Uhh... I don't mean to be a dick when I say this but, I bite the edges of cd's when I'm angry and they still work, So I tested it, A big line through the middle and you say ' it broke '? Hmm.. A CD doesn't break until it's split into two or somehow, so it should work. It's just a scratch don't worry. Also how do you know it doesn't work when you didn't put the cd in?
