What problem are you needing to fix, first? What happened leading up to this problem? What steps have you taken so far? Is this Vista or XP?
No offense is intended here, so please don't construe this to be anything but an attempt to get straight to the point.
I know how to troubleshoot, I did tech support for several years. I am looking for a hard disk repair/check utility because I believe that I have a hard disk problem, probably a bad sector or sectors.
