You must configure the computer to recognize the full
capacity of your drive. If your BIOS cannot access the full
capacity of the drive and you choose to use Disk
Manager, you can leave the hard drive parameters you
used for transferring the software file in Setup. Go to
Section 4A “Installation with Disk Manager Software.”
Disk Manager will install its software driver, Dynamic
Drive Overlay (DDO), to make the drive’s full capacity
available.

If your BIOS can accept more than 528 Mbytes, use the
steps below to configure the BIOS. Many BIOSs use
logical block addressing (LBA) mode to access drives
with capacities greater than 528 Mbytes. Check your
documentation for this feature.

1 Turn your computer on and enter Setup.

2 Enable LBA mode if it is available.

3 Locate the hard disc configuration settings.

4 If your Setup has an Auto option, select it. Save and

exit Setup. The computer automatically determines
the drive parameters and configures Setup.

If there is no Auto option and LBA mode is enabled,
select user-defined or custom, and enter the LBA
parameters shown for your drive in the table. If Setup
does not accept all of the LBA parameters,

The options jumper block, shown in the drawing below,
allows you to configure the drive to work in your system.
The default factory configuration allows the drive to
operate as a single drive attached to the hard disc
controller or as the master drive with an
ATA-compatible slave. You can configure the drive to be
the slave, to be the master with a non-ATA-compatible
slave, or to work in systems that use cable select.

The drawing below shows the available options and how
to configure the drive. A brief description of the options
is provided on the back of this poster.

To make a bootable diskette and transfer the files:

1 Turn your computer on and enter Setup. See your

computer or motherboard reference manual for
instructions on how to enter Setup. It may be called
System Setup, BIOS Setup or CMOS Setup.

2 Locate the hard disc configuration settings.

3 Select user-defined or custom, and configure the

drive for 615 cylinders, 4 heads and 17 sectors
(Drive-type 2). Save and exit Setup.

4 Immediately insert your DOS diskette into Drive A.

5 At the A prompt, type format a: /s and press 

ENTER

.

The /s switch makes the new diskette bootable.

6 The computer reads the DOS diskette and prompts

you to insert a blank diskette into Drive A when it is
ready to format the new diskette.

7 When the format is complete, reboot the computer

with the new diskette.

8 Access the prompt assigned for your new Seagate

drive.

9 Type seamove. Seamove transfers the files from the

drive to your diskette. It erases the partition and the
files when the transfer is complete. We refer to this
diskette as the Seagate software diskette.

The factory creates a partition on the drive and stores
free software files that 1) allow your computer to access
the drive’s full capacity when the 528-Mbyte barrier is
imposed; 2) you can use to partition and format the
drive; and 3) allow you to display some of the features
available on an attached ATA drive. You must transfer the
files to a blank, bootable diskette in Drive A before you
partition and format the drive. A transfer program,
Seamove, is provided to transfer the files and prepare
them for use. Seamove also erases the partition when the
transfer is complete. The software programs are:

SEG32BIT.386. A replacement 32-bit disk access driver
for Windows 3.1 that provides full 32-bit disk access
mode support for drives with capacities greater than 528
Mbytes in Windows.

Disk Manager. Installation software that partitions and
formats your drive and installs a software driver to
surpass the 528-Mbyte barrier if necessary.

DRVINF11. A program that reads an installed ATA drive
and displays the drive’s major features.

Seamove. Transfers the above software programs to a
diskette in Drive A and erases the factory partition and
format after the files are transferred.

1 Boot your computer with the Seagate software

diskette. This is a precaution to ensure that the Disk
Manager installation does not conflict with any
terminate-and-stay resident programs that may load
into memory.

2 At the DOS prompt, type dm and press 

ENTER

.

3 Follow the screen instructions until the Select an

Install Option dialog box appears. Select (E)asy Disk
Installation and press 

ENTER

. This puts a single

partition and a quick format on the drive.

4 Verify that the drive model number appears on the

screen. If you have two drives, both model numbers
must appear. Select the drive you want to install and
press 

ENTER

. Disk Manager partitions and formats the

drive and makes it bootable if it is Drive C.

If the model number is not shown, exit Disk Manager
and turn off the computer. Check all cables and
jumper settings. Try again.

5 Follow the instructions in the post-installation

screens.

If the BIOS cannot accept your drive’s geometry, Disk
Manager installs a software driver, Dynamic Drive
Overlay (DDO), on Drive C that allows the computer
to access your drive’s full capacity. Read the
Important Information—Please Read screen carefully;
it tells you how to boot with a diskette when your
computer requires the Disk Manager software driver
to access your drive.

If your computer requires DDO to access your new
Seagate drive, the Disk Manager banner must appear
when you boot the computer after installing the drive. If
the banner does not appear, the computer will not
recognize the drive. Make sure that Drive A is empty
when you boot. Try again.

Caution.  Partitioning or formatting a
drive erases all of the data on it. Seagate
assumes no liability if you erase your
data. Before you partition or format the
drive, be sure to transfer the free software
files stored on the drive at the factory.

1 Insert a bootable DOS diskette into Drive A and boot

your computer.

2 At the A: prompt, type fdisk and press 

ENTER

.

Note.  If you have two drives installed,
the menu displays five options. Option
five allows you to select the drive you
want to partition. Make sure you select
the correct drive.

3 Type 1 for “Create DOS partition or logical DOS drive”

and press 

ENTER

.

4 Type 1 and press 

ENTER

 to “Create primary DOS

partition.” Type yes and press 

ENTER

. This puts the

entire drive on one partition and makes the partition
active. When the partitioning is complete, FDISK
reboots your computer.

At the A: prompt, type format 

d: /s, where d is the letter

of your new hard drive (DOS automatically assigns a
letter for each partition you create).

Caution.  Make sure that you use the
correct drive letter. All data on the drive is
erased during the format.

When the formatting completes, your drive is ready.

You can mount the drive in any orientation. Secure the
drive with four 6-32 UNC-2A mounting screws not more
than six full turns into the drive frame in either the side
mounting holes or the bottom mounting holes. Do not
overtighten. Do not use metric screws. After mounting
the drive, replace the computer cover.

If you are mounting the drive in a 5.25-inch drive bay,
you need a mounting adapter or frame kit. Contact your
computer dealer. Some computers may also require drive
mounting rails, which can be obtained from your
distributor or computer manufacturer.

1 Attach one end of the 40-pin drive interface cable to

the interface connector on your computer or host
adapter as shown below. After threading the cable
through the drive bay, attach your drive or drives to
one of the connectors on the interface cable.

Caution.  Make sure to align pin 1 of the
computer’s interface connector or the
host adapter with pin 1 of your drive or
drives.

The full capacity of your drive exceeds the maximum
capacity many older computers can address. If your
computer’s BIOS was manufactured before June of 1994,
it may not be able to access more than 528 Mbytes.
Several options are available for surpassing the 528-
Mbyte barrier. We recommend the following:

1 Use a hard drive controller or a BIOS upgrade that

supports drives with capacities greater than 528
Mbytes,

or

2 Use the free Disk Manager software stored on your

Seagate drive to install the drive.

Caution.  You must transfer the
replacement 32-bit disk access driver for
Windows 3.1, the free Disk Manager
software and the other software stored on
the drive to a diskette in Drive A before
you partition and format the drive.
Instructions for transferring the software
are provided in Section 2, “Transferring
the Free Seagate Software.”
