I have bought a nice PCG-GRT916Z Sony notebook with a burner Sony DW-U54A… As I got a lot of trouble when burning with a lot of media brands (TDK-R, TDK+R, TDK-RW, Opti 8X,…) I would like to know if someone can tell me if there is a new firmware available from Sony for this drive or if I can use a Firmware from another brand ??? or can I use the firmware from the DW-U56A ??? or is it may be defective !!
Thank’s for your help & Have a nice day.
