# badblocks
|
|
|
|
> Search a device for bad blocks.
|
|
> Some usages of badblocks can cause destructive actions, such as erasing all data on a disk, including the partition table.
|

> More information: <https://manned.org/badblocks>.
|
|
|
|
- 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 [n]on-destructive read-write test:
|
|
|
|
`sudo badblocks -n {{/dev/sdX}}`
|
|
|
|
- Search an unmounted disk for bad blocks with a destructive [w]rite test:
|
|
|
|
`sudo badblocks -w {{/dev/sdX}}`
|
|
|
|
- Use the destructive [w]rite test and [s]how [v]erbose progress:
|
|
|
|
`sudo badblocks -svw {{/dev/sdX}}`
|
|
|
|
- In destructive mode, [o]utput found blocks to a file:
|
|
|
|
`sudo badblocks -o {{path/to/file}} -w {{/dev/sdX}}`
|
|
|
|
- Use the destructive mode with improved speed using 4K [b]lock size and 64K block [c]ount:
|
|
|
|
`sudo badblocks -w -b {{4096}} -c {{65536}} {{/dev/sdX}}`
