I just bought my 13" MBP and I'm trying to put in my Seagate 7200.4 hard drive. As near as I can tell, I just unscrew the bottom part and take out the old one and put the new one in. Problem is, there is one screw on the bottom right-hand corner of the machine that absolutely refuses to move. I am using the correct size screwdriver and all the other ones came out fine, it's just this one that seems intent on thwarting my efforts. Since Apple says that they won't put in the drive themselves, I assume that taking it to the genius bar isn't an option. Has anyone done this yet with their 13" MBP?
