If you find them to be useless, then you're wrong. An old computer, after being used for a while, starts to accumlate errors on the harddrive... The sectors with errors on them aren't listed as broken until you run Scandisk, and the computer keeps putting stuff on it. One of my 10 year old computers, an old 300 megahertz one, has half of it's hard drive destroyed due to these errors.
