Moving files from bad external harddrive I use OSX mavericks. My external 1TB harddrive is partially unreadable. I want to salvage its content as much as possible. I have tried dd but it took almost a day, so I killed it, and it could not resume from where it left when I rerun it.
I am currently trying moving folders one by one with Finder.



My question is there any option in Finder to continue moving even if errors are detected ?
Finder will always halt on Error. 
Have you tried Data Rescue 3? I've had good results using that in the past.
