Rebuilding a RAID hard drive

Introduction
In RAID level 1, two equal-capacity disks mirror one another. Both drives

disk. If one drive fails, the other continues to run. When the failed drive is
physically replaced with a new one, the data on the operating drive of the
system pack must be copied onto the new drive to rebuild it. RAID
automatically performs this rebuild process when the replacement drive is
accessed.
If you want to start the initiation process sooner or monitor the rebuilding
