It is indeed a bit strange to have a major FS corruption without preceeding
symptoms (eg. messages).
It looks as if your drive has a big cache and don't flush it properly (but
reports a successful flush back to OS). So from OS point of view everything
seems OK, but F/S corruption becomes visible upon the next power-on. Just a
guess. Could be anything.
I would suggest following David's recommendation. (AIUI you won't install the
diagnostic tool. You boot it from CD/USB and run it stand-alone.)
