WD 6TB MyBook Duo

My drive has suddently started reported intermittent errors. The Drive Manager icon will sometimes start flashing red, with the alert “Raid Status - No Config”. Other times it will tell me the drive is bad, or sometimes both drives are bad. Then the alerts vanish.

But there is a problem - some files I am unable to copy to another drive as they cannot be read. Read Errors etc.

The Finder can’t complete the operation because some data in “37b.png” can’t be read or written.
(Error code -36)

Does anybody have any suggestions?

Thanks in adance.
