@peterbull - Peter, I'm confused ?? You swapped out the optical drive for your SSD so you shouldn't have any problems access your old HD unless you disconnected its cables from the logic board by mistake. I would double check the connections. You may want to run Disk Utility to see if it shows the HD if it does then your issue is just a matter of making the drive visible on the desktop. Go to the Finder's preferences and check Hard Disks.
