    Hi,

    I've installed the original 320GB hd in the optibay and I can't unmount it in disk utility. I'm trying to delete the OS that was original installed on it and is now on my SSD. Any suggestions?

    Not sure if you've solved this yet or not. I had the same problem. The trick is to unmount the drive before going into disk utility.
