I bought a 3.5" internal SSD drive for a new Mac Pro. Connected it via an external USB docking station, where it mounted fine. When I remove it from the docking station and add in to an internal hard drive bay in the mac pro it does not show up in disk utility. As soon as i put it back in the USB docking bay it re-appears. How can I get it to show up when IN the mac pro??? Please help!
