The easiest way to install your drive
DiscWizard is Seagate’s exclusive Windows program that is
included with your drive for easy drive installation.
DiscWizard helps you configure your new drive and your com-
puter. It analyzes your system, lets you select various installation
options and creates customized step-by-step instructions. It also
allows older computers to access the full capacity of large hard
drives. Run this software
before installing your drive.
You can run DiscWizard to install your new hard drive if:
•You already have an existing, bootable hard drive in your com-
puter with at least 3 Mbytes of available disc space,
and
•You are running Windows 95 or Windows 98.
To run DiscWizard:
•Select Run from the Windows Start menu and type
x :\setup,
where
x is the drive letter of your diskette or CD-ROM.
If you cannot run DiscWizard, follow the instructions in this
installation guide to install and configure your new drive.

What you need
•Straight-edge and Phillips screwdrivers
•Four 6-32 UNC drive mounting screws
•A standard 40-pin ATA interface cable,
or an 80-conductor
cable to run Ultra ATA 66 (max length: 18 inches)
•An unused drive power cable for your new drive
Ultra ATA/66 Requirements
The drive can support transfer rates up to 66 Mbytes per second
in Ultra ATA/66 mode. For your drive to run in this mode you
need the following:
•A computer that supports UDMA modes 3 and 4
•A 40-pin 80-conductor cable (maximum length 18 inches)
•A software utility to activate Ultra ATA/66. Seagate provides a
utility called UTA66.exe that is included on your CD, or you can
download it from our Web site at www.Seagate.com.
•The Windows 98 operating system
Before you begin
•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.

Barracuda ATA Family Installation Guide, Rev. A 3
Handling precautions
Disc drives are extremely fragile. Do not drop or jar
your drive.
Keep the drive in its antistatic bag until you are
ready to install it.
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 cir-
cuit board.
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.

Master/slave jumpers
If you already have one hard drive in your computer and you are
installing a second drive, you must configure one drive as a mas-
ter and the other as a slave.
Note. If you need to change the jumpers on your existing hard
drive, see the Disk Manager online manual, look on the
drive label, or contact the drive manufacturer.
Installing a master or one drive only:
•The drive is shipped configured for a master or single-drive
installation with a jumper set on pins 7 and 8.
Note. The master drive usually defaults to being the “boot” drive
(drive C), from which the computer loads system soft-
ware when it first starts up.
Installing a slave drive:
•If you are installing your drive as the second drive on the
cable, remove all the jumpers.

Attaching cables and mounting the drive
1. Attach one end of the drive interface cable to the interface
connector on your motherboard (See your computer manual
for connector locations).
Caution. Align pin 1 on the motherboard connector with
pin 1 on your drive connector. Pin 1 on is marked by a
stripe on one side of the cable.
Figure 2. Attaching the cables
Note. A 40-pin 80-conductor cable is required to run in Ultra
ATA/66 mode. Attach the
blue connector to the mother-
board, the
black connector to the master or single drive,
and the
grey connector to the slave.
2. Attach the interface cable and the power connector to the
new drive.

Note. You can mount the drive in any orientation. Usually it is
mounted with the circuit board down.
Caution. Do not overtighten the screws or use metric
screws. This may damage the drive.
Figure 3. Mounting the drive
3. Secure the drive in the computer using four 6-32 UNC
mounting screws in either the side-mounting or bottom-
mounting holes. Insert the screws no more than 0.22 inch
(5.58 mm) into the bottom-mounting holes and no more than
0.20 inch (5.0 mm) into the side-mounting holes.

Configuring your computer
Before you format or partition your new drive, you must configure
your computer’s BIOS.
To configure your computer’s BIOS:
1. Turn your computer on. As your computer starts up, watch for
a message that describes how to run the system setup pro-
gram (also called BIOS or CMOS setup). This is usually done
by pressing a special key, such as DELETE, ESC OR F1, during
startup. See your computer manual for details. Press the
appropriate key to run the system setup program.
2. Select the BIOS hard drive settings menu. To set the drive
parameters, choose Primary Master or Slave,
or Secondary
Master or Slave.
3. Select automatic drive detection if available. Choosing this
option automatically configures the computer for your new
drive. If your BIOS does not provide automatic drive detec-
tion, select “user-defined” drive settings and enter the CHS
values from the table on page 9. These CHS values support
drive capacities up to 8.4 Gbytes.
4. Verify that LBA mode is enabled. Many BIOS use the logical
block addressing (LBA) mode to access drives with capaci-
ties greater than 528 Mbytes. Most BIOS automatically set
this mode during the auto-detection process.
5. Enable UDMA mode if it is available.
Save the settings and exit the System Setup program. Your com-
puter will automatically reboot.

Barracuda ATA Family Installation Guide, Rev. A 9
Note. Set the
write precomp or landing zone parameters
to zero.
We recommend you use Disk Manager to evaluate your BIOS
and determine whether your system needs additional BIOS sup-
port. For more information, see “Installation using Disk Manager”
on page 12.

Addressing drive-capacity limitations
Some DOS-based computers and operating systems are not
designed to accommodate large-capacity hard disc drives. The
most common system limitations are listed below.
528-Mbyte limit
The BIOS in some older computers cannot support 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.
8.4-Gbyte limit
If your drive’s capacity is greater than 8.4 Gbytes, the capacity
may exceed the limits of your system BIOS and operating sys-
tem. DOS and Windows operating systems and most system
BIOS limit the drive partitions to 8.4 Gbytes per physical drive.
Because of this limitation, a 32-bit file allocation table (FAT32) is
needed to support drive capacities greater than 8.4 Gbytes.
To achieve your drive’s full capacity, you need a Windows operat-
ing system that supports FAT32
and device support for drive
capacities greater than 8.4 Gbytes, from one of the following:
•Third-party device driver, such as Disk Manager (Disk Man-
ager is provided on the DiscWizard diskette or CD included
with your drive), or
•An intelligent ATA host adapter,
or
•A system BIOS upgrade

Preparing your drive for use
Installing a single drive
For a quick installation, we recommend you use Disk Manager to
automatically partition and format your drive.
Disk Manager also ensures that your computer can access the
full capacity of your hard drive. See “Installation using Disk Man-
ager” below.
If you
do not want to use Disk Manager, you can use the stan-
dard DOS commands to partition and format your drive. See
“Standard DOS installation” on page 14.
Installing a second, or slave drive:
Use the DiscWizard software provided with your drive to install
an additional drive. For information on running DiscWizard, see
page 1.
To add a second, or slave drive, without using DiscWizard:
Use the standard DOS commands FDISK and FORMAT. See
“Standard DOS installation” on page 14.
Installation using Disk Manager
Note. The Disk Manager software is stored on the diskette or
CD provided with your drive.
1. Boot your computer from your Windows startup diskette.
Insert your DiscWizard diskette or CD (If you are using the
CD, change to the drive letter of your CD-ROM).
2. At the prompt, type dm. Then press ENTER.
3. Follow the onscreen instructions until you see the
Select an
Installation Option
menu.

Barracuda ATA Family Installation Guide, Rev. A 13
4. Select either
(E)asy Disk Installation or (A)dvanced Disk
Installation.
Disk Manager lists all the hard drives that it detects. 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.
5. If Disk Manager recognizes all your drives, select the drive
you want to install and press ENTER. Disk Manager partitions
and formats the drive.
Important. If your BIOS does not support drive capacities
greater than 8.4 Gbytes, Disk Manager installs a
Dynamic Drive Overlay (DDO) on your hard drive. If
this driver has been installed, you should see a blue
Disk Manager banner each time you boot your com-
puter. See the Disk Manager online manual for
details.
6. Follow the instructions in the post-installation screens.

14 Barracuda ATA Family Installation Guide, Rev. A
Standard DOS installation
Caution. Partitioning or formatting a drive erases all data
on it. Seagate assumes no liability if you erase your data.
Drive partitioning
Partitioning a hard drive divides it into sections (partitions) that
function as separate logical drives (labeled C,D,E, etc.).
To partition your new drive using DOS:
1. Insert a bootable DOS diskette into your diskette drive and
restart your computer. (Seagate recommends using DOS
Version 5.0 or greater.)
2. Insert a DOS program diskette that has 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 dis-
plays five options. Option five allows you to select the drive
you want to partition. Make sure that your new drive is
selected.
4. Select “Create DOS partition or logical DOS drive” by press-
ing 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 computer
(drive C), make sure 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.
!

Barracuda ATA Family Installation Guide, Rev. A 15
7. When partitioning is complete, FDISK reboots your com-
puter. Proceed to “Drive Formatting.”
Note. If you are adding a second drive to your system, you can
run FDISK from Windows. Click the
á
Start button.
Select Run... Then type fdisk and click OK.
Drive formatting
Caution. Use the correct drive letters so that you
do not
format a drive that already contains data.
At the A: prompt, type format
x :/s, where
x is the letter of your
first new partition. Repeat the format process for all the new par-
titions you have created.
Note. From FDISK in Windows, it is not necessary to add the /s
to the format command because these system files are
automatically added.
Loading the Operating System
1. Boot your computer from your Windows startup diskette with
the Windows CD loaded.
At the prompt, type
x:\ setup, where
x is the drive letter of your
CD-ROM drive. Continue with the Windows setup instructions.

Additional installation options
Figure 4. Non-ATA compatible and cable select jumpers
Non-ATA compatible slave jumper
If your computer does not recognize your new drive as a master
in a two-drive system, the slave drive may not be ATA-compati-
ble. You may be able to solve this problem by setting a jumper on
pins 5 and 6 and a jumper on pins 7 and 8 as shown in Figure 4.
Cable-select jumper
Some computers differentiate between master and slave drives
using specially designed interface cables, where the line to pin
28 (the cable select pin), is removed or cut at one connector. The
connector that has pin 28 disabled is used for the slave drive.
See your computer manual to determine whether your computer
supports this feature. To configure your drive for cable select, set
a jumper on pins 5 and 6 as shown above.
