My Book Duo problems with Mac OS 10.12 (SIERRA)

WD support has given up on this issue and thrown me to the wolves.

  1. the WD Disk Utility once or twice a day says there my there is an invalid raid config on my 12 tb USB duo. When I run the disk utility all seems fine. We have uninstalled, taken it off the logon items and reinstalled. No difference.
  2. periodically the I get a “did not eject correctly” error. Sometimes I have to reboot to get the disk on line and sometimes its just ok.

as of now I have a disk I can’t rely on and no drive utility to manage it or my other WD drive (its a thunderbolt duo).

Any known issues with Sierra?
