I was testing the reader of my Wii U, I decided to put in discs since I hadn't used this one for a while and I didn't know if it read them, out of curiosity I decided to insert a CD-R disc, a disc totally unrecognizable by the console, and to top it off scratched, it threw me several times the "Invalid Disc" and it didn't want to eject it, when I tried to read it again, my surprise is that now it says "Wii U Cleaning Disc", I know that there is a disc to clean the official Nintendo lens, but it makes me laugh and also some intrigue to see that a totally random disc that is not at all functional and damaged the console recognizes it as that official Disc of the console, even throwing the cover of the disc that literally is the same as the official one and the shape of the real disc, does anyone know why it happens? Haha, because I've tried several times and sometimes it says again "Invalid Disc" but a few times it throws up that cleaning disc again, and it happens very frequently, I don't know if it only happens with that disc since I don't have others to test.
why havent you modded it yet?
