        Oh. Has this ever worked? I seem to recall there were some things
you couldn't do, though I admit I can't remember what at the moment. I do
remember getting RAID1 working over RAID0 at one point, though I seem to
recall you weren't able to do the opposite. I've got a couple disks here, I'll
try your configuration and see if I can get it to work here.
