My main HDD with Wii games is a 500GB 100% WBFS partition, my second HDD is 320GB WBFS/FAT32, I use the WBFS partition for installing WiiWare ISO forwarders used with CFG, and the FAT32 holds my Wiiware and emulator roms. I do have a third 1TB NTFS plugged in to my computer that I have used with my Wii to watch movies, but since WiiMC was was released I just watch the movies from SMB shares.
