dsi error when loading games on wii from USB hard drive Answered

Hi,
I am also having lots of problems with the screen getting lots of strange symbols when scrolling through the games and then it crashes with a dsi error and other comments. I have to turn the wii off at the mains. this is happening with probably 80% of the games that I put on the hard drive. Once I delete the game off (that was downloaded last that caused the issue), all is ok with the games that are on and ok. Can you help?? Daz
