	One thought: find "raidreconf", now part of the raid tools package, I
think.  It can "export" from a RAID5 to a single disk.  The RAID must be
shutdown/offline, and it runs entirely in user space.  You'll still get
errors, but what it can read, it will.

	Again, this is just an idea.  It may work, and it may not.... :-(

	Caveat: I wrote the RAID5 code, so beware! ;-)
