Disc drives are extremely fragile. Do not drop or jar
your drive.

DiscWizard



 is a revolutionary new Windows program that

makes it easy to install your new Seagate drive. DiscWizard
helps you configure your new drive and your computer. It ana-
lyzes your system, lets you select various installation options
and creates customized step-by-step instructions. It also al-
lows older computers to access the full capacity of your drive.

• You already have an existing, bootable hard drive in your

computer with at least 3 Mbytes of available disc space 

and

• You are running Windows 3.

x or Windows 95.

If you can run DiscWizard, you do not have to read this instal-
lation guide. Instead, 

before you install your new drive, follow

the instructions on the DiscWizard diskette to install your
drive. DiscWizard provides all the information you need to
install your new drive.

If you cannot run DiscWizard, follow the instructions in
this installation guide to install and configure your new
drive. For additional information and troubleshooting

tips, see the back of this sheet. This symbol: 

 indi-

cates that additional information on a topic appears on

the back of this sheet.

• Straight-edge and Phillips screwdrivers

• Drive mounting screws

• An ATA host adapter and interface cable (max. length:

18 inches) with enough connectors for all your drives

• An unused drive power cable for your new drive

• A bootable DOS system diskette (Seagate recommends

using DOS Version 5.0 or later.)

• If you are mounting this 3.5-inch drive in a 5.25-inch

drive bay, you need a mounting adapter or frame kit.
Also, you may need drive mounting rails if your drive
bay is not designed for direct mounting.

• Make sure your computer is turned off before you open

the case.

• Read the handling precautions at the right and inspect the

drive to make sure that it is not damaged.

• Save your foam-lined Seagate disc drive box. This box

has been approved by Seagate for shipping a Seagate
disc drive. Using any other container or packing
material voids your drive warranty.

Keep the drive in its antistatic bag until you are ready
to install it.

Always handle the drive by its edges or frame.

Do not apply pressure or attach labels to the circuit
board or the top of the drive.

Caution.  Partitioning or formatting a drive
erases all data on it. Seagate assumes no
liability if you erase your data.

Partitioning a hard drive divides it into sections (partitions)
that function  as separate logical drives (labeled C, D, E, etc.).
Because DOS computers cannot access partitions larger than
2.1 Gbytes, you must divide large-capacity hard drives into
multiple partitions. In creating partitions, keep in mind that the
larger the partition, the more drive space is taken up in un-
used clusters. For this reason, if most of your files are
smaller than 50 Kbytes, you should use partitions of 1 Gbyte
or less. To partition your new drive:

1 Insert a bootable DOS diskette in your diskette drive and

restart your computer.

2 Insert a DOS program diskette that contains the FDISK.EXE

and FORMAT.COM programs into your diskette drive. At the
A: prompt, type FDISK and press 

ENTER

.

3 If you have two hard drives installed, the FDISK menu

displays five options. Option five allows you to select the
drive you want to partition. Make sure that your new drive
is selected.

1 Boot your computer from a bootable DOS diskette (use MS

DOS Version 5.0 or later). Booting from a diskette ensures
that the Disk Manager installation does not conflict with
any terminate-and-stay-resident (TSR) programs.

2 Insert your DiscWizard diskette. The Disk Manager soft-

ware is stored on this diskette.

3 At the DOS prompt, type DM and press 

ENTER

.

4 Follow the onscreen instructions until you see the 

Select

an Installation Option menu.

5 Select either 

(E)asy Disk Installation or (A)dvanced Disk

Installation.

Because DOS computers cannot access partitions larger
than 2.1 Gbytes, Disk Manager may have to divide your
hard drive into multiple partitions. If you select 

(E)asy Disk

Installation, Disk Manager creates one partition of 2.1
Gbytes and creates multiple partitions using the remainder
of your hard disc. However, if most of your files are
smaller than 50 Kbytes, you may want to create several
smaller partitions to make more efficient use of your hard
disc space. To create smaller partitions, select  

(A)dvanced

Disk  Installation  from the Disk Manager main menu.

Protect your drive from static discharge by making sure you
are well-grounded before touching the drive. We recommend
wearing a grounded wrist strap throughout the installation
process. Do not touch the connectors or any part of the
printed circuit board.

1 If you are installing a new ATA interface cable, attach one

end of the cable to the interface connector on your com-
puter or host adapter. The ATA cable must be no more than
18 inches long.

2 Thread the interface cable through the drive bay and attach

the connector at the end of the interface cable to your new
drive. If you have two drives, attach the second drive to
the second connector.

Caution.  Make sure to align pin 1 on the com-
puter or host adapter interface connector with
pin 1 on your drive or drives. Pin 1 on the
interface cable is usually indicated by a stripe
along the edge of the cable.

6 At this point, Disk Manager lists all the hard drives that it

can recognize. You should see your new Seagate drive and
your existing hard drive, if any.

If any hard drive is not recognized, exit Disk Manager and
turn off your computer. Check all cables, jumpers and BIOS
settings. Then start at step 1 to run Disk Manager again.

7 If Disk Manager recognizes all your drives, select the drive

you want to install and press 

ENTER

. Disk Manager parti-

tions and formats the drive. If your new drive is the master
drive (Drive C), Disk Manager also configures the drive so
that you can boot from it.

Note. If your computer cannot accommodate
hard drives with capacities greater than 528
Mbytes, Disk Manager installs a 

Dynamic

Drive Overlay (DDO) on your hard disc. If this
driver has been installed, you should see a
blue Disk Manager banner each time you boot
your computer. See the Disk Manager online
manual for details.

8 Follow the instructions in the post-installation screens.

4 Select “Create DOS partition or logical DOS drive” by

pressing 1. Then press 

ENTER

.

5 Select “Create primary DOS partition” by pressing 1 again.

Then press 

ENTER

. Create your first drive partition. If you

are creating a partition that will be used to boot your com-
puter (drive C), make sure that the partition is marked
active.

6 Create an extended partition and additional logical drives,

as necessary, until all the space on your new hard drive
has been partitioned.

7 When the partitioning is complete, reboot  your computer.

At the A: prompt, type format 

x: /s, where x is the letter of

your first new partition. Repeat this process for all the new
partitions you have created.

Caution.  Make sure to use the correct drive
letters so that you do not format a drive that
already contains data.

After you format your drive, it is ready to use.

3 Slide the drive carefully into the drive bay. Secure the drive

with four 6-32 UNC-2A mounting screws in either the side-
mounting holes or the bottom-mounting holes. Do not over-
tighten the screws. The screws should be inserted no more
than  0.22 inch into the bottom mounting holes and no more
than 0.14 inch into the side mounting holes. Do not use
metric screws.

Note. 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

Partition-size limit: DOS/Windows and Windows 95 can-
not access drive partitions larger than 2.147 Gbytes. You
can overcome this limitation using the Disk Manager
software or the DOS FDISK command to divide your
drive into several smaller partitions. Each partition acts
as a separate logical drive, with its own drive letter. If
most of your files are smaller than 50 Kbytes, you should
divide your drive into partitions of 1 Gbyte or less to
make the most efficient use of your disc space.

BIOS Upgrades: If you need to upgrade your BIOS, contact the
appropriate BIOS manufacturer listed below.

these parameters to zero.

4 Save the settings and exit the System Setup program

(your computer will automatically reboot).

After you configure your computer, we recommend that you
use Disk Manager to partition and format your drive.
If your computer was built before mid-1994, you probably will
not be able to access the full capacity of your new drive un-
less you use Disk Manager. For instructions, see Section 3A,
“Installation Using Disk Manager,” below.

If you do not want to use Disk Manager, you can use the stan-
dard DOS commands to partition and format your drive, as
described in Section 3B.

If your new Seagate

®  

Medalist 

®

Pro drive will be the only drive in

your computer, you do not have to change any jumper settings.
In this case, skip ahead to “Attaching Cables and Mounting the
Drive.”

If you already have one hard drive in your computer and you
are installing a second drive, you must configure one drive as a
master and the other as a slave. The master drive will be the
“boot” drive (drive C), from which the computer loads system
software when it first starts up. To configure your new Seagate
drive as the master, slide a jumper onto pins 7 and 8 (see be-
low). To configure the drive as a slave, slide a jumper onto pins
5 and 6 only. The jumper on pins 6 and 8 is a spare and does
not affect drive operation. If you need to change the jumpers on
your existing hard drive, see the Disk Manager online manual,
or contact the drive manufacturer.

Before you format or partition your new drive, you must con-
figure your computer’s BIOS so that the computer can recog-
nize your new drive.

1 Turn your computer on. As your computer starts up, watch

the screen for a message describing how to run the sys-
tem setup program (sometimes called BIOS or CMOS
setup). This is usually done by pressing a special key, such
as 

DELETE

, 

ESC

, or 

F

1

, during startup. See your computer

manual for details. Press the appropriate key to run the
system setup program.

2 Enable LBA mode if it is available. Many BIOS use the logi-

cal block addressing (LBA) mode to access drives with
capacities greater than 528 Mbytes.

3 If your BIOS provides automatic drive detection (an

“Auto” drive type), select this option. This allows your
computer to configure itself automatically for your new
drive.

If your BIOS does not provide automatic drive detection,
select “User-defined” drive settings. If your computer
supports LBA addressing, enter the LBA cylinder, head
and sector values for your drive from the table at the
top of the next column. If your computer does not sup-
port LBA addressing, enter the CHS values from the table.

Some DOS-based computers and operating systems are not
designed to accommodate large hard disc drives. The three
most common system limitations are listed below, along with
methods for overcoming these limitations. See your system
manual to determine which (if any) of these limitations applies
to your computer.

528-Mbyte limit: The BIOS in some older computers cannot
accommodate drives with capacities greater than 528 Mbytes.
Seagate provides free Disk Manager software with your drive
to overcome this limitation. Alternatively, you can purchase a
hard drive controller or a BIOS upgrade that supports drives
with capacities greater than 528 Mbytes.

The 32-bit disk access feature in Windows 3.1 does not work
with drives that have capacities greater than 528 Mbytes. If
you want to use 32-bit disk access with Windows 3.1, install
the Seagate replacement 32-bit access driver, SEG32BIT.386,
as described on the back of this sheet.

4,096-cylinder limit: The BIOS in some computers cannot
support drives that have more than 4,096 cylinders.

 If you

install a drive that has more than 4,096 cylinders in one of
these computers, the computer may “freeze” or fail to boot. If
this occurs, see “Advanced Troubleshooting” on the back side
of this sheet.

Pin 1

computers also require drive mounting rails,
which can be obtained from your distributor or
computer manufacturer.

4 Attach a power cable to each drive. If your computer does

not have an unused power connector, you can purchase a
Y-shaped power cable from your computer dealer.

5 Check all cable connections and then replace your com-

puter cover. Continue to step 2 below.
