To me dd's noerror flag as well as seek are very comforting to know of whenever I'm on a quest to preserve some precious data from any medium currently in failure mode ... any extra read might be your last.

dd is a beautiful little swiss army knife and I'm not ashamed to be part of the "cult" lol. I have had to use ddrescue too though. It's handy to have in the toolbox if you have a disk with errors and want to get data off of it.
