A hard drive is nothing more than a magnetised storage area. Your Operating System is stored on your hard drive, as well as all your software programmes, like Microsoft Word. The hard drive is actually a few circular disks stacked one on top of the other. A little arm moves over the disks and writes things to these circular platters, and reads them.
So a 320GB hard drive has 320,000,000,000 bytes (or so). To your computer's operating system, a GB is 2^30 bytes (1,073741824). So it will report as about 298GB. I'm not sure if that answers your question, but your question isn't precise enough to answer completely.
