile. Check to see
   that they are not crimped or damaged. Make sure that pin 1 of the
   interface cable is connected to pin 1 of the interface connector on
   the drive and on the computer.

   Most ribbon cables have a stripe down one side to designate pin 1.

 - Check all cards. If your computer has expansion cards, check to see
   that they are inserted completely into their slots on the
   motherboard and are secured with appropriate mounting screws. Make
   sure that full-size (16-bit) cards are not plugged into half-size
   (8-bit) slots.

 - Verify the BIOS drive type. Make sure that you entered the correct
   drive type or translation geometry in the BIOS setup program. The
   drive capacity and number of sectors specified in the BIOS must not
   exceed the specifications. If the drive type is incorrect, you must
   rerun the system setup program. Then partition and high-level
   format the drive again.

 - Check for I/O address conflicts. To isolate an address conflict,
   first verify that the drive and host adapter are compatible
   with your system by disconnecting all other peripherals except the
   video card. Then install the drive and host adapter, and test the
   system. Next, install the other peripherals, one at a time, until
   the conflict reappears. After you have isolated the source of the
   address conflicts, you can resolve the conflict by changing the I/O
   address of the peripheral that appears to cause the conflict.

 - Check the power supply. The output of your power supply may not be
   sufficient to meet the power requirements of the new devices you
   have installed. If you are not sure whether your power supply meets
   your system requirements, consult your computer dealer or
   distributor.

 - Check your DOS version. You must use the same version of DOS (we
   recommend MS-DOS version 5.0 or later) throughout all phases of
   building and configuring your computer system.

 - Check for viruses. Use the latest version of a reliable virus
   checking program to scan your computer s memory, hard discs and any
   suspect diskettes for viruses. Run the virus checking program if
   you encounter inexplicable disc errors or damage to disc
   partitions. Also, before installing any new software, scan the
   installation diskettes for viruses.


 Specific Troubleshooting
 ------------------------
 Procedures Methods for resolving specific drive installation
 problems are listed on the following pages. These methods incorporate
 many of the general troubleshooting techniques described in the
 previous section.

 The screen remains blank when you power up the computer.

 - Make sure the monitor is plugged in and turned on.

 - Check all cards. Make sure the video card is seated in its slot
   and secured with mounting screws.

 - Check all cables. Make sure the video card cables (if any) are
   securely attached.

 - Power down the computer and remove the drive host adapter.
   If the screen comes on after you reboot, the host adapter may
   be incompatible or defective. If so, see your dealer.
   At startup, the computer does not recognize the presence of the
   drive.

 - Check all cables.

 - Check jumper settings on all drives.

 - Check the power supply.

 - Reboot the computer and make sure the drive spins up. If your
   drive is very quiet, you may not be able to hear it spin up. In
   this case, check the drive activity LED if your computer has
   one. If the drive does not spin up, check the drive cables again.

 - Verify the BIOS drive type.

 - Check for I/O address conflicts.

 - Try a warm boot. Press CTRL, ALT and DELETE simultaneously to
   reboot the computer without turning off the power. If a warm
   boot causes a previously unrecognized drive to become recognized,
   there may be a timing problem in which the drive fails to become
   ready before the host completes its power-on self-test.

 One possible solution is to power up your computer with its processor
 set at low speed (see your computer manual for details on setting
 processor speed). After the computer is up and running, return your
 processor to high speed or turbo mode. Another option is to warm-boot
 your computer after every power-on. You may also be able to solve
 this problem by upgrading your system BIOS.

 At startup, the message "HDD controller failure" appears.

 - Check jumper settings on all drives.

 - Check all cards and cables.

 The dealer partitioned and high-level formatted the drive for you in
 the store. Later, you installed the drive and it does not work.

 - Reboot the computer and make sure the drive spins up.

 - Check all cables.

 - Check the power supply.

 - Check your DOS version.

 Call your dealer to make sure the DOS version the dealer used to
 partition and high-level format the drive is the same as the version
 you have installed on your computer.

 - Verify the BIOS drive type. When you run the system setup program
   on your computer, you must specify the same BIOS drive type or
   translation geometry that the dealer used.

 - Check for memory conflicts.

 - Check for viruses.

 During the FDISK program, you get an error message warning of an
 attempt to write to track 0 or to the boot sector; the message may
 also suggest that a virus is present.

 - This occurs in systems having a virus protection scheme that does
   not allow programs to modify the boot sector of the disc. See your
   system manual for details. To avoid the problem, run the system
   setup program and turn off the virus-protection option. Then exit
   system setup and run the FDISK and FORMAT programs. After all drive
   partitions are formatted, use the system setup program to turn
   virus protection on again.

 During the FDISK program, the computer hangs or fails to create or
 save the partition record.

 - Check all cables.

 - The FDISK program on your DOS utilities diskette may be corrupted.
   Try running the program from a different diskette.

 - Check to see whether you are using a version of MS-DOS prior to
    version 4.0. If so, upgrade to MS-DOS version 5.0 or later.

 - Try another drive type or translation geometry. Sometimes the
   host BIOS does not accept a particular translation geometry even
   though that geometry is listed as an option during system setup.

 - Make sure that the host adapter is not assigned an interrupt
   that is already in use by another device. Modify the interrupt
   jumpers if necessary.

 During the FDISK program, the error message, "No Fixed Disk Present",
 appears.

 - Check all cables.

 - Check the power supply.

 - Reboot the computer and make sure the drive spins up.

 - Verify the BIOS drive type.

 - Check for I/O address conflicts.

 During high-level formatting, the drive keeps finding hard errors and
 reporting the following message: "Attempting to recover allocation

 - This is normal with some versions of DOS. The drive will format
   normally. However, after formatting the drive, you may want to
   run a thirdparty surface scan program to check for bad sectors.
   During high-level formatting, the drive does not format to full
   usable capacity.

 - Verify the BIOS drive type. Your drive s formatted capacity is
   limited to the capacity of the BIOS geometry you selected. If
   your BIOS does not offer a geometry that takes advantage of
   the full capacity of the drive, and a user-defined drive type is
   not available, use a third-party partitioning utility.

 - Run FDISK again and make the partitions smaller. Make sure
   you are using MS-DOS version 5.0 or later or equivalent.

 At startup, the messages, "Disk Boot Failure", "Non-System Disk", or
 "No ROM Basic - SYSTEM HALTED", appear.

 - Run the FDISK program and make sure the primary partition is marked
   active.

 - Check all cables.

 - Check your DOS version.

 - Reinstall the DOS system files onto the hard disc using the SYS
   command (see your DOS manual).

 - Check for viruses.


 During operation, the system error message, "Drive not Ready",
 appears.

 - Check all cables.

 - Check the power supply.

 - Reboot the computer and make sure the drive spins up.

 Compatibility notes
 - The Marathon 810 conforms to the ATA interface specifications.
   The host system BIOS must provide support for the ATA interface
   command set. For a detailed description of the ATA commands
   implemented by this drive, see the Seagate Marathon 810 Product
   Manual and the Draft Proposed ATA-2 Standard.

 - In accordance with ATA specifications, the system BIOS must reset
   any emulation/translation parameters after a hard reset.

 - In some configurations, a Marathon 810 may supply up to 16 bytes of
   error correction code (ECC) with the Read Long and Write Long
   commands. Depending on the drive type, your system BIOS may look
   for 4 bytes of ECC. If your system BIOS expects 4 bytes of ECC and
   the drive supplies a different number of bytes, some drive
   diagnostic programs may fail, typically resulting in timeout
   errors. Consult your computer documentation or call your computer
   dealer or manufacturer for information on configuring your computer
   to receive more than 4 bytes of ECC.

 - Some older drive diagnostic programs may incorrectly report an
   ECC-detection failure when analyzing a Marathon 810. This occurs
   because the drive hardware corrects the data automatically,
   avoiding the error rather than reporting it. Such a report does not
   indicate a drive malfunction.
