My Book Studio 4TB USB3 keeps ejecting from New Mac Pro

I had a USB3 My Book Studio plugged into a Mid 2010 Mac Pro . When I upgraded to the New Mac Pro last week , I was excited to get the increased speed of USB3 . However , the drive is constantly ejecting itself . I have serached forums all over the net and this seems to be a common problem. I have shut the sleep functios off from the drive and the computer, to no avail. Please can someone help. Many Thanks.

Hello,

Make sure the drive is plugged in directly into a wall outlet. Sometimes an extension cord, power strip or surge protector are the cause of this issue.
