Issue:
AMD RaidXpert Service gives an Raid 1 array “error” stating a single disk failure. One of the two drives in the Raid 1 array becomes a JBOD standalone drive, basically detached from the array for whatever reason. The drive is still listed as healthy and SMART scan does not show any issue either. It is simply “assigned as JBOD” under “Logical Drive View” in RaidXpert. The problem is, the “Rebuild” tab is greyed out and unusable. You can only see the failed array listed as “Critical”, one of the two drives is still mounted as part of the Raid 1 array, but the other drive is now JBOD.
Solution:
Make sure that you have boot into the remaining Raid 1 drive and NOT the JBOD drive if the array was your system drive. Start RaidXpert in Windows. After you have logged into RaidXpert, click “Logical Drive View” under “AMD RAIDXpert” -> “Logical Drive View”. Under “Logical Drive View”, and to the right of the screen you will see “Delete” as a usable tab. Click on it, and then select “JBOD” drive and click “Submit”. Once that’s done, the Rebuild tab would appear. Now hit “Rebuild” and the process will begin. And you are set.
