>From what sdavmor and Preston said, it seems as though I should plug
it into a Windows machine and run chkdsk on it. I do have an old XP
machine that still works properly, so I suppose I'll try it on that. I
suppose I need to go into Start - Accessories and find chkdsk in there
somewhere. Probably not too hard.
If I do that, about how long should the chkdsk take? It's a 700 GB
hard drive, with about 600 GB used. Will it need to run overnight?
