This will give you instructions on how to get your DVD player to work in an external enclosure: http://macenstein.com/default/2011/07/ho...

My understanding is that SSD in the optibay for 2011 MBPs will only work on the late-2011 13" model (not the 15" or 17"). I can confirm that it works in my late-2011 13" MBP. I have a Samsung EVO 500GB in my optibay (HGST 1TB in the hard drive bay) with no problems at all: negotiated link speed of 6Gbits for both drives and not beach balls or other slowdowns.

This step was also unnecessary. You can do the whole operation while leaving the subwoofer cable in place.

This step is unnecessary, as is step 8. You can get the SuperDrive out and put the caddy in without pulling the cable out.

My understanding is that SSDs will work (at 6Gbps) in the optical bay of late-2011 13" MBP models but not in late-2011 15" or 17" models and not in earlier 13" models. Are those of you reporting problems installing on late-2011 13" models (MD313LL/A [2.4Ghz] or MD314LL/A [2.8 GHz])?
