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
|
|
sectors are reported. After each sector is tested, the original sector
|
|
is restored. Only use this program on unmounted partitions. Killing it
|
|
part way through may result in lost data.
