There is nothing preventing someone from first creating a protective partition, similar to the MBR record used by GPT. Then they would be able to use the 4k offset 1.2 label on the device if they absolutely wanted. However a normal MBR with partition and 1.1 label would use less disk space and be more compatible with other tools. Similar logic applies for GPT labeled drives, and any drive large enough to require GPT should not miss the ~16 kilobytes required at each end of the drive. -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
