Default ext4-fs error

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Hi!

I've been lately getting an error message saying "unable to mount (one
of the external USB harddrives) some time during the night when the
computer has been running. I'm able to manually umount and remount the
drive in question. At 9:48 did I manually mount the drive.

This is what I found in the kernel log:

Is this a sign of an ailing harddrive about to give in?

Did you run e2fsck on this partition? What Ubuntu version are you
running?

Hi!

e2fsck said "bad superblock" when I first tried. I used gparted to fix
the drive after unmounting it. That seems to have done the trick.

Still try running e2fsck in the style:

e2fsck -fvy /dev/sdx1


at your partition /dev/sdx1 while unmounted.
