My Book Live Duo solid red LED "Data volume failed to mount" error

Sudden red LED light noticed after power outtage earlier same day
"Data volume failed to mount " error message on Dashboard browser.
Passes quick test on utility menu

Is in mirrored configuration.

Should I assume that I need to replace the enclosure?

are there any other checks that I can do myself?

many thanks


It means the RAID volume itself has been compromised. Replacing the enclosure may not help.

You will have to rebuild the RAID array.
