Having just received my macbook pro I put in a CD to copy some media from it and I was shocked to hear my machine make such a horrible noise. Forgive me for asking, (this is my first slot loading drive) but is it normal for it to sound so horrible? To fully describe the sound is almost impossible. It sounds like it was eating the disk and trying to regurgitate it, both during the process of putting the disk in, and ejecting it. I figured this might also be one disk, but every disk I have put in so far has done the same thing. The discs function fine, but the noise scares me. Any help? -Damien.
