Running out of disk space is a common problem to have if you download a lot of programs, MP3s or movies to your computer. For most current PC owners, the easiest method of adding more hard drive space is to add a second hard drive to your system. But before you install such a drive, you'll need to prepare yourself for the inside of your computer:

- Turn off your PC, unplug it, and open the case. Most PCs have at least one open drive bay. Unless your computer is already stuffed to the gills, you should have enough room to add a second hard drive. If it is stuffed to the gills, you’ll either have to upgrade the current drive or add an external FireWire or USB 2.0 drive. Slide the new drive into the bay and connect the ribbon cable connector to the 40-pin slot on the hard drive. The power supply cable has a connector on the end of it, usually four sockets encased in a small sheath of white plastic. Plug that into the connector on your hard drive.
