Hello, I searched the MacRumors forum and the Apple Support forums but I still couldn't find the answer to my question. I've had my 17" MBP for a week now, when I first got the notebook, the optical drive never made a sound during boot up. But after a week the optical drive makes a noice (I know this is normal), but I want to know WHY NOW? Why didn't it make the noise when I first received the MBP? I don't think anything is wrong with my optical drive because it works and I searched the forums saying every MBP does this. I even tried to reset the optical drive. But why does it make the noise after a week of owning it? I just want a straight answer. Thanks in advance.
