I have no clue regarding all things in Terminal, Darwin, Linux, Unix, Ubuntu, etc. and am trying to figure out how to run a dd_rescue in the Terminal to save an external hard drive that is my only clone of some very important info. Has anyone here used dd_rescue on OSX? If so, how the heck do I set it up in the Terminal? I've already ran dd if= on the drive, and it stalls out halfway through. Grr.. this is taking up my whole weekend!
