laptop hard drive recovery...
so my friend lost a bunch of data recently so he had to reformat his hard drive. I had him check for errors on the hard drive and it basically just gets stuck half way through. He also has ran recovery programs (not sure which ones) and found the files but they won't let him recover them. So my question is one: can he just block the sector that is bad of the hard drive and two: know any really good data recovery programs?
