How can I confirm that the D2-320 has successfully entered RAID 1 mode?

Applicable Models

D2-320

Taking two 1TB hard drives as an example, check the recognition result in the computer's Disk Management:
RAID 1 mode: Displays as a single 1TB disk (mirror mode)
Comparison with other modes:
SINGLE: Displays as two independent 1TB disks
RAID 0: Displays as a single 2TB disk
JBOD: Displays as a single 2TB disk

If Disk Management shows a single 1TB disk, it indicates that RAID 1 has been successfully enabled.
