WD Model 3200i032 and Sierra

I have a mac desktop and have not connected to my WD since I updated to Sierra. My computer is not recognizing the drive at all. I have no idea what to do. Is there someone who can give me some clues. I plug it into the back of my computer, the little white light is blinking and nothing happens.



What connection are you using?

Is the power cable connected to the wall outlet?
