How do you format an external hard drive to FAT32 using Windows XP?
Drives under 32 GB can be formatted as FAT32 using the Disk
Management tool (enter compmgmt.msc into the Run prompt and select
"Disk Management from the list when the program pops up). For
drives over 32 GB, you will have to use a third-party tool, such as
GPartEd, since Windows XP does not allow you to create a FAT32 file
system over 32 GB.
