Recently bought hp 14n someting or other with xp media ed. came with hp burner. had best buy install a sony in open bay. buned happily for a week or so and decided to upgrade firmware in sony. did not work. lost both the sony drive and the hp drive. do you think best buy can fix this or will drives have to be sent away?
thanks,
Mark.
