If you get a hard failure, you may want to try dd-rescue on it.  That
will work around "holes" in the data and continue to recover data.  It's
what I use for hard drives, though I don't know how well it will work on
USB flash drives.

And YES!  Absolutely!  Always make the best backup copy you can before
attempting any recovery and then only work on the image.  Do not burn
your bridges.

Mike
