Try resetting the SMC.

I have one of those drives from 2 years ago and it's fine. I just ordered a new one. I'll find out Thursday if there's a problem with the newer model.

After stumbling around on utube I finally went to WD website, support. They showed me some settings I was not aware of on disk utility. Followed their directions and EUREKA! solved. Thank you CountryGirl56 for your support. I have saved the (SMC) reset info for the future.

They probably told you that you have to format the drive at the device level not the volume level. If they told you something else it would be good for you to post what they said so others may benefit from what worked for you.
