I considered wasting some space outside of the partition on each disk to give them different sizes (500k would do it) but that feels really hacky. :) I'm experimenting with another solution, and if I make good progress, I'll report as such.

See the thread at
http://www.gossamer-threads.com/lists/mythtv/users/280805#280805 .  Note
that Chris Pinkham (one of the responders in that thread) is the author
of the code that identifies the "unique" disks (and the rest of the
Storage Groups code, too), so his posts are a bit more than armchair
quarterbacking.

There, we agreed that a false positive test for uniqueness is /far/
better than a false negative test.
