How do I tell which drive has degraded? Mybook Duo

WD External Drives External Drives for PC

Hi,

See attached screen, I have a WD mybook Duo and I am suddenly receiving this warning.

Do I need to replace one of the drives and rebuild, if so which one (i see no indication)?

Should i just hit “Rebuild” but will I lose my data?

Hi,

I have read through your link but it doesnt provide the answer to my questions as BOTH drives are still displaying “Online” status however I have a “degraded” message and the duobook external light is now orange. There is nothing to tell me which drive is degraded. What do I do next?
