I just purchased a new “My Passport Ultra” 3TB external drive and when I plug it into my laptop (Windows 7 service pack 1) using the USB 3.0 (compatible with 2.0) cable, it just spins for a minute or so and then stops. I keep waiting for the driver setup screen but nothing ever shows and when I open up My Computer, I don’t see the drive listed anywhere.
I tried plugging in when the laptop is already booted up. I tried plugging it in and then booting up the laptop. Same results both times where it just spins and then nothing.
