Anyway I went to pickup the ST3500641AS drive from BestBuy and they tried give me the Ultra ATA version so I returned it for a credit. I ordered another ST3500641AS drive and went to a different Best Buy and got the ST3500630AS with the AAK firmware made in China. I still think it is a good deal for $99.00 and I really didnt expect to get the perpendicular type drive at this price.
