I've run through this tutorial twice. First time I switched our the HDD for a 1tb, and the DVD drive for an SSD. The HDD works but the machine didn't find the SSD. I then swapped them - it now finds the SSD but not in the HDD which is now in what used to be the optical drive slot.
Do I need to buy a new cable for the optical drive? As it appears that's what it's not reading, or is there something I've missed?
