FSCK died with exit status 4

When fsck stops with exit status 4 it means that there has been some data corruption of the mounted volume. Fsck runs when the system starts and if it finds errors it will go into recovery mode from where recovery can be started. Although you may need to run a live cd and then go into to terminal to run one of the following commands. The commands must be run on a unmounted volume or data corruption can occur.

Firstly try :-

sudo fsck – av /dev/xxxx where xxx may be for example sdc1

If this fails try the following :-

sudo e2fsck -f -y -v /dev/xxxx where xxxx may be for example sdc1

If all else fails you can try using gparted and reduce the size of the parition and then resize back to original.

Another option could be installing smartmontools with the following command :-

sudo apt-get install smartmontools

Now hopefully you have a restored filesystem on your troublesome volume.
