Barracuda 7200 Hard Drives:

Serial ATA interface disk drives are designed for easy installation. It is not necessary to set any jumpers, terminators, or other settings on this drive for proper operation. The jumper block adjacent to the SATA interface connector on SATA 150MB/s drives is for factory use only. The jumper block adjacent to the SATA interface connector on SATA 300MB/s drives can be used to force the drive into SATA 150MB/s mode for use with older SATA controllers that only work with SATA 150MB/s drives.

With a Serial ATA interface, each disk 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.

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 compatibility to your existing system without removing existing Parallel ATA disk drives.

Installation in a Windows System
Note: For a slideshow of the Serial ATA installation process, please visit our Serial ATA Installation Basics page.
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 motherboard that has 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 supports Serial ATA on the motherboard and to locate the Serial ATA connector. If your system does not have a Serial ATA connector on the motherboard, you must purchase a Serial ATA 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: See our list of companies that sell Serial ATA components including host adapters, cables, and power adapters.
Handling Precautions

* Disk 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 anti-static container 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.
* Do not apply pressure or attach labels to the circuit board or to the top of the drive.

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.
