Serial ATA (SATA) Interface Disc Drives
Publication Number: 100383102, Rev. A, August 2005
Serial ATA interface disc drives are designed for easy installation. It is nor-
mally not necessary to set any jumpers, terminators, or other settings on
this drive for proper operation.
With a Serial ATA interface, each disc drive has its own cable that connects
directly to a Serial ATA host adapter or a Serial ATA port on your mother-
board. Unlike Parallel ATA, there is no master-slave relationship between
drives that use a Serial ATA interface.
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.
The easiest way to install your drive
To successfully install and obtain the maximum capacity from the drive,
use DiscWizard‰ 2003 disc drive installation software utility. This utility is
available exclusively from Seagate. You can download this free disc drive
installation software from our web site at www.seagate.com/support or run
the program directly from your web browser. In either case, you should run
DiscWizard before you install your drive.
Note. Older versions of DiscWizard do not recognize Serial ATA model
numbers. Make sure that you use DiscWizard 2003 or later when
installing a Barracuda‚ 7200.7 Serial ATA disc drive.
To run DiscWizard:
Follow the instructions on the download page at www.seagate.com to cre-
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.
What you need
• A Phillips screwdriver and four 6-32 UNC drive mounting screws.
• A Serial ATA interface cable (sold separately). Maximum length is 39
inches (1 meter).
• A Serial ATA-compatible power cable or adapter (sold separately).
• A version of Windows with FAT32 or NTFS file system.
• A system with a Serial ATA connector on it, or a Serial ATA host adapter
and available PCI slot in which to install the adapter.
Refer to your computer system documentation to see if your system sup-
ports Serial ATA on the motherboard and to locate the Serial ATA connec-
tor. If your system does not have a Serial ATA connector on the
motherboard, you must purchase a Serial ATA host adapter that is compat-
ible with your computer and operating system and install it with the appro-
priate device driver according to the host adapter manufacturer’s
installation instructions.
Note. See www.seagate.com/support/disc/sata/ for a list of companies
that sell Serial ATA components including host adapters, cables,
and power adapters.
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 protective SeaShell‰ con-
tainer 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
Warranty information on page 2.
• Do not apply pressure or attach labels to the circuit board or to the top of
the drive.
Breather filter hole precaution
Caution. Do not cover, seal, or insert any object into this hole.
Note. If this hole is covered, sealed, or penetrated by any object, the drive
reliability may be compromised and could lead to permanent
damage—doing so voids the warranty.

Attaching cables and mounting the drive
1.
Attach one end of the drive interface cable to the Serial ATA interface
connector on your computer’s motherboard or Serial ATA host adapter
(see your computer manual for connector locations). Host adapter
configuration is shown below.
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-
age the drive.
Breather Hole
Do not cover
or seal.
