Hi ppl, Please help me out on this one. As I was taking out my hard disk from my macbook (which I've done a few times uneventfully), during this last time, the screw caught on something. Long story short, this piece of rubber came out: There is another piece in there, still in place. I think they hold the hdd in place, and reduce shock when I move the macbook around. So, with this missing, I'm not sure how much damage it'll do. Problem is, I don't know how to put it back. Question. Can the genius ppl fix it? Have I voided warranty by exchanging hdd? An unrelated question, have I voided warranty by using 3rd party memory?
