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 any damaged blocks:

sudo e2fsck -p {{/dev/sdXN}}

  • Check filesystem in read only mode:

sudo e2fsck -c {{/dev/sdXN}}

  • Perform an exhaustive, non-destructive read-write test for bad blocks and blacklist them:

sudo e2fsck -fccky {{/dev/sdXN}}
