I recently installed an SSD and loaded a fresh copy of windows 10 on my computer. I have two other internal HDD"s in my computer as well. I have the SSD and my first HDD plugged into the two 6GB/s SATA port's on my motherboard. I then have my DVD drive and my second HDD plugged into two 3GB/s ports. When I boot Windows from my SSD, the first HDD show's up, but the second one doesn't. When I boot the Windows copy on my first HDD, the second one does show up. Any idea's?
