on the workstation I had at my previous job (VAX 3100 w/ Ultrix 4.2), I
never saw damage that fsck couldn't handle when the machine rebooted.
but....the first time I saw a UNIX machine (albeit a pitiful excuse for
one) have the rug pulled out from under it, there were no survivors....
it happened over Christmas vacation at my previous job, my first year there.
I had a ps2/80 running aix (YUCK!), and someone apparently walked into my
office and said, ``oh, Jim left his pc on...better turn it off for him....''
I came back to find a dead filesystem.

this is true....but since I can't use my tape drive (yet...it's coming),
that's kinda tough to do. :-( once there is a working QIC-40 driver, you
can bet that I'll be doing very regular backups.
