Candidates for DFA are those disks that come up "damaged", "unreadable", or "not a Macintosh disk" when inserted into a drive. When you see one of these messages, it's time to bring out your favorite sector copier and duplicate the disk. Don't use bit copy mode; it's too good and just transfer errors. MacZap Recover HFS 5.0 (now Symantec Utilities for Macintosh) is the next best bet if DFA fails. However, when DFA works, it works *well*.
