du -hs /tmp

du -hs /
40GB

One thing that comes to my mind. Each Sunday I have a script which
makes a full dump of the HD to a back-up USB drive. Last weekend
someone cleaining the computer room, must have accidentally powered
off the USB drive. As a result, the dump has not been completed
because the USB drive was not mounted at that time. I use cron for
this task. Does it matter could have caused this?

Thanks!
