I've tried 3 different USB hdds and I get the exact same result, tried waninkoko's 1.5, usbloader gx from the google code site, and now the usbloader gx channel. I can format the drive using WBFS Manager in windows, and add games in windows without problem. When I plug the drive in to the wii and load up a usb loader, it sas "WBFS partition not found, please format" then it takes me to a screen showing 4 partitions when my drive only has 1 actual partition on it. The usbloader gx from the google code site and waninkoko's loader both tell me the 4 partitions are not formattable. The usbloader gx channel allows me to actually select one of the 4 shown partitions and format it, but once its down it black screens with a code dump. I had waninkokos cIOS 36 rev 10 installed as ios249, and then installed cIOS38 rev 13 (non b) as ios249 (guessing it overwrote). This is really the only thing I can think of that might be causing a problem. Do i need to have both of these to run correctly? how can i install both of these independent of each other, if that is needed? Any other ideas as to what might be going on?
