Around 10 days ago I bought a 500 GB external hard drive made by Toshiba from Wal-Mart. The device worked fine for around a week, but today when booting up New Super Mario Bros. U it flashes to a screen that says, "There is a problem with the USB storage device" giving me an error code of 160-0105. What the heck does this error code mean? My system recognizes the USB storage device and has my game save on it, but it wouldn't allow me to copy my save data to my internal memory or allow me to use it while playing games. Does this mean I have to reformat my external hard drive again?
