The easiest way to install your drive
DiscWizardTM, available exclusively from Seagate, provides you with cus-
tomized installation instructions for your hard drive. You can download Dis-
or run the program directly from your web browser. In either case, you
should run DiscWizard before you install your drive.
2. Mount the drive and attach cables
a. Slide the drive into a 3.5-inch drive bay. You can mount the drive in any
orientation, but we recommend mounting with the circuit board down.
Note. To mount the drive in a 5.25-inch drive bay, you must purchase
mounting brackets, available from your computer dealer.
b. Secure the drive using four 6-32 UNC mounting screws in either the
side-mounting or bottom-mounting holes. Insert the screws no more
than 0.20 inches (5.08 mm) into the bottom-mounting holes and no
more than 0.14 inches (3.55 mm) into the side-mounting holes.
If you cannot run DiscWizard, follow the instructions on this installation
sheet to install and configure your drive.
What you need
Caution. Do not overtighten the
• A Phillips screwdriver and four 6-32 UNC drive mounting screws
• Forced-air ventilation to provide adequate drive cooling
screws or use metric
screws. This may dam-
age the drive.

• An ATA interface cable. For optimum drive performance and data integ-
rity, we recommend using an 80-conductor Ultra ATA/100 cable (which
can be identified by its blue, gray, and black connectors).
c. Make sure the blue connector
on your Ultra ATA/100 cable is
plugged into the primary IDE
port on your computer’s moth-
erboard or host adapter. See
your computer manual to deter-
mine the location of the primary
IDE connector.

Handling precautions/Electrostatic discharge protection
Motherboard
• Disc drives are fragile. Do not drop or jar the drive. Handle the drive only
by the edges or frame. Keep the drive in the protective SeaShellTM con-
tainer until you are ready to install it to minimize handling damage.
• Drive electronics are extremely sensitive to static electricity. While
installing the drive, wear a wrist strap and cable connected to ground.
• Turn off the power to the host system during installation.
• Do not disassemble the drive; doing so voids the warranty. Return the
entire drive for depot service if any part is defective.

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

Caution. When plugging in the

sure that pin 1 on the cable (indicated by a stripe along the
edge) is attached to pin 1 on the drives and on the mother-
board’s IDE connector.
f. Attach the 4-pin power connector to the drive. See figure below.

Caution. Do not cover, seal, or insert any object into this hole.
This hole has two purposes:
Note. If your computer does not have an unused power cable for your new
hard drive, you can purchase a Y-shaped power splitting cable from
your computer dealer which effectively converts one power connec-
tor into two.
• To allow condensation inside the hard disc to escape
• To allow air pressure inside the hard disc to equalize with ambient pres-
sure
Note. If this hole is covered, sealed, or penetrated by any object, the drive
reliability may be compromised and could lead to permanent
damage—doing so voids the warranty.
3. Start up your computer
Close your computer case and restart your computer. your computer may
automatically detect your new drive. If your computer does not automati-
cally detect your new drive, follow the steps below.
Installation instructions
a. Restart your computer.
1. Set the jumpers
b. While the computer restarts, run the System Setup program (some-
times called BIOS or CMOS setup). This is usually done by pressing a
special key, such as DELETE, ESC, or F1 during the startup process.
c. Within the System Setup program, instruct the system to auto detect
your new drive.
Note. The instructions below assume that you are installing your new
Seagate drive in a system that already has a working hard drive. To
install the drive in a system that has no working hard drive, see the
section titled, “What to do if you don’t have a working hard drive”
located on back of this sheet.
d. Enable LBA and UDMA modes if the Setup program gives you this
option.
a. Make sure that your existing drive is set up as a “master.” See the drive
label or manufacturer’s web site for jumper settings.
e. Save the settings and exit the Setup program. When your computer
restarts, it should recognize your new drive. If your system still doesn’t
recognize your new drive, see the troubleshooting section on the back
b. Your new drive is shipped with a jumper in the “cable select” position.
Set the drive as a “slave” by removing this jumper from the jumper
pins. Save the jumper in case you ever need to reconfigure the drive.
