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?
