The software does notice if one of the two drives fails and indicates it to you with a light on the front of the unit. Each of the two drives is very easily swapped out with a replacement and the unit will detect the new drive and ask if you want to mirror your remaining drive data onto the new drive. If one of the drives is dead, the second will continue to work, but without the extra layer of backup protection offered by the RAID mirror feature.
