    Hi Folks,

    I was trying to install a second optical drive in the free slot. I followed the instructions provided by apple and put everything back together. After booting up neither the new drive nor the superdrive (that came with the Mac) were recognised. I checked Disk Utility etc.

    I removed the new drive and tried again, no luck.

    I connected the superdrive (by itself) to the end connectors of both cables, no luck.

    I don't know if I've damaged something (I don't think so) or if I'm missing something or what?

    Any help would be greatly appreciated!

    Come to mind here. First you have bent the pins on the board, (I hope not) or you are not seating the power connection properly?

    Thanks for your response.

    Which pins do you mean?

    I tried a few times so I think the power connection is fine, I've plugged in a few drives in my time.

    Just looked back over the guide, found something weird about reattaching:

    Attach the power and ribbon cables to the back of the drive(s).
    Important: Attach the connector on the end of the optical drive ribbon cable and the
    connector in the middle of the optical drive power cable to the top drive. If there is a second
    drive in the carrier, attach the remaining optical drive ribbon and power connectors to the
    bottom drive​

    I'm at work right now, but I may not have tried top of ribbon cable and middle of power cable, will check when I get in..

    The cables were connected properly, but I think I've got the real problem: the ribbon cable has a very small incision.. No idea how it happened.

    I can't even see where the ribbon cable goes after leaving the optical drives bay.. Am I out of luck here or any ideas?

    Check jumper settings of drives. If both are set to master/slave they won't work. One must be master and second one slave (or set them to cable select).
    IDE cable goes to connector located under front fan assembly.

    Also be aware the power cable connectors (molex) can be as tight as all get out. You may need a pair of needle nose pliers to get them apart and together again.
