I just got my MBP 17" and its wonderful. Just to answer future questions I have the glossy screen and love it. Hard drive- 7200 rpm (unknown manufacturer) Okay so the problem is that I lifted my computer up and i heard a screeching sound where the hard drive is. Like the disk was spinning against another metal object. This only happens when i lift the computer slightly fast or am going up the stairs. I know this isn't normal. Does anyone else's computer do this? Should I return my computer?
