I really don't know what to say.It was making this god awful high pitched noise whenever I turned on the isight camera in imovie. Figured it was a small problem and called apple care. They spent over an hour with me with no success. They kept saying they have never heard of this before and it should not be making the noise. They finally determined it was a hard drive issue and said I was to said this one back in the box they send and they would send me a new one...just wow. I thought thi was such a small issue.
