So, I have a Dual MyBook drive that doesn’t have HDs in it. I have two 2000GB Seagate Barracuda drives. When I put both drives in, they will not mount. When I leave one in, on one side it mounts and I can erase/initialize it. When I take that out and put the other one in, on the other side, I can erase/initialize it also. But when I put both in, my Disc Utility won’t see them, and my WD app sees a drive but I can not do anything with/to them.
Do I have to set them up a certain way for them to be seen?
Any help would be greatly appreciated!
