hey guys, well i just got back from vacation and I tried turning on my macbook, but it wouldn't startup. it made a clicking noise and all that appeared was a white screen and a folder with a flashing question mark inside it. I then put in the apple disk it came with and went to 'disk utility,' but it wasn't able to find my hard drive. Is there any way of retrieving the data on my hard drive, or even better, fixing my macbook? luckily, for me, my warranty just expired while I was on vacation, and I'm not able to talk to apple customer service without paying 50 bucks. any help would be much appreciated. thanks.
