dd will stop at bad sectors. try the ddrescue tool instead.

Description: copies data from one file or block device to another
  dd_rescue is a tool to help you to save data from crashed partition.
  It tries to read and if it fails, it will go on with the next sectors
  where tools like dd will fail. If the copying process is interrupted
  by the user it is possible to continue at any position later.
  It can copy backwards.
