So I didn't have the latch on the back of my MBP and one time I grabbed it from there. My fingers must have pressed on to it too hard that it made a grinding sound. Next thing you know, the screen is gray with a question mark. I took it to a local Apple Repair Store and they told me what the problem was. They said the hard disk failed and I would have to replace it. They sell harddrives there but it's too pricey. I was hoping you guys can help me find a place (store or online) to buy a cheap harddrive. I only know of newegg.com but I want to check other places just in case I can find a better deal. Also, at certain angles, my MBP's touchpad gets like jammed and I won't be able to click or anything. I also told the repair guy at the store about this and he told me it might be a little loose. He said I can unscrew it and tighten it or something. How hard would this be to fix? I've never done anything like this. Thanks in advance. I'm hoping to get this fixed because I hate using any laptop that isn't a Mac. I especially miss Mac OSX.
