Check the drives in the Disk Management console. In Windows 8 move the mouse pointer into the bottom left hand corner where the start hint appears, and to a right-click. You should get a menu of options including a link to Disk Management. What does that 320 drive in question look like in there?
It shows Drive D: the 320gb one in question quite normally... 128gb ntfs healthy 170gb unallocated. It was reading my 1TB empty drive wrong until I allocated it I think that's what I need to do right? I can select new simple volume but that sounds like making another drive which I don't want I just want to combine that with the healthy part which has data on it of drive D. Thanks for reading!
