How to Add a SATA Hard Drive

With the older EIDE hard drive interface quickly becoming obsolete compared to the newer SATA specification, it is important for computer owners and builders to understand the process of adding a SATA hard drive. SATA hard drives use a smaller interface for data and power connectors while offering hot swapping capabilities. Installing a SATA hard drive is an easy computer hardware process that can be done by any computer user within a matter of minutes.

Difficulty: Moderately Easy

Instructions

Things You'll Need:

• Screwdriver

Adding a SATA Hard Drive

1. Disconnect your computer from any electrical power sources.

2. Remove your computer's side access panel. This may require removing two thumbscrews on the rear face of the computer's case.

3. Locate a vacant hard drive bay and slide your SATA hard drive into it with the data and power interfaces facing the rear of the case. The drive bays are located at the front of the case beneath the optical drive.

4. Locate a free hard drive bay, and slide your SATA hard drive into it with the data and power connectors facing the rear of the computer case. The drive bays are located near the front face of the case below the optical drive.

5. Locate the two mounting holes on the side of the drive bay you inserted your SATA hard drive into and use your screwdriver to screw in the two mounting screws that came with your SATA hard drive. This mounting helps secure it in place and reduce operating noise.

6. Locate one SATA power connector coming from your computer's power supply, and connect it to the SATA power connector at the back of your drive. The power cable and connector on the drive are both labeled for easy identification.

7. Connect the SATA data cable that came with your hard drive to the second of the two connectors at the rear of your hard drive. Only one end of the SATA data cable will fit to the rear face of your hard drive.

8. Attach the opposite end of the SATA data cable to a free SATA port on your motherboard. Again, this connector will be labeled on your motherboard and is keyed to allow connections to take place in only one orientation.

9. Replace you computer's side access panel and re-establish any electrical connections severed previously.

10. Boot into your operating system and ensure the hard drive is recognized and indeed functional.

Tips & Warnings

• If possible, tie off data and power cables to prevent reduced airflow within your case and promote better component cooling.
• Never add or remove devices from your computer while it is energized, unless the device is specifically designed with that ability. Failure to adhere to this can lead to device and computer damage.
