- DESCRIPTION
- Diskcheck checks a disk for bad sectors by reading in each sector,
- writing a known bit pattern onto it, reading it back in and comparing
- with what was written. This check is then done a second time. Bad

- is restored. Only use this program on unmounted partitions. Killing it
- part way through may result in lost data.
