Yes, the power-down is quite amusing with ext3.  Sometimes when I'm doing
something that runs in memory, so I don't need the hard drive, I hear the
hard drive power down.  Just as I'm thinking "at last, some peace and
quiet", about 15 seconds later it powers up again.  I guess that must be the
journal getting written or something.
