My cloud home pending drive

I have a my cloud home. And recently i got a 2nd drive show up in my computer and wd discovery, and it says its pending. How do i remove this? WD is refusing to fix.

Uninstall WD Discovery and restart My Cloud Home device, then reinstall the updated version of WD Discovery from WD Support. Then you should be able to see second drive in WD Discovery.
