Western Digital  (250-0105/6) Installing the Drive     Faxback Doc. # 15666
Hard Disk Upgrade Kit       With Ontrack Disk Manager

You need a bootable DOS diskette to install Ontrack Disk Manager if your
new Western Digital hard drive will be installed as your master C: drive. 
If you don't have a bootable DOS diskette, you can create it by following
these steps:

1.  Insert a blank diskette into drive A.

2.  Type:  format a:/s.  Press ENTER.

Most computer systems provide a CMOS setup program that allows you to
access information regarding your system configuration.  This information
must be modified to include the exact parameters of your new Western
Digital hard drive.

Follow these steps to use the CMOS setup program provided with your
computer system:

1.  Insert a bootable DOS system diskette into drive A: and turn your
    system on.  If you are installing your new Western Digital hard drive
    as the slave drive (D:), boot your system from the C: drive.

2.  Go to your CMOS setup screen.  Refer to your system manual for
    instructions.  If you have an existing drive, write down the hard drive
    type and parameters (cylinders/heads/sectors) for the existing drive. 
    Do not change the hard drive parameters of your existing hard drive at
    this time.

Some system setup programs offer a "User Defined" or "Auto Config" hard
drive type.  The User Defined hard drive type allows you to define the
hard drive parameters, while the Auto Config drive type automatically sets
up the hard drive parameters by interrogating the Western Digital hard
drive directly.

HOW TO DETERMINE IF YOUR SYSTEM SUPPORTS DRIVES WITH A CAPACITY GREATER
THAN 528 MB

If you are installing a hard drive with a capacity over 528 MB, your
computer system may or may not support its full capacity.  All computer
systems manufactured prior to 1994 do not support hard drive capacities
over 528 MB unless the system BIOS has been updated.  An easy way to check
this is to turn on your computer and read the first screen carefully.  Most
systems display BIOS information with a date.  If the date displayed is
prior to 1994, then your system most likely WILL NOT support drive
capacities over 528 MB.  You can also call your system manufacturer to
obtain this information.

IMPORTANT:  528MB = 1024 cylinders, 16 heads, and 63 sectors.

If you have determined that your system will not support drive capacities over 528 MB, you have two options:

1.  Install the enclosed Ontrack Disk Manager software.

2.  Contact your system or BIOS manufacturer and obtain an updated BIOS
    that will support your drive.  This is usually referred to as a
    "translating BIOS" or "Enhanced IDE BIOS."

Some of the more common BIOS manufacturers and their phone numbers are:

    - AMI                          (404) 263-8181
    - Award                        (415) 968-4433
    - Micro Firmware (Phoenix)     (405) 321-8333
    - MR BIOS                      (508) 686-6468
    - Phoenix                      (617) 551-4000

IMPORTANT:  A translating BIOS supports drives greater than 528 MB (1024
           cylinders, 16 heads, and 63 sectors).

If you choose to update your BIOS, refer to "Selecting Hard Drive
Parameters For Systems with a Translating BIOS" after installing your new
BIOS.

HOW TO VERIFY IF YOUR COMPUTER SYSTEM MANUFACTURED IN 1994 OR LATER WILL
SUPPORT YOUR DRIVE

To verify if a system manufactured in 1994 or later has a translating BIOS,
and therefore can support your drive, we suggest the following:

1.  Contact your system or BIOS manufacturer and verify that your system
    supports hard drive capacities over 528 MB.  This is usually referred
    to as a "translating BIOS" or "Enhanced IDE BIOS," or

2.  Enter your CMOS setup program and look for setup options such as "LBA",
    "Large Disk Access", or "Translation."  Be sure to enable these
    options.

If you have determined that your system WILL support hard drives over 528
MB, we recommend that you DO NOT install Ontrack Disk Manager software. 
Select your hard drive parameters in the CMOS setup program as explained in
the following section.

If you have determined that your system has a translating BIOS, and
therefore can support drives over 528 MB, follow these steps:

1.  Go to your CMOS setup screen.  Refer to your system manual for
    instructions.

2.  Select the Hard Disk Type option for the new Western Digital hard
    drive.  Select "Auto Config."

3.  Verify that any options such as "LBA", "Large Disk Access", or
    "Translation" are enabled.

    NOTE:  Most systems have translations enabled only when "Auto Config."
           is selected.  If the "Auto Config." option is not available,
           consult your operating system manual.

4.  Save the changes, exit the SETUP program, and restart the computer.

NOTE:  Western Digital and CHKDSK define a megabyte as 1,000,000 bytes. 
       CMOS setup and some utility software programs define a megabyte as
       1,048,576 bytes.

Your version of DOS determines how you partition your drive(s).

    MS DOS and PC DOS versions 5.0 and later automatically partition and
    format the drive during DOS installation, without requiring your to
    manually run the FDISK and Format utilities.

    If you have MS DOS version earlier than 3.3, you can only address 32 MB
    maximum on your drive.  You cannot partition the drive without third
    party software.  We recommend you upgrade to MS DOS 3.3 or above.

    If you have MS DOS versions 3.3, DOS allows you to partition larger
    drives into logical disk drives with a maximum of 32 MB per partition.

    If you are working with MS DOS version 3.31 or greater, you can
    partition a disk drive to the maximum size of the drive.  You are not
    limited to 32 MB.

    Some non-Microsoft versions of DOS may allow larger partitions than
    those mentioned here.

FDISK.COM automatically assigns drive IDs to the partitions.  Refer to
your operating system manual for more information on partitioning drives.

You only need to manually partition your drive(s) to overcome the
limitations of your MS DOS version.  Partitioning allows you to divide your
drive into multiple partitions, which function as separate drives.  Use the
MS DOS FDISK.COM utility to display a series of menus that help you
partition your hard drive for MS DOS.

A brief set of instructions follow.

1.  Insert your MS DOS system diskette into drive A.

2.  Reboot the system by simultaneously pressing CTRL, ALT, and DEL.  Make
    sure that the MS DOS diskette with FDISK.COM (located on the diskette)
    is inserted in Drive A.

3.  Type FDISK at the A:prompt.  Press ENTER.

4.  Follow the default options.  For more information, refer to your MS DOS
    manual.

MS DOS versions 3.3 and higher allow you to create a primary partition,
create an extended partition, change the active partition, delete a
partition, and display partition data.

REPLACING AN EXISTING (SINGLE) DRIVE

You only need to manually format your drive when you have an older version
of DOS.

Newer versions of DOS automatically format during DOS installation.  You do
not need to low-level format.

ADDING THE CAVIAR AS A SECOND HARD DRIVE

You always need to use FDISK and FORMAT utilities on the second hard drive.

When using FDISK, make sure that you have selected the second drive.  Do
not delete any partitions that already exist on the first drive.  Doing so
will result in lost data.

When using FORMAT, make sure that you select the proper drive letter in the
FORMAT command line.  Format the next drive letter after your last existing
partition.

FORMATTING A PARTITION THAT ALREADY CONTAINS DATA WILL RESULT IN THE LOSS
OF THAT DATA.

If you designated other drives or partitions during the FDISK.COM routine,
you must format those drives as well.

For example, type FORMAT D: at the A: prompt and then press ENTER. 
Continue the format process until you have formatted all drives.  When the
formatting process is complete, the D hard drive should be ready for use. 
For more information on formatting, refer to your operating system
documentation.

Booting the System

After you have properly installed DOS on the C: drive or formatted the D:
drive you are ready to use the computer.  Boot the system from the active
operating system drive, usually C.  Be sure to remove any diskettes from
drive A before booting.  To boot the system:

1.  Simultaneously press CTRL, ALT, and DEL.

2.  The system should respond and the monitor should display C> after you
    have entered the current data and time.

Refer to your system documentation for more information on booting the
system.

If the system will not boot, or if you are unable to access the new drive,
refer to your operating system documentation.  Verify that you ran the
system utilities correctly, specified the correct drive tables, designated
an active partition, and partitioned and formatted the hard disk correctly. 
If your system still won't boot, you may have improperly installed or
connected the drive.
