I have an external WD usb 3.0 drive I want to move inside my 2008 Mac Pro. The drive is 3 tb, and my Mac should see this as 3tb. When I take the drive out of the enclosure, and remove the usb 3 interface card, the and connect it to my Mac through a usb drive dock, it only show 800 gb. I tried to format the drive through Windows first to get the 3tb, but alas, only shows 2tb. Can I simply put the drive in my Mac and format is as usual to get the full 3tb?
