#hop over failed blocks on the first run
ddrescue -n $ddrescue_source $ddrescue_target $ddrescue_logfile

#do failed blocks only 
ddrescue -d -r3 $ddrescue_source $ddrescue_target $ddrescue_logfile

make sure you have a logfile.

you do have a disk ready that you've run badblocks on? If not get two disks. 
ddrescue to one and run badblocks on the other. Then when badblocks is done copy 
your files to it and use that disk. Then run badblocks on the othe disk.

About 1:10 disks fails badblocks
