How to rebuild RAID
(1) Find the bad drive. Eject and power off the enclosure in order.
(2) Pull out the bad drive. Format the new drive on another device first. Then insert the
new drive ( the same capacity or bigger ) to the original position and turn on the
enclosure.
(3) You can download our Software RAID Manager on our Website. Note: this step is not
necessary.
(4) The enclosure will start rebuilding current raid mode automatically. The light will
