Perhaps the recalibration trick every Philips cd-writer has will help , but i'm not sure.
1 - Power down your system
2 - Press the eject button of your philips cd-writer and KEEP PRESSING IT
3 - Power up your system , still pressing the eject button. Do NOT let your operating system start. Press PAUSE to stop the Power On Self Test (POST) or enter your bios/setup.
4 - See all the leds on the writer flash back and forth. You can now let go of the eject button. The cd tray will eject. It is now recalibrated
5 - Let go of eject button and press it once again to put the tray back in the writer
6 - Power down your system
7 - Power up your system
8 - Boot to your operating system in safe mode and check out the reading capabilities of the writer
9 - If correct , reboot in normal mode and check out the reading and writing capabilities of the writer.
