The fat32 bit is getting you. There is a 4gig limit on file sizes in FAT32. NTFS has a much larger limit.
Your computer is probably formatted NTFS unless you upgraded it from win98. A lot of portable drives come formatted FAT32.
You can convert the drive to use NTFS by using the convert command. Or just reformatting it (if your data does not matter this is the way I usually go). If you need it to plug into something that only understands FAT32 you may be better off creating a couple of partitions on the drive. One FAT32 and one NTFS. Even then some devices are picky. But if you are just going to use it for XP computers then it is no big deal.
