External USB 3.0 drive "your drive needs to be formatted before use" loop

I have a 2 Tb Western Digital my book essentials that I have been using to back up my Win 7 pro HP laptop since July of 2013. Sunday morning during my weekly backup we had a power failure and the my book was not on an UPS and I received a message in win 7 backup that the drive failed to write. If I plug the drive into the same usb 3.0 port that it was plugged into at the time of the power failure, I get a number of " your drive needs to be formatted before use" messages and when the loop finally stops the drive does not show up in Windows explorer or in disk management. If I connect the drive to a usb 2.0 or different usb 3.0 port on the same computer, the drive shows up ok and appears to function properly. Does anyone know how to "rehabilitate" the usb 3.0 port that now will not recognize the drive after the 5 or 6 this drive needs to be formatted messages? I realize some would say don't worry about it, but I would like to be able to use my external drive in any of my usb ports. Thanks for any help that might be available.
