Note: In RAID1 mode, if one of the drives fails, the Red LED to the right of the hard drive tray will
blink. Replacing the drive will cause the enclosure to automatically enter rebuild mode, in which
the Red LED will continue to blink to indicate that the RAID1 array is being rebuilt. Depending on
the size of the drives, this may take several hours to a full day.
