Do you have partitions mounted at /tmp, /usr, /var etc? Does the output
of your du command change if you unmount those partitions?
(It might be an idea to boot into a livefs CD or DVD given that du(1)
lives in /usr/bin, so a bit tricky to unmount /usr and then run du)
My guess is that you've at one time created files beneath what is
usually a mount point. Mounting the partition over them makes those
files inaccessible, but they still take up space on the drive.
Cheers,
Matthew
