You may also like to update your firmware on that drive as YS0N is early and the latest which matches more media and also fixes DVD-r leadin problems is YS0Z http://www.liteonit.eu/eu/DOWNLOADS/ODD/SH...re/DR16YS0Z.zip
When you update make sure there is no media in drive and that the tray is closed and do not stop once it starts or switch off PC until it says completed and it asks to reboot, (reboot once finished even if it does not ask)
