How to format it to FAT32?

Hello.Recently I got the manual from my media player (aka HDD).I want to connect it to my TV but the manual says it only supports FAT32 file systems on the TV. But then, I can't format it to FAT32.
I can't partition it to FAT32 either.I am using Windows Vista Business. I can use Windows 7, and possibly Windows XP, to format the drive again.I am having 3 partitions on the drive. One for media files (which I want to format to FAT32), one for extra files (which I want to keep NTFS) and one for Wii games (WBFS).How can I format the first partition to FAT32 and why can't I select it when trying to format?No firmware upgrade is no option as it still needs the player in FAT32.

Thanks for the program hYpNoS. Got it to format the 300 GB partition to FAT32.
