I can only speak for myself. Before I had a German MBP and now have an American one. Both are mid 2009. The German one had a different hard drive than my current American one. In system profile it said the German one was made by Nvidia but had the same serial as a Seagate(ST......). My American one has a Hitachi HDD in it. Does apple do this for each continent or country? Say USA gets Hitachi ; EU gets Seagate/Nvidia. Or are HDDs randomly chosen for each MBP? Are there any big differences between the hard drives? If it makes any difference both were 2,26 ghz and 160 gb models. Both were brand new.
