That's the drive in the 17", I thought the drive for the 15" had to be smaller even, so they are different which is why only the 17" 7200rpms are shipping ????
They are both 2.5" drives and probably the same exact drive. I'm in the same boat and its really ticking me off. I went through the same exact thing with the GeForce 6800 Ultra on a G5 2x2.5. Of course there was actually a shortage of that card. I don't know of any shortage of 2.5" SATA 160gb 7200rpm Seagate drives.
