I don't see why people mess partitioning HDD's,
I have a 500GB WD Elements formatted to FAT32,
WBFS folder for all the wii games using CFG USB Loader
MOVIES folder for xvids played via WiiMC
TriiForce for Wiiware&VC Games
The only slight down side is i can't have single movie files over 4GB
But drive is one format, can be read by PC, drag & Drop games
Back to the matter at hand, does it matter as the which partition is the primary one?
