Um... so your drive is formatted as WBFS or FAT32? If it's WBFS, use this tool: Wii Game Manager v126.96.36.199 [wiiGM] (download torrent) - TPB to transfer ISO's to your WBFS partition. If it's FAT32, use the link I gave, and using the software, convert .iso to .wbfs files. then make a folder called "WBFS" on your drive, and put the .wbfs file there. Then use USB Loader CFG, USB Loader GX, or WiiFlow to make sure it works. If CFG, doesn't work, try the other two.
