But sort of answering the original question, if it is a corrupted source, then my favourite tool is gnu ddrescue which is specifically designed for recovering as much as possible from failing/damaged media. It's saved the day for me (or friends/clients) many times :-)
Note: always use it with a log file - then it keeps track of what's been copied, what's a "hard" fail, and what's still left to try. You can stop and restart (it'll pick up where it left off), and force it to retry stuff (sometimes, letting a drive cool off will allow a few more bad blocks to be read).

Not to be confused with the confusingly similarly named dd_rescue which doesn't have half the features or abilities.
