Serial ATA (SATA) Interface Disc Drives
Breather Hole

or seal.
Publication Number: 100409438, Rev. A, September 2006
Serial ATA (SATA) interface disc drives are designed for easy installation. It
is normally not necessary to set any jumpers, terminators, or other settings
on this drive for proper operation.
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.
With a SATA interface, each disc drive has its own cable that connects
directly to a SATA host adapter or a SATA port on your motherboard.
Unlike Parallel ATA, there is no master-slave relationship between drives
that use a SATA interface.
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).
You can use a SATA 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 SATA capability to your existing system
without removing existing Parallel ATA disc drives.
Note:
Each drive requires its own cable.
What you need
Attach the SATA interface
cable to the motherboard
or SATA host adapter
• A Phillips screwdriver and four 6-32 UNC drive mounting screws.
• A SATA interface cable (sold separately). Maximum length is 39 inches
(1 meter).
• A SATA-compatible power cable or adapter (sold separately).
• A system with a SATA connector on it, or a SATA host adapter and avail-
able PCI slot in which to install the adapter.
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. Serial ATA connectors are keyed to ensure correct orientation.
Handling precautions/electrostatic discharge protection
2. Attach the interface and power cables to the drive.
• Disc drives are fragile. Do not drop or jar the drive. Handle the drive only
by the edges or frame.
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.
• 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.
Note. Do not overtighten the screws or use metric screws. This may dam-
• Do not disassemble the drive. Doing so voids the warranty. See the
Warranty information on page 2.
age the drive.
Configuring the BIOS
• Do not apply pressure or attach labels to the circuit board or to the top of
the drive.
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.
The easiest way to install your drive in a Windows system
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.
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.
Note. Older versions of DiscWizard do not recognize Serial ATA model
numbers. Make sure that you use DiscWizard for Windows or later
when installing a NL35.2 Series® Serial ATA disc drive.
2. Within the system setup program, instruct the system to auto detect
your new drive.
3. Save the settings and exit the setup program.
To run DiscWizard:
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.
ate a diskette and complete the installation.
If you cannot run DiscWizard, follow the instructions on this installation
sheet to install and configure your drive.
Note. Some systems may see the drive and classify it as a SCSI device.
This is normal even though this is not a SCSI disc drive. This does
not affect performance or capacity.
