Well, you only need to leave room for 512 bytes or one hard drive sector,
in the case of gmirror.

I've never seen a drive that ends exactly on a cylinder boundary;  hardware
RAID assumes this too.  I would like to hear of a drive which is an exact
cylinder multiple and how hardware RAID handles those situations.  I always
just assume there's extra space that's not consumed.
