Serial ATA interface disc drives are designed for easy installation. It is not  
necessary to set any jumpers, terminators, or other settings on this drive  
for proper operation.  
With a Serial ATA (SATA) interface, each disc drive has its own cable that  
connects directly to a Serial ATA host adapter or a Serial ATA port on your  
motherboard. Unlike Parallel ATA, there is no master-slave relationship  
between drives that use a Serial ATA interface.  
Breather Hole  
Do not cover  
or seal.  
You can use a Serial ATA drive in the same system with Parallel ATA drives  
as long as both interfaces are supported on the motherboard or with a host  
adapter. This makes it easy to add Serial ATA capability to your existing  
system without removing existing Parallel ATA disc drives.  
Caution. Do not cover, seal, or insert any object into this hole. If this hole  
is covered, sealed, or penetrated by any object, the drive reliabil-  
ity may be compromised and could lead to permanent damage  
and voids the warranty.  
Note. This drive ships from the factory with a jumper installed to operate  
at 1.5 Gbits/second as shown in the illustration below. This is for  
maximum compatibility with the widest variety of systems. If your  
system supports 3.0 Gbits/second operation, you may remove this  
jumper.  
Attaching cables and mounting the drive  
1. Attach one end of the drive interface cable to the SATA interface con-  
nector on your computer’s motherboard or SATA host adapter (see  
your computer manual for connector locations).

Each drive requires its own cable.

Refer to your computer system documentation to see if your system sup-  
ports SATA on the motherboard and locate the SATA connector. If your  
system does not have a SATA connector on the motherboard, you must  
purchase a SATA host adapter that is compatible with your computer and  
operating system and install it with the appropriate device driver according  
to the host adapter manufacturer’s installation instructions.  
Note: The drive is inverted in this  
illustration to show the connectors.  
Note. Serial ATA connectors are keyed to ensure correct orientation.  
2. Attach the interface and power cables to the drive.  
3. 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.

Note. Do not overtighten the screws or use metric screws. This may dam-  
Handling precautions/electrostatic discharge protection  
age the drive.  
• Disc drives are fragile. Do not drop or jar the drive. Handle the drive only  
by the edges or frame.  
Configuring the BIOS  
• Drive electronics are extremely sensitive to static electricity. While  
installing the drive, wear a wrist strap and cable connected to ground.  
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.  
• Turn off the power to the host system during installation.  
• Do not disassemble the drive. Doing so voids the warranty. See the  
Warranty information on page 2.  
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. See your system documentation for details  
about your particular system.  
• Do not apply pressure or attach labels to the circuit board or to the top of  
the drive.  
The easiest way to install your drive in a Windows system  
2. Within the system setup program, instruct the system to auto detect  
your new drive.  
To successfully install and obtain the maximum capacity from the drive,  
use DiscWizard for Windows disc drive installation software utility. This util-  
ity is available exclusively from Seagate. You can download this free disc  
or run the program directly from your web browser.  
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 sec-  
tion on the back of this sheet.
