Music Disappears on MyCloudMirror

I’m using My Cloud Mirror as storage for my Itunes music. Sometimes the music disappears and can not be found.
My Cloud Mirror is not shown in Disc Tools but in Finder.
There’s no pattern in when the music disappears, some days nothing happens, other days several albums disappears.
I have approximately 800 GB music stored, hope not all one day is gone.

Hello,

Do you have any other files on that drive? Anything else missing?

What firmware are you running on the unit?

Please check that you don’t have the WD Sync running on your computer and some one is removing the files from the computer.
