I just went out and bought a Lacie 160GB external HD (firewire 400). My intent was to have a drive that I could boot from in the event of any troubles, and also use as a data/backup drive. The catch is I have a PC, and I wanted to be able to transfer data to and from the PC as well. My understanding is that the drive must be formatted to FAT32 to be recognized be both mac and pc, but when I try to install OS X on a fat32 partition, it won't recognize it, and disk utility won't let me format one partition in FAT and the other in HFS. Is there a way to make a bootable partition and another partition that will play with Windows? I want to have my cake and eat it too, please help!!
