dd_rescue (or ddrescue) will image the drive and retry bad sectors
several times to get the data.

first, grab most of the error-free areas in a hurry:

ddrescue -n /dev/source /dev/destination rescued.log

then try to recover as much of the problem areas as possible:

ddrescue -d -r3 -f /dev/source /dev/destination rescued.log

*got a message that says "Output file exists..." so used "-f" after the
command to force.

Good luck!
