... I've used one but not the other (I think it was dd_recover) and it
is essential for what you're trying to do here.  I was able to set it to
try a fixed number of times to try to read a bad block and then just
continue to the next block without ending the program.  It can also do
repeated sweeps of the HD and progressively build up the image.  The
latter is particularly useful if the problem(s) you have are
intermittent and/or if they "move".
