In this tutorial I will guide you through the process of installing a Serial ATA hard drive into a desktop computer. Installing a new hard drive into a computer is a very common and, most of the time, easy thing to do. With the cost of hard drives so low right now it is a great idea to add a second drive or upgrade your current drive to larger size. With more and more people storing all their photos, music and videos on their computers it’s a good idea to always get the biggest hard drive (within your budget) available so you don’t have to keep upgrading every two years. Let’s get started.


1. The first step is to find out if you have any room in your desktop computer for another hard drive. If you are replacing your current drive then you can move onto the next step.

2. Find out how your hard drive fits into your computer. Most computers use four screws that go into the hard drive’s side and then you slide the drive into your desktop. Some computer cases have screw less systems that require you to attach a bracket to the hard drive and then slide it into the case.

3. All desktop computer SATA hard drives have two connectors. The longer “L” shaped connector is for the power and the shorter “L” shaped connector is for the data cable. If you are adding a second hard drive to your computer then you will need a SATA data cable and an empty SATA port on the motherboard. You’ll also need a free power connector from your power supply.

4. Make sure that your power supply and motherboard can support a SATA hard drive. If you power supply doesn’t have a SATA connector then your can by an adapter for cheap, but if your motherboard doesn’t have a SATA port then you can’t use a SATA drive.

5. Attach the SATA data cable to the SATA connector on the motherboard. Then make sure to arrange your power supply cable to accommodate the new drive.

6. Place the hard drive into the computer case and make sure it is securely fastened.

7. Attach the power cable and the data cable to the hard drive and then you’re done. Just power on your computer and your ready to go.


– Always make sure to unplug the power cable from the computers power supply before installing a new SATA hard drive.

– If you have two hard drive attached in your desktop you might have to go into the BIOS and change the primary drive to the correct hard drive.

– In some computer, mainly HP, the first time boot up the PC you will get a warming message saying that the system has detected a hardware change. Just press F1 or continue to get past this warming. You will only see this warming once.
