Corrupt sectors of hard drive

[COLOR="Indigo"]I wasn't sure if a reformat was the right thing to do here. Also, I'm not sure if a reformat will fix things--the knocking sound the drive makes is none too reassuring--and I won't be buying a new external drive for another month or so. I don't want the one I have to be completely useless to me if it can't be reformatted.
