Here is what happened. I was using my computer, browsing the internet. I had my cell phone sitting on the side of my computer below the keyboard, apparently right over the hard drive. My phone rang, I picked it up, and set it back down once I was finished. Apparently, my gentle set down of the phone was JUST RIGHT (and the planets were aligned) and I damaged the hard drive. The computer froze. I did a hard shutdown. It booted to the white screen, and I heard some icky hard drive clicking. *****. Nothing. Sat for 2 1/2 minutes. Continuous clicking. No booting from DVD. No nothing. Did a PRAM reset. Now I see a flashing folder with a ? mark. I am assuming this means hard drive replacement? If so, Could I just run down to Fry's and grab a new WD 2.5" or something? Looking for clarification.
