I've regularly used dd on drives, but not on ones that were in trouble (maybe once ...) But now drives are at the point that you cannot guarantee an error-free scan even on just one pass, I guess I'll have to make sure I use ddrescue from now on - I usually just read an (old) drive into a file on a new larger hard disk, loopmount it, and proceed from there ... never had any trouble so far ...
