I have a 1tb external hard drive that I need to format to Fat 32, but when I try to it will only format to exfat or ntfs on a Vista computer. I have also tried to format it using a win xp comp, but it will only do ntfs. I tried using the cmd.exe on the vista comp but it pops up with "application not found". recently had problems with windows vista guardian, but thought i had fixed them. please help!
