how to check a filesystem in Ubuntu 16.04?

  • 772

In Ubuntu 12.04 I was used to run the 'Disk Utility' and choose 'Check Filesystem'; its subtitle showed also 'and repair'. In Ubuntu 16.04 I have only found the 'Disks' utility that looks similarly but has no 'Check Filesystem' option, even for the superuser.

16.04

    To check the file system on your Ubuntu partition...

    • boot to the GRUB menu
    • choose Advanced Options
    • choose Recovery mode
    • choose Root access
    • at the # prompt, type sudo fsck -f /
    • repeat the fsck command if there were errors
    • type reboot

    If for some reason you can't do the above...

    • boot to a Ubuntu Live DVD/USB
    • start gparted and determine which /dev/sdaX is your Ubuntu EXT4 partition
    • quit gparted
    • open a terminal window
    • type sudo fsck -f /dev/sdaX # replacing X with the number you found earlier
    • repeat the fsck command if there were errors
    • type reboot

  2. Just some comments:

    1. To enter the GRUB menu press and hold SHIFT while booting
    2. In Recovery Mode better to choose "fsck - Check all file systems", see picture.
