If you look around theres actually stuff for that in existance now. The current ex2fs keeps a UUID on each volume which is basically there for just that reason (UUID's are statistically unique keys for objects - there's an RFC for the UUID system too)
If you have an Ethernet card, (and the manufacturer of the Ethernet card was competent about assigning Ethernet addresses --- some weren't, unfortuantely), the guarantees on the uniqueness of UUID's is much more than statistical, actually.
