I have bought an external 3tb hard drive a while back and have decided that my computer needs more space. So i have put it inside my computer bay and I do not know how to format it to where the computer will read it as 3tb hard drive. My mobo is ASrock z77 extreem4 LGA 1155 Intel with an intel i7 3770k cpu. Help is much appreciated.

the missing 300GB is formatting overhead... no way around it. If you look at your boot drive you will see a similar loss from posted capacity and formatted space.
