No: the 'mirror' system isn't a real mirror - the file systems are
configured identically, but it's up to me to manually copy data between
the two. So the bottom line is we've lost about a weeks worth of
experimental data from the lab (since that's the last time I did a
copy.) Not the end of the world, but I'd like to recover from this if
possible.

I was really asking if this approach makes it possible to recover a disk
in it's entirety, rather than sorting through the recovered data to
extract each file separately. (It seems to be just the latter, from
what I gather reading quickly through those webpages.) And if not, then
would it be possible for an fsdb 'expert' to get the disk back up and
running? I'd be willing to pay someone to do that if they could...

Do you think my suspicions about overwriting /etc/mnttab could explain
what happened? The disk was working when I shut the system down, and it
was only upon reboot that the OS couldn't fsck the disk...
