Recovering Unintentionally Removed Healthy Drives

The NAS supports exclusive RAID recovery technology to recover failed RAID disk volumes from
unintentional disconnection or removal of drives. Users can recover an inactive RAID 1, RAID 5, or RAID 6
volume to degraded mode, or an inactive RAID 0 and JBOD configuration to normal.
