In this case, the HDD in drive bay 2 can be used continuously without being replaced.
Perform the following procedure to recover from this state:
1. Back up your data.
(See (2) Backing up files in 4. Hard Disk Drives (HDDs) and Solid State Drives (SSDs) in PRECAUTIONS.)
2. Execute the following command at the command prompt as an administrator:
C:\> raidctrl /REBUILD
3. The HDD status lamp blinks after a while and RAID1 rebuilding starts.

status of both HDDs is normal.
NOTE
Rebuilding is also enabled by using the software RAID utility. To rebuild RAID1 by using the software RAID
