My Liteon SOHW-1673S (patched to 1693 with codeguys’ firmware KC4B) is not reading any discs. I noticed this just this evening.
When I insert a disc (CD/DVD) the read light just flashes once and goes off. The drive reads as empty in Explorer, and Nero reports that there is no disc in the drive.
The drive is detected perfectly in My COmputer and by Nero and all other apps, and Hardware Manager says it is working fine. Nero Infotool also detects the drive perfectly and lists all its features normally.
The drive just will not read any discs at all.
OS is WinXP SP2 with all patches.
Regularly scanned for viruses and spyware.
