Hey guys ~ Why is it so hard to find solid information on the macbook air hard drive? I have searched high and low and I get so much conflicting information. I figured I'd ask where people may have done the upgrade themselves or have more info about it. I have a A1237 Production: Jan 15, 2008 - Oct 14, 2008 Factory: China Production Year: 2008 Production Week: 03 (January) Production Number: 2802 Base Storage: 80GB 4200RPM EIDE 1.8" This is all per powerbookmedic. I need to at least make an upgrade to a 120gb drive. The problem I keep reading about is clearance with the thickness being too much. Can anyone give me specific model numbers that are compatible? Thank you!
