I was able to get around this issue by taking the WD Drive Manager service and making it a Manual operation, instead of Automatic. You can always try this out. I have 2 different WD drives a Passport and a My Book, the My Book was unrecognized when I added the Passport. Took me quite a while to find the issue on my PC, turning off the WD Drive Manager service and let Windows handle it. Best of luck on this.
