MacBookPro8,3 late 2011 17", Lion OS X (pre-loaded; no disk) 10.7.5 The original issue was the hard drive (750 GB) has a "S.M.A.R.T. Status: Failing" so I began looking into upgrading to an SSD. Now, when I place a CD in, it does not show up in Finder. I hear it load and I am able to eject it with the keyboard button but it just doesn't show in Finder. FWIW, the MBP has been dropped a few times resulting in a barely visible indentation on the bottom left corner below my left arm as I type this as well as a slight gap in the seem, which separates the removable base from the unit. Also, the Power Adapter cord is broken right next to the main square piece. I've taped it's so close to the square that it just keeps coming undone. That said, how worth it would it be to upgrade my late 2011 17" or would you just get a new notebook? Thanks!
