Windows 7 won't recognise my 3TB Tags: Memory Windows 7 Last response: December 23, 2012 9:47 AM in Memory Share pirateslug December 23, 2012 4:01:55 AM I have done as previous stated, change ide back to achi via registry editor. I can only see my vertex ssd 120gb and not my 3TB hdd. I can't see it in device manager or disk manager and it doesn't show up in the BIOS either although it did show up when I had to choose which partion I wanted to install Windows 7 on. Also I have another question which has nothing to do with this: Do I leave External sata 6gb/s controller mode disabled or enabled with achi? Thanks in advance.
