I just built a new computer. I put a 128gb SSD and a 1TB HDD in it. I put Windows 7 Home Premium on the SSD, and now I want to put all of my files and games on the HDD. I tried to activate the HDD by creating a new simple volume, but it will not allow me to do this. The options create a new simple volume on the unallocated disc is grey and not usable. Any ideas as to what the problem could be?
