I have setup my wii with usb loader and as a test i tried to rip a game to an 8gb usb pen but it failed and now the usb pen is write protected under any os but can be read just not formatted or files deleted.
Under the wii and the file browser homebrew app i can copy/delete etc so the pen is working but no idea whats going on as its not useable with anything else no, can anyone help?

Thanks
