Mechanical sounds coming from the hard drive can't be fixed with software..
purchase another drive at your earliest convenience, and use the trial
version of Acronis TrueImage to clone the contents from one to another..

HD diags supplied by the manufacturer that are not 'destructive', that is to
say leave your data untouched, do not always pick up on faults.. the low
level format (writing zeros) will remove everything from your drive, but
will show errors that the other tests miss..
