do you know if the DVD Burners are still Lite-on Rebadges? if so what models?
All of the recent Sony drive models are based on LiteOn. The last Sony DVD burner to be based on something other than LiteOn technology was its 12x burner released a year ago. As for the model, this will vary depending on when the drive is manufactured. They will be D22A, D23A, D26A, or Q28A. The newer ones should be 26A or 28A. As for the laptop Vaios, they should be either D56A or Q58A, both of which are also LiteOn.
