NOT a good idea. I don't know what it would do in your case, where you
are using the entire disk, but if you're using a partition table you
would suddenly end up with a bunch of duplicate GUIDs. Bearing in mind
the "GU" stands for "globally unique", your management tools are likely
to get confused ... not a good idea especially wrt raid.
Cheers,
