Hi, i'm going to be getting a LaCie 500GB external for my 20" Alu iMac, and I was reading about formatting and i'm unsure on how I should format it. I'm going to be getting Windows XP to use with Bootcamp, so i'll be switching back and forth between that and Leopard. I was reading if you are going to be switching back and forth between PC and Mac, to use FAT32. Should I do this in my case? Will I be able to partition some of the external drive for Windows and the rest for Leopard? I'm unsure of this, so hopefully someone might now.
