My old hdd (which has data I need) is listed under disk manager as RAW. all of my controllers in device manager say ACHI. The old OS was Vista 64bit, could the problem be from vista to win8? The hdd in question doesnt have an OS on it, its just purely data without a partition but im not sure if there were a different architecture used between the two OS that could be causing this.
Thanks for the response btw
