Application. Your drive is designed for IBM AT and compatible
personal computers, particularly laptop and notebook models.
Warning. Turn off the computer (and, if you have a notebook or
laptop computer, remove the battery) before you open
the case or touch any internal components.
Caution. Special training or tools may be needed to service
laptop and notebook computers. Opening the case
may void your warranty. Review the terms and conditions of your warranty before opening the case.
Static discharge. Observe the following precautions:
• Before handling any components, put on a grounded wrist strap.
• Use antistatic padding on all work surfaces.
• Avoid static-inducing carpeted areas.
• Keep the drive in its static-shielded bag until you are ready to
complete the installation. Do not attach any cables to the drive
while it is in its static-shielded bag.
• Handle the drive by its edges or frame.
• Do not touch the I/O connector pins or the circuit board.
Drive handling. The drive is extremely fragile—handle it with
care. Do not attach labels to any part of the drive.
Inspection. After you are familiar with the handling precautions
listed above, inspect the drive. If it appears to be damaged, call
your distributor or dealer immediately.
Warranty. See your authorized Seagate
Maintenance and repair. Seagate drives do not require main-
tenance. The head/disc assembly is sealed; if you break the seal,

you void the warranty. Seagate customer service centers are the
only facilities authorized to repair Seagate drives. Seagate does
not sanction any third-party repair facilities.
Configuring the drive
1. Put on a grounded wrist strap. Wear the grounded wrist
strap throughout the installation procedure.
2. Install master/slave jumpers. In a two-drive system, you
need to designate one drive as the master, or drive 0, and
the other drive as the slave, or drive 1. To do this, install the
master/slave jumpers as shown in Figure 1. In a one-drive
system, configure the drive as a master (no jumpers installed).
Alternatively, you can configure the drive as a master or
slave using the cable select option. This requires a special
daisy-chain cable that grounds pin 28 (CSEL) on one of its
two drive connectors. If you attach the drive to the grounded
CSEL connector, it becomes a master. If you attach the
drive to the ungrounded CSEL connector, it becomes a
slave. To use this option, the host system and both drives
must support cable select.
To configure an ST9300 family drive for cable select, install
both master/slave jumpers.
Attaching cables
This drive is designed for a host computer that supplies
interface signals and +5V power through a single 44-pin
connector and cable. If your computer has a fixed connector
that attaches directly to the drive, skip ahead to the following

section, “Mounting the drive.” Otherwise, perform the following
steps:
1. Turn off the computer and remove the battery.
2. Put on a grounded wrist strap.
3. Open the case of your computer. See your system manual
for instructions.
Caution. Opening the case may void your computer’s warranty.
4. Connect the 44-pin interface/power cable. Match pin 1 of
the cable to pin 1 of the interface connectors on the drive and
on the computer. Pin 1 is usually denoted by a stripe along
one edge of the cable. The location of pin 1 on the drive
interface connector is shown in Figure 1 on page 3. The cable
should be no longer than 18 inches (0.457 meters).
Caution. The printed circuit cables used in some laptop com-
puters are delicate. Be careful not to tear them.
Mounting the drive
Mount the drive securely in the computer using M3X0.5 metric
screws in the four bottom mounting holes or the four side
mounting holes. You can mount the drive in any orientation. Be
careful not to strain or crimp the interface/power cable.
Caution. To prevent damage to the drive:
• Be careful not to bend the drive connector pins, especially
when plugging the drive into a fixed connector.
• Use mounting screws of the correct size and length.
• Gently tighten the mounting screws—do not apply more than
3 inch-pounds of torque.
• Do not insert mounting screws more than 0.15 inch.

Note. This drive meets industry-standard MCC mounting speci-
fications. When installing this drive in a fixed-mounting
application, you must use MCC-compatible connectors
and mounting hardware. If the mounting holes in your
computer do not line up with the mounting holes on the
drive, your computer may not be MCC-compatible.
Configuring your computer
Before your computer can recognize a new drive, you must enter
basic information about the drive into the computer’s long-term
memory (usually a battery-powered CMOS chip). The computer’s basic input/output system (BIOS) uses this information to
control the flow of data to and from the drive.
Note. Some newer computers can automatically determine your
drive type and configure themselves appropriately at startup.
Read your system manual to determine whether this applies
to your computer. If so, then skip ahead to the following
section, “Formatting and partitioning the drive,” on page 7.
In most computers, you must enter the number of cylinders,
heads and sectors using the system setup program (see page
6). The table below lists data for the ST9300 family drives.

To configure your system BIOS, follow these steps:
1. Turn on your computer.
2. Run the system setup program. This program configures
the system BIOS to recognize your drive. In some computers
you run the system setup program by pressing special keys
while the computer is booting up. In other computers, you can
run the program from the DOS prompt. See your system
documentation for more information.
3. Enter your drive specifications. Within the system setup
program, there are three possible ways that you can enter
your drive’s specifications. These are listed below in order of
increasing complexity.
• Select a predefined drive type. Most system setup pro-
grams provide a long list of predefined drive types. Select a
drive type with specifications that match those of your drive
(refer to the table on page 5).
• Specify a
system setup program doesn’t list a predefined drive type
that matches your drive specifications, you may be able to
define a custom or user-defined drive type. You can then
enter your drive specifications (from the table on page 5).
When you enter drive specifications for a custom or userdefined drive type, the setup program should display a
drive capacity less than or equal to the
capacity
than the usable drive capacity.
• Allow your drive to emulate or
predefined drive types. If none of the predefined drive
types exactly matches your drive, and your system setup
program does not allow you to specify a custom drive type,
custom
or
user-defined
drive type. If the
