The drive you want to check must be unmounted or the check itself may corrupt the filesystem!!


sudo fsck [options] [device name]

Useful commands

These require sudo.

To list mounted drives:


To mount everything in /etc/fstab:

mount -a

To list all recognized drives and partitions:

fdisk -l

To reboot, forcing fsck on root filesystem:

shutdown -rF now

To fsck all unmounted filesystems with pass number > 0 in /etc/fstab:

fsck -ARM

To pretend fsck:

fsck -N

To make fsck skip mounted filesystems and exit cleanly:

fsck -M

To fsck a broken filesystem, automatically answering "yes" to prompts:

fsck -y
