If a modern hard drive begins to show bad sectors it generally indicates it is in its final death throws and it is better to just replace it and not try to make it limp along. Most modern drives reserve 'spare' sectors that are automatically used to replace bad sectors. You don't start seeing bad sector messages until those spare sectors are used up. So, that implies there there are already even more bad sectors on the drive than it is telling you about. So, don't try to be penny wise only to be dollar foolish. Get as much of your date as possible on some backup media and throw away the bad drive and get a nice big new one.
