This is more or less also what (GNU) ddrescue does[0]. It first tries to do a linear copy of the full disk, skipping any errors, then goes back and tries to re-read the error sectors until you either cancel or it succeeds. It also keeps track of everything it's doing so you can stop and start the process without it redoing work.
