Hi,
I just installed the WD Mybook Duo. My Mac (running Sierra) will detectd the drive, but I cannot see it in the drive utilities, hence there was no way to change the Raid configuration.
I then connected the drive to my Macbook and configured Raid 1.
Connecting it back to iMac with Sierra now shows a 6TB drive (which is correct), but since it is not recognized by the Drive Utilities, I am not sure if the Mac will actually perform the mirroring,
Any advice what I could do to get the Drive Utilities up and running or to check if Raid 1 actually works?
Best Regards,
Sascha
