Hi I just installed a new Toshiba PH3300U 3TB internal HD to my Gigabyte UEFI Z87N-WIFI Mobo. When I go to format it in the windows disk utility it will only Format 2TB of the disk. I googled this. Win 7 + and UEFI Bios with 8 series SATA drivers should recognize this as a 3TB disk. Anything I am doing wrong or does my mobo for some reason just doesn't support 3 TB? I updated the Bios to F5 (lastest) still no go. Any help will be great. Thanks!
