How to Remove a Compaq Hard Drive

By Jack Gerard

Pre-built computer systems are designed to include everything that you will need to have a functioning computer right out of the box, but there are a number of aftermarket components and upgrades you may want to add to your PC. Though the specific components may vary from one model to the next, Compaq computers are generally quite easy to perform a number of upgrades on. One of the most common upgrades, replacing a hard drive, requires that you first know how to remove the old hard drive. You can perform this simple task within a few minutes so that you'll be able to install a new hard drive with ease.

Things You'll Need

  • Screwdriver (Phillips head)

Step 1

Shut down your Compaq computer, unplugging it from the wall to ensure that it won't accidentally be turned on while you're working on its internal components. After the computer has been unplugged, depress the power button once in order to discharge any electricity that might be held in the power supply or any other components.

Step 2

Remove the screws holding the left side panel of the computer case in place. Depending on the model of your Compaq PC, you may find thumbscrews in place of standard Phillips-head screws. These may easily be unscrewed as well. Depending on their design, however, you may not be able to remove them completely. Once the side panel is no longer in place, slide it back to remove it. If it still won't come lose, make sure there isn't a retaining clip. Look for a black plastic or rubber piece on the back of the computer next to the panel which can slide down. Set the panel aside.

Step 3

Lay the computer on its side carefully so that you can have easier access to the inside of the computer. Locate the hard drive in a 3 1/2-inch mounting bracket beneath the computer's CD and DVD drives. If your Compaq computer has a floppy disc drive as well, the hard drive will be mounted beneath it.

Step 4

Disconnect the two cables plugged into the back of the hard drive. One will come from the power supply while the other will be the motherboard's data cable and will either be wide and flat or thin and red. Move the cables out of your way, making sure that they will be convenient to plug back into your new hard drive once it is installed.

Step 5

Unscrew the two small screws that hold the hard drive in place. Set them aside so that you'll be able to use them to mount a new hard drive into the mounting bracket when you are ready to install it. Once the screws have been removed, all that remains to do is to slide your Compaq computer's hard drive out of the bracket and set it aside.
