Hi, i guess the option to format in Fat32 is not available in Vista because
it wont allow partitions above 32Gb to be formatted.
That doe`snt mean you cant its just the O/S restriction.
Im guessing your drive must be larger than 32Gb and its an external Hard
disk.
You need a third party formatting utility and i think this one will do.
GParted livecd,........... do a search and you will find it.
By using a boot cd you wont need to worry about software incompatibilities
in Vista.
Just be sure you format the right Drive !!!!!
