badblock-guess: Data recovery from a damaged disk

badblock-guess will recover all readable sectors of the disk in minimal time while trying to prevent disk read retrying head recalibrations.


It is similiar to:

dd if=<src_dev> of=<dst_dev> bs=512 conv=noerror,sync

but dd(1) solution can last for many weeks/months on heavily corrupted disk.

This program will not recover data of any sector with failing read command. If dd(1) command above finishes for you in a reasonable time, you do not need this program.
