The Easiest Way to Install Your Drive
is Seagate's exclusive Windows program that is included with
your drive for easy drive installation. You can use this software if you have a
bootable hard drive in your computer and are running Windows 95 or 98.
Run DiscWizard before installing your drive for customized step-by-step
instructions for your system.
To run DiscWizard:
Select Run from the Windows Start menu and type x :\setup, where x is
the drive letter of your CD-ROM.
If you cannot run DiscWizard, follow the instructions on this installation
sheet to install and configure your drive.
What You Need
Phillips screwdriver and four 6-32 UNC drive mounting screws
A standard 40-pin ATA interface cable, or an 80-conductor cable to run
Ultra ATA 100 (max length: 18 inches)
An unused drive power cable for your new drive
Windows 98 to support drives greater than 33.8 Gbytes
Ultra ATA/100 Requirements
The drive can support transfer rates up to 100 Mbytes per second
(UDMA 5) in Ultra ATA/100 mode. For your drive to run in this mode, you
need the following:
A computer that supports UDMA mode 5
A 40-pin 80-conductor cable (available from your dealer)
A software utility to confirm and activate Ultra ATA/100. Seagate
a utility called UATA100.exe. You can download the latest version from our
Web site at www.seagate.com.
The Windows 98 operating system
Disc drives are extremely fragile. Do not drop or jar the drive.
Keep the drive in the protective SeaShell
ready to install it. This minimizes handling damage.
The drive has a protective cover called SeaShield
this permanent cover—it protects the drive from electrostatic
discharge (ESD) and minor impact damage.
Protect your drive from static discharge by wearing a grounded wrist
strap throughout the installation process.
Always handle the drive by the edges or frame.
Do not apply pressure or attach labels to the circuit board or the
top of the drive.
Setting the Jumpers
Refer to the jumper settings below to configure the drive for your system.

Limit drive capacity
40 Gbytes = 32 GB
<40 Gbytes = 2.1 Gbytes
Master or single-drive: The drive is shipped configured for a master
or a single drive with a jumper set on pins 7 and 8.
Drive is slave: To configure the drive as a slave, or second drive on
the cable, remove all the jumpers.
Master with non-ATA compatible slave: Use this setting if the slave
drive is not recognized. Configure the master drive with a jumper set on
pins 5 and 6 and pins 7 and 8 to enable this option.
Cable-select option: Computers that use cable-select determine the
master and slave drives by selecting or deselecting pin 28, CSEL, on
the interface bus. To enable cable select, set a jumper on pins 5 and 6.
Alternate capacity jumper: Drives with a 40-Gbyte capacity are limited
to 33.8 Gbytes. Drives with 30 Gbytes or less are limited to 2.1 Gbytes.
Attaching Cables and Mounting the Drive
1. Attach one end of the drive interface cable to the interface connector
on your computer's motherboard (see your computer manual for
Caution. Align pin 1 on the motherboard connector with pin 1 on
your drive connector. Pin 1 is marked by a stripe on one side of the cable.
2. Attach the interface connector and the power connector to the drive.
Note. You can mount the drive in any orientation. Usually it is mounted
with the circuit board down.
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 0.20 inch (5.08 mm) into the bottom-mounting
holes and no more than 0.14 inch (3.55 mm) into the side-mounting holes.
Caution. Do not overtighten the screws or use metric screws. This
may damage the drive.
Configuring the BIOS
For your computer to recognize your new drive, configure your
computer's BIOS as follows:
1. Run the system setup program.
2. Enable LBA mode and UDMA mode, if available.
3. Select the auto-detect option. If this is not available, select "User-
defined drive type" and enter the CHS (cylinder, head, sectors)
parameters for your drive from the table listed below. The CHS
addressing supports capacities up to 8.4 Gbytes only. To access the
full capacity of the drive, use LBA mode.
4. Save and exit the system setup program.
*One sector equals 512 bytes.
Note. If you are using a 40-pin 80-conductor
cable, attach the blue connector to the
motherboard, the black connector to the
master drive, and the grey connector
to the slave.
