# e2fsck
> Check a Linux ext2/ext3/ext4 filesystem. The partition should be unmounted.
> More information: <https://manned.org/e2fsck>.
- Check filesystem, reporting any damaged blocks:
`sudo e2fsck {{/dev/sdXN}}`
- Check filesystem and automatically repair ([p]reen) any damaged blocks:
`sudo e2fsck -p {{/dev/sdXN}}`
- Check filesystem in read only mode:
`sudo e2fsck -c {{/dev/sdXN}}`
- [f]orce checking even if the filesystem seems clean:
`sudo e2fsck -f {{/dev/sdXN}}`
- Perform an exhaustive, non-destructive read-write test for bad blocks and blacklist them:
`sudo e2fsck -fccky {{/dev/sdXN}}`
