  • Search a disk for bad blocks by using a non-destructive read-only test:
    sudo badblocks /dev/sdX
  • Search an unmounted disk for bad blocks with a non-destructive read-write test:
    sudo badblocks -n /dev/sdX
  • Search an unmounted disk for bad blocks with a destructive write test:
    sudo badblocks -w /dev/sdX
  • Search an unmounted disk for bad blocks with a destructive write test and show verbose status:
    sudo badblocks -svw /dev/sdX
  • Search an unmounted disk in destructive mode and output found blocks to a file:
    sudo badblocks -o path/to/file -w /dev/sdX
  • Search an unmounted disk in destructive mode with improved speed using 4K block size and 64K block count:
    sudo badblocks -w -b 4096 -c 65536 /dev/sdX
