my dvd went bad

i upgrade my lite-on dvdrw sohw 812s with a new firmware(DR8USOS) it was working ok but the next day it does not read dvd's or burn them, but it reads the cd, i upgrade the dvd because it did not want to burn dvd+r, and i did use good media (verbatim) need help , i just don't want to buy a new dvd burner

 

Try this:
Go into your Device Manager, and find your drive. Right click on it, and choose "Uninstall". After it uninstalls, reboot, and let Windows detect new hardware, and install new a driver for you.
Good luck!
