I've just threw a Samsung 830 512gb ssd and put the 500gb hard drive in the optical bay. I figured out how to clone my old hard drive to the new ssd and everything boots up fine and I even updated to Mountain Lion. So I really don't have anything on the macbook except for the OS, I would like to grab all the music, pictures and videos from my PC and put them on the hard drive in my macbook pro, I just don't really know how to go about this. I would appreciate if someone could guide me with how to do this. Am I supposed to have the OS on both the hard drive and ssd? Do I erase everything on the hard drive before I try migrating from my pc? I plan on just moving my files with a memory card, I don't have that much data so that's not a problem. I just want to know where and how I am gonna put my data onto the hard drive in my macbook. I appreciate all the help.
