The easiest way to install your drive

Many of today’s mobile computers have been designed to make it possible for the end user to replace the hard drive. Refer to your system’s user man- ual for the location of the hard drive compartment and the specific instruc- tions regarding replacement.

Some mobile 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 mobile computers. 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)

•ATA interface adapter (built into notebook and laptop systems)

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 have a notebook or laptop com- puter, disconnect the power charger/adapter and remove the battery before you open the case or touch any internal compo- nents.

Note. This drive is designed for a host computer that supplies interface signals and +5V power through a single 44-pin connector. Most mobile computers have a fixed connector that attaches directly to the drive.

Setting the jumpers

Refer to the jumper settings in Figure 1 or on your drive label to configure the drive for your system. Jumper settings can also be accessed online from our web site at www.seagate.com.

Master or single drive: Use the options jumper block shown in Figure 1 to configure the drive for operation. This jumper block is the 4-pin header adjacent to pins 1 and 2 of the I/O signal pins.

Note. For mobile system operation, use cable select (default) or master.

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 2 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 UNC mounting screws. (Reusing the existing screws may be acceptable provided the maximum screw penetration depth of 0.098 inches is not exceeded.)

•Gently tighten the mounting screws (maximum torque: 4.0 in-lb).

•Four (4) threads (0.080 inches) minimum screw engagement recom-

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.
