A simple bump? A jump near the console? Subwoofer? ZOMFG, I have a cramped room, hence I bumped into my PC's desk countless times, but I never scratched a CD or DVD this way, not even with the old LG CD-R/RW, noisy and vibrating more than a helicopter.
OT, about vibrations, two days ago, after having always been mostly on 737's and MD80's, I flew for the first time on a Bombardier CRJ-900 less than 3 years old and... I never thought a jet airplane could vibrate so much, my mom was so scared she almost pierced the seat with her nails
, I joked all the time about mechanics getting left-over nuts and bolts after maintenance and she got even more scared, as if my sister telling her major airplane disasters often happen in series of three wasn't enough
