via built-in hard disk.

there is an error in hard disk.
 Supports RAID 1, 5, 10 and auto restore function when replacing a defective hard disk.

How to deal with a problem occurred?
 If a problem was occurred during RAID operation, RAID manager will appear, and the faulty HDD state
will be changed to Offline or Bad from Online.
 In this case, please turn off DVR and replace the faulty HDD with same capacitor’s new HDD. If you
turn on the DVR, DVR will start rebuilding automatically. Once rebuilding was started, it will keep
rebuilding at background even if you exit the menu. Please note that completion of proper rebuilding
can ensure the reliability of RAID system.
 Please be careful not to replace the normal operation HDD. If you replace the normal operation HDD,
you could lost the data. Be sure to replace the faulty HDD only.
