I have the 13" 250gb MBP late 2010. This hard drive is way too small for me as I have more than 70gb of music alone, and then all my videos, movies, hi-res photos etc on top of that. My music collection is always growing and I have 160gb iPod classic, so I am looking to expand my hard drive. Is it possible to replace the internal HD without voiding the warranty? Can apple do an upgrade like that? I can't find anything on the website. I have a warranty until summer 2013 so I definitely don't want to void my warranty. If it's not possible to do that, maybe I could achieve more HD space by using an external hard drive to store my music on. It would need to be a portable hard drive. And then I would worry about losing all of my music should that hard drive fail. Will I need to buy ANOTHER hard drive to back up that one? I currently have an Ext. hard drive I use to back up with Time Machine. Could I back up both the external hard drive and my MBP internal drive on that one disk? I have more questions about using a tv as a display for mbp, but I'll take that to another thread. Thanks guys!
