  • Power down PC, unplug power. Open the PC, determine type of hard drive connection, most likely IDE. Buy similar drive.
  • If your old hard drive is bad, remove old HD (need screwdriver). There should be a diagram on both hard drives showing where to place the jumper. Look at this and then place the jumpers on the hard drive, matching the new one to the old one (usually located in the back by the ide/sata and power plugs) to match the diagram. Cable select is usually the right choice especially if there is only one drive on a cable with only one connector at each end.
  • Recomended drive: 7200 RPM or greater, 2MB Cache or better
  • Make sure you get the same type hard drive - PATA (IDE) or SATA - as you old one, unless your motherboard does both.
  • While your case is open, blow out the dust. It improves circulation and can add to the life of your computer. Also make sure all the fans are working. Leave the case side open and turn it on without touching the inside. All the fans should come on, assuming you have a name brand computer (read: bottom-line for company) without thermostat controlled fans.
  • The first part is a matter of cloning the hard drive (assuming you are not just moving the disk from one computer to another). Otherwise the process is known as a repair installation where you will need the bootable CD with the OS to fix the old hard drive so it works in it's new home hardware.
