Software drivers that support write buffering can be turned off. If
it happens in the drive itself... I'm not sure if the drive has time
from reset or power down to write out its buffers. Odds are it will,
sometimes it won't I guess. I would'nt keep a file open for hours at
a time myself.

The problem is when it takes the whole file system along with it.
In my Linux installation notes, I'll at least recommend that
there be a TASS partition seperate from the "rest" of Linux. It
would not be out of hand to have a "data" partition I guess, wiser heads
will have to be scratched on this.
