Since anyone can remount it RW, it isn't always necessarily RO, but
mdrive_fstab file obviously got blown away somehow.  Someone might have
remounted it RW for some reason a while back, and forgot, and a crash
days later might have had a negative effect.  But mdrive_fstab is never
written after it is layed down, so it shouldn't ever be harmed by a
crash/fsck event.  BSD.  'Nuff said.
