External harddrive on Atv tips please

Ive installed Atv flash and ran all the additional downloads
ran the smart installer and followed all the instructions
to the book

But I cannot figure out how to get the apple tv to read my harddrive

Ive tried for the past 3 days with no luck at all

I tried reformatting my harddrive to fat32 and that didnt work

I tried everything

I have a brand new western digital 1tb harddrive
And work mostly on my black 2007 model macbook
but also have a windows computer running windows xp

Can anybody point me in the right direction please

Im pulling my hair out trying to get it to work

any help on this will be greatly apreciated

Thanks in advance
