I have 500GB LAcie USB Hadrive, which i currently have partitioned into 200GB for Timemachine, and 300GB which i use to drag and drop files/folders directly from finder. Is there anyway for me to partition the 300GB so i can use this HD to backup some of my bootcamp files. If i can, what format do i partition in. Can i just partition the 300GB now or do i need to reformat the HD and add 3 partitions from the start. Also is xp good at picking up and syncing HDs, esp for drag and drop stuff. Im so used to mac, i assume xp will make my life difficult.
