I recently had to update the bios of my DVD burner DVD-RW Drive model number Lite-On DVDRW SHW-1635S so it can recognize additional media. According to the bios firmware update software applied everything wen’t right and I got a message Firmware update was sucessful please reboot your system. However When I rebooted my system the DVD doesn’t work to read or Write any CD or DVD in normal booting but does work in safe mode in Windows XP SP2 applied. I tried using a restore point to an earlier date before the update of the bios and that didn’t work either. I tried to reverse the bios update to the prior bios but that can not be done. Is there anything that can be done besides formating the drive. Please Help, the update used was the lite-on YSOV to YSOW.
