NAME
       diskcheck - check a disk for bad sectors

SYNOPSIS
       diskcheck device start count

EXAMPLES
       diskcheck /dev/at0 0 1200
			   # Check 1.2 MB diskette

       diskcheck /dev/at0 100 50
			   # Check blocks 100 to 149

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.
