Grub doesn't support "disk-ids". It either uses the old ordinal system ( hd0 ) or searches for the fs by uuid. If you make a byte for byte copy of the disk and remove the original disk, the new one will boot fine because it will still find the root fs having the same uuid. That takes me back to the question of how are you duplicating the disk?
