Thats a very unusual problem. I have had this drive in the past and apart from being noisy as all lite-on's seem to be it has given great service. the only suggestion i can make is that you update the firmware by going onto Lite on's site and download the latest revision of firmware. if still the same then can only assume the drive or your burning software is corrupt.

make sure that the cd/dvd rom is getting enough power test all leads that are attached to the dvd including electrical extensions and make sure they have a secure connection or just replace them there might be bad/faulty or your drivers may have been corrupted or you might have a virus run your antivrus program you might have to physically unplug the leads for this cd/dvd rw then plug them back in or you might have to uninstall then reinstall your DVD/CD or uninstall the driver then reinstall for this device click start control panel administrive tools computer management device manager scroll down cd dvd rom drives if you see a yellow question mark? right click you will have options to update driver,roll back driver,or select properties general troubleshoot, select driver click to reinstall drivers click update driver or uninstall then reinstall Click start control panel administrive tools,computer management,device manager scroll down cd-dvd rom drives you might see a yellow question mark ? right click you will have options to update driver,roll back driver,or select properties general troubleshoot, select driver click to reinstall drivers click update driver or uninstall then reinstall if this does not fix the problem it might be a registry problem if you cant see your disk drive in windows explorer Close all open programs

I was having a problem getting my dvd (Lite-On LH-20A1P) to read my cds. I found a very simple solution that worked for me. I hope the following procedure works for others.

I have windows xp (I believe this solution may work for other window versions)

Go to "My Computer" on desktop (or in Start) and right click on it.

Click "Properties"
On the tabs at the top, click on "Hardware"
Click on "Device Manager"
Click the plus sign beside "DVD/CD ROM drives"
Double-click on Lite-On
On the tabs at the top, click on "Properties"
At the bottom, there is a box that is most likely checked that reads...
"Enabled digital CD audio for this CD-Rom device"

Uncheck it.

Do the same for all DVD/CD Rom devices you may have.

This simple solution worked for me. Now both my DVD and CD Roms are reading all of my cds.

I would suggest trying this simple step first before downloading any drivers or buying any 'Driver Update' programs - which may cause you even more problems than you are already having.

Try downloading eusing registry cleaner.
Its free and once it's done, restart your computer and put the drive back in.

Check for loose contact, dry solder at the power connector end, try cleaning the lens, most of the times the rubber belt that is used to drive the tray gets loosened due to time factor and usage
