Xbox 360 owners have claimed that the console's optical disc drive cannot withstand even small vibrations. They said this causes game discs to spin out of control and become scratched even under normal playing conditions, rendering them unplayable.
Microsoft said class certification was improper because just 0.4 percent of Xbox owners reported disc scratches, and that misuse was the cause.
In 2012, U.S. District Judge Ricardo Martinez in Seattle dismissed the class action claims, ruling there were not enough complaints to justify a class action. But a federal appeals court reversed, saying it could go forward.
