I just put in the Scorpio Black 7200 and could not stand the vibration/hum of the drive. I went from a perfectly quiet macbook to this constant hum, no noise, just could feel it. Anyway, thought I would try the 500gb Hitachi TravelStar 5K500. Confirmed that it fits the aluminum macbook. I was able to fit it in and close the battery lid. I am wiping out the Scorpio so that I can return it, but thought I would share that this drive does fit. I will take some pictures when I install it.
