Installing a Western Digital SATA drive takes just a few simple steps.

1. Open your computer

2. Set the jumpers (see chart).

3. Attach the power supply cable.

4. Attach the SATA interface cable.

5. Mount the drive in a 3.5" device bay. Use either the four bottom screws or four of the side mounting screws to support the drive.

6. Close the computer and turn it on.

7. Use the Data Lifeguard Utilities, included in your kit or downloadable here, to complete the installation and transfer your data from one drive to another.

This information provides the basic steps of drive installation. For more detailed information please refer to the technical documentation shown on the right.

Don't forget to register!
Now it's easy to register your drive with WD. Just write down the serial number on your drive, or use the Data Lifeguard CD to find the serial number once it has been installed.
