Takes for ever though but is easy to use and may recover partial sectors automatically too ;-) Free but harder to use tools are ddrescue, recovers as much of damaged sectors as possible. mhdd comes with sysresccd and can make a drive ignore bad sectors independent from the filesystem. Be careful to get the right sectors though as it will destroy the data in them. If the drive has a bad sector because it got knocked then it's probably all good to keep using it. If you get any more then your heads crashing and you need to replace it quick.
