So the other day my Wii got pulled off a desk onto the floor because of an overzealous friend playing SSBB with a wired gamecube controller. The disc has a big radial scratch on it about 1/3 of an inch from the outer edge and and I frequently get Disk Read Errors when playing SSBB now. I tried playing Wii Sports today to ensure that my wii was OK and it was just the disc and that went fine with no read errors. My friend is replacing my SSBB disc, but I want to make sure the Wii itself is not broken before letting him off the hook. Anyone have any advice on how to test the Wii out to ensure its in full operating order? I plan on trying out the game on another friend's Wii tomorrow to see if i get the same read errors. I figure if the read errors persist on a different Wii then the disc is the culprit. Thanks for the help.
