cd /bad_partition && dd if=/dev/zero of=big_file.zero bs=512 conv=sync,noerror Let it run until it finishes. That won't explain why the sectors are bad, but it may give a good indication of the problem area and answer the failing drive question. If dd reports IO issues, you may want to replace the drive.
