Have you tried plugging into a different usb port, or to another computer?
Another method is to remove hd inside your MyBook and connect it directly into your computer.
Yes, I moved the hd plug to a different USB port on the laptop. same problem
I will try connecting the MyBook to another computer to see if that makes any difference. I'd prefer not to have to remove the HD from its case, and all that.
But, I may have to.
