No no no!

Do not use ``dd''. DD is not the tool for data recovery, because it
stops on the first error, and if you try again it will stop at the
same point. What the OP needs is a tool that continues on errors, and
logs where the error occurs so that it doesn't have to retry next
time. This tool is ``ddrescue''.

GNU ddrescue replaces the older gddrescue (or dd_rescue) command.

There's a howto here:
