A spare drive can be added to RAID 1, RAID 5, RAID 6, and RAID 10 volumes. Before adding a spare hard drive,
you must follow the instructions above (Custom) to create the RAID volume. When creating the volume, leave
a minimum of one hard drive free for the spare. For example, a four-disk RAID 6+spare would require that you
