Partition your not easy drive so that you have your own FAT divider for system recovery next to XP so if you need to reformat, you can reformat minus keeping spy/adware and viruses around. NTFS format ofcourse. Other than that.. I don't know what else to let somebody know ya.
Normal use, use all the space, format ntfs
