Below each window there is a Capacity window that will display the size of the
available drive, or of the mirror drive. Each drive that participates in a mirror
should be of equal capacity. If you select a drive that has a greater capacity and
add it to the mirror, the mirror capacity will still be the smaller of the two, and the
rest of the capacity of the larger drive will be unused. For example, if you added
a 18 GB drive to the mirror in Figure 5-20, the Mirror Capacity window would still
show the capacity of 8,696 MB. Approximately half of the 18 GB drive will be
unused.

dedicated spare drive to the mirror if desired. Highlight one of the remaining
available drives, click Add>> and its name will appear in the Mirror Drive
Dedicated Spare window, as shown in Figure 5-21.

system to write its signature on the Mirror drive.
