You need to have ATA Hi-cap loaded onto your boot drive to see disks larger than 120. http://www.speedtools.com/ATA6.shtml I boot off a 120 hard drive and use the secondary 350 for pictures and music and documents. I did boot off of the 350 partitioned until the extension didn't load and changed my whole boot location. I tried putting Applications on another disk and some don't work real well. If I remember correctly its the firmware not the system that determines the size of the drive it can read.
