Today I wanted to replace one of my HD's. I tried to remove the old hd from the bay but it turns out that I had fastened two of the screws too tightly. In my efforts to unscrew them I've worn out the screws (the 'insides') so now my screwdiver can't grip them properly anymore No matter how much force I use it just keeps skipping. Any ideas what to do? An option would be to get a new hd bay but where to get them? Is this something Apple Care would cover? Many thanks.
