I just finished this build and loaded Windows 10. I have a SSD that Windows is loaded on. Since I didn't have enough sata data cables I used one for the SSD and the other for the optical drive to get some drivers loaded. Once I didn't need the optical drive any longer I switched the data cable to the 2 Tb HDD. I also used a different sata connector on the Motherboard. The disk shows up in the disk manager but as allocated after I initialized it. The drive is empty.
