    I installed a Crucial M4 SSD into my late model 2011 macbook pro. I originally had intended on it living in the optical drive bay until I read the numerous threads about how the SSD can't be used to it's full potential in that place. So, I swapped the HDD into the optical drive bay and placed the SSD in the old HDD bay. When I booted this am, it booted fast into the SSD, but now I can't see the HDD in disk utility or on an 'option' startup. Any help appreciated! Hope Kappy is out there today!
    I hear the fans running, so I'm assuming it's trying to spin the HDD perhaps?

    Did you do SMC reset After installing the SSD ?.

    The SMC reset procedure is Left-Shift, Control, Option then Power button. Do a hard power off (hold power for 5 sec). Then wait a couple of seconds, power on.

    You might want to check that the HDD in the OptiBay is well secured since the tiny ribbon cable could well snap out depending how you handled your laptop. I would do the following:
    1) Use aluminum foil and shield the "old HDD " cable. It helps signal integrity especially when mentioned that the cable quality might be poor. I heard it works well for some.
    2) Use small strips of electrical tape and secure the connection points of the OptiBay. Both on motherboard side and disk side. Like I said real thin ribbon cables there.

    Also, did you update the firmware of the Crucial before you install ?. This is really mandatory, since the latest firmware will cure most weaknesses before.

    My case, a few days research and preparation makes my Ocz Vertex 3 install on the first-gen Unibody MBP a breeze. No problems with 3GBits negotiated link and CDdrive works perfectly. Also trim was enabled with Trim Enabler 2. My model has had lots of problems with users before, but all those solved if the right percedures were followed. That I did and it flies!. Now with ML, its a joy to use ... Good luck.

    ya know....

    Sometimes even the most confident geek doesn't do the simplest things. Thanks for recommending me re-checking the cables. Sure enough, the connector had come loose. So, obviously it wasn't seeing it! :rolleyes:
    Anyway - I have 000F firmware and trim enabled for the SSD. Is there anything else in your recommendation that I should do to have it operate optimally?
    I cloned my HD (with the exception of music/photos/movies) to the SSD, so the OS is on it, along with apps, settings, user, ect.
    Thanks again for your help! Really appreciate it! :)
