My Book Duo Error Message, Then No Error Found

[ajackuk]

I have installed the My Book Due on my iMac running Yosemite.

Installed the Mac software off the WD site, configured it for RAID and is working quite well - very happy with it.

However - on 3 occasions in the 2 weeks I have had it, I had a pop-up message that there was a problem with the RAID and prompted to run the diagnostics.

Run them and find no error.

Hello and welcome to the WD Community,

Have you tried reinstalling the WD application?
