Xbox not reading game

I don't know if this will help anyone, but I have tried a variety of things that occasionally have worked. Eject disk and pop it back in and then restart 360. Sometimes may require doing this a couple of times. If that doesn't work, try unplugging that thing in back with the orange light and replug it. Or simply, as it worked for my brother, just turn the 360 off and unplug the orange light thingy and don't play again until maybe a week or month, etc. He unplugged it for about 3 weeks and then it worked perfectly again. Sometimes the 360 just needs a little break. Even though this may be impossible for most to leave it alone for even a day, but its either you or your 360. make it live again!
