in BIOS , UEFI Boot is enabled , ACHI Mode is selected , and the 3TB Hard disk (Seagate ST30000DM001) is installed at SATA Port 3.
However, in Windows 7 64-bit, 3TB hard disk is displayed as 746GB, no matter how do I format or set the settings. I use GPT as partition table ( as suggested by Windows , > 2TB should use GPT ).
How can I get back the full 3TB storage ?
p.s. Motherboard is Intel DH55HC and Intel Rapid Storage Technology software shows the disk capacity is 2.862GB .
p.s. Operating System is Windows 7 Ultimate , 64-bit
