Hey, Has anyone tried using the WiiKey DVD DumpTool to format a SD card to backup the Wii DVD's? I followed the ReadMe & went into a DOS prompt, ran dumptool.bat & entered the drive letter (E), when prompted, of my SD Card on the PC to format it. I get "Error opening device!". I have tried this on 2 different laptops with 2 different SD Cards. Same result. Any help is appreciated!
