As a general rule of thumb, I only use gnu rescue for that purpose (making a disk image backup), since it works around "hard errors" better than most. I have used dd_rescue before (similar but different utility), as well as dd (which can make a sector by sector copy, but doesn't work around hard errors) But, I only use them under LInux and I don't normally use Windows programs for that purpose (and the Windows utilities I've tried in the past "choked" on hard errors with failing media).
