You might try ddrescue (in the ddrescue package) which is dd with better error
recovery.  It will can try reading bad sectors multiple times to see if it can
get a good version although that is more usual for failing hard drives.

Also, it can write the bad blocks as zeros and read the rest of the files.  If
you can get a partial .iso, rsync and bittorrent can fill in the holes without
having to download the parts you already have.
