The easiest way to install your drive
Many of today’s computers have been designed to make it possible for the
end user to replace the hard drive. Refer to your system’s user manual for
the location of the hard drive compartment and the specific instructions
regarding replacement.
Some systems are sealed and require specialized tools to gain access to
the hard drive.
Caution. Special training or tools may be needed to service some com-
puters. In some cases, opening the case may void your war-
ranty. Consult your system documentation.
Seagate recommends taking your system to an authorized service techni-
cian to replace your hard drive.
Refer to your system manufacturer’s support website for the most up-to-
date information. Read and follow all instructions regarding the proper
steps to be taken when replacing the systems hard drive.
What you need
• A Phillips screwdriver
• Existing drive mounting screws (reuse)
• Existing drive mounting framework, cage or tray (reuse)
• SATA interface either on the motherboard or as an add-on host adapter
Handling precautions/electrostatic discharge protection
• 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 electrostatic discharge
(ESD) bag 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. See the war-
ranty information on page 2.
• Do not apply pressure or attach labels to the circuit board or to the top of
the drive.

Replacing the existing hard drive
Each system has its own unique hard drive compartment. Refer to your
system manual to locate the hard drive compartment and for instructions
on removing and replacing the hard drive.
Warning. Turn off the computer. If you are installing the drive in a note-
book or laptop computer, disconnect the power charger/adapter
and remove the battery before you open the case or touch any
internal components.
Note. This drive is designed for a host computer that supplies interface
signals and +5V power through a single SATA connector. Most
mobile computers have a fixed connector that attaches directly to
the drive.
Serial ATA drives are designed for easy installation with no jumpers, termi-
nators, or other settings. It is not necessary to set any jumpers on this drive
for proper operation. The jumper block adjacent to the signal connector is
for factory use only.
Drive mounting
You can mount the drive using four screws in the side-mounting holes or
four screws in the bottom-mounting holes. See Figure 1 for drive mounting
dimensions. Follow these important mounting precautions when mounting
the drive:
• Allow a minimum clearance of 0.030 inches (0.76 mm) around the entire
perimeter of the drive for cooling.
• Use only M3 x 0.5 mounting screws.
• Gently tighten the mounting screws (maximum torque: 4.0 in-lb).
• Four (4) threads (0.080 inches) minimum screw engagement recom-
mended.

Configuring the BIOS
After completing the drive installation, restart your computer. Your com-
puter may automatically detect your new drive. If your computer does not
automatically detect your new drive, follow the steps below.
1.
Restart your computer. While the computer restarts, run the system
setup program (sometimes called BIOS or CMOS setup). This is usu-
ally done by pressing a special key, such as DELETE, ESC, or F1 dur-
ing the startup process.
2.
Within the system setup program, instruct the system to auto detect
your new drive.
3.
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 this sheet.
System manufacturer’s operating system restore CD
Refer to your system documentation for specific instructions on restoring
the operating system on your newly installed hard drive. Many computers
require the use of an operating system restore CD, originally shipped with
the system, to reload the operating system on the hard drive.
