I have a premium 360 about 4 months old and made a mistake, I went it to a "mate" for a few nights, it turns out then he lent it to another mate (whom i dont know!!) 
and now when i out in a cd it makes an odd noise but no marks on the disc
so;
1) what do i do about the "mate"?
2) what do i do about the 360, hope m$ accept it or not (under warranty)?
