So I followed the 3.1-4.1 Softmod for ANY Wii and then added USB Loader GX and cIOScorp 3.6 for DVDR loading. I formatted an SD card WBFS and installed a game on it, put it in my Wii with a USB card reader and it booted the game fine.

Fast forward a month or so and I got my hands on an 80GB hard drive and I wanted to try loading from it, and it did not work. I figured it wasn't compatible so I tried an SD card and that didn't work either. Decided to use my original SD card that worked a month ago and it still wouldn't.

If I put the card in formatted with nothing on it I get the error, if I put something on it I get the error. The only way I've found to avoid the error is to put it in formatted FAT32, USB Loader GX then tells me to format it which I do, then I load a game from the DVD drive onto the SD card, the game will boot fine but once I exit out and try to use USB Loader GX again it gives me the same error.
