Well this is stuff i do that might help you
NEVER BLOW AIR IN YOUR XBOX!!!!!!!!!!!! Becuase it will cause the dust in your xbox to go all over everything! So then you will have to open your xbox and clean it! And that might not be fun. Well try this first!
Above the disk drive is the plate aka cover. Yes (i hope there is). What i have tried is push down on the cover and you will see it move down some. You will need to hold it and what tell game is loaded. This might work this might not work who knows. But i know it worked some what for me. So it might work for you! Well i hope it does.
If this doesnt work i would say your reading lense are dirty. You might need to get in there and whip it with a damp q-tip. (not to wet though)!
Well thanks tell me if this worked for you.
