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}}
