Hello!

I recently bought a new Mac mini and Seagate goflex 3TB external hard drive. The computer is awesome but if I have the external hard drive plugged in, it messes with the restart/shutdown. The mac will act like it's powering down and go to the blank white screen but will never turn off and shows the little gray lines that go in that circular motion at the bottom of the screen. If I disconnect the USB from the Mac then it completes its power down. I've tried the suggestions of repairing disks or disk permissions, as well as resetting the PRAM, which have worked sometimes but the the problem reoccurs. I've also tried ejecting the external hard drive before shutting down on the Mac but I'll either get an error message or nothing happens and then the above shutdown issue occurs.

 

Why does this happen and what can I do so that I can always have the external plugged in and not have to manually unplug it so the Mac can shutdown?
