How to Install an Internal Hard Drive on a Desktop Computer

Sometimes it's necessary to install an internal hard drive on a desktop computer. A bad hard drive may need to be replaced, or maybe you want to upgrade to a larger drive. Installing an internal hard drive is not that difficult. Learning how to do simple upgrades and repairs will save you a lot of money. Here are a few steps to help you safely install an internal hard drive on your desktop computer.

Difficulty: Moderate

Instructions

Things You'll Need:

• Computer
• PC owner's manual
• Anti-static wrist strap
• Hard drive
• Operating system

1. Back up your data. If you are replacing an existing hard drive that is still functional, back up any important data that is stored on the drive. If you are selling or giving the original hard drive to someone else, erase any data on the disk by formatting it.

2. Open the computer case. Remove any metal rings, watches or bracelets you may be wearing. Unplug the computer from the electrical outlet, then touch the metal casing to eliminate any static charge. You can also use an anti-static wrist strap if you prefer. Refer to the owner's manual if necessary to determine how to open your particular desktop computer case.

3. Remove the original hard drive. Typically the hard drive will be connected to a flat 2 1/2-inch-wide IDE cable and a power cable. Hard drives are often housed in removable metal cages which are secured to the case with one or more screws. If not, the hard drive will be attached directly to the case. Refer to your owner's manual to locate the hard drive.

4. Install the new hard drive. Refer to the instructions that came with the hard drive to adjust jumpers if necessary. Connect the existing IDE and power cables to the hard drive. If the drive is housed in a metal cage, place it in the cage, replace the screws and reattach it to the case. If the drive connects directly to the computer case, slide it into place and then replace the screws on each side of the hard drive. Replace the cover, then plug the computer back into the electrical outlet.

5. Format the new hard drive. Restart your computer and follow the instructions in your owner's manual to enter your system's BIOS. If the hard drive is installed properly, it will be recognized by the BIOS. Load your operating system CD into the CD ROM, reboot the computer, then follow the instructions on the screen to format and install your operating system. Once the operating system is installed, transfer your personal data to the new internal hard drive.

Tips & Warnings

• Always store functional hard drives in anti-static bags when not in use. If possible, also enclose them in a layer of bubble wrap while in storage.
• Hard drives are very sensitive to cold, heat and jarring. Be careful not to hit, bump or drop the hard drive when removing it. Also, do not bend any of the pins when connecting the cables.
• If your PC does not recognize the new internal hard drive it may be defective. Keep your receipt in the event it has to be returned.
