I have installed a Toshiba DT01ACA300 3.0TB HDD on my Windows 7 Pro 64 Bit, AMD Phenom II X6 1090 T 6 Core processor, 16GB memory. It displays the HDD as 1.0GB. while I have a WD HDD, which is 1.5GB and it is displayed correctly. Have I missed something? I figured the process should be prttey straight forward but evidently not.
