DVD Drive not reading CD's

Hi Everyone,

I have noticed that my DVD Drive is unable to read any of my CD's but all my DVD's are read perfectly by the drive. I have enabled AHCI and installed Intel Rapid Storage drivers post that. What seems to be the problem? Is it because of AHCI? Are there anyone who faces the same thing after enabling AHCI?

I cant deny the fact that my read write and boot performance have improved a lot after enabling AHCI. Valuable suggestions and feedback really appreciated.

Regards

Thanks for the prompt reply electrotune1200. Yes, I have Virtual Clone installed.

"Have you deleted any of you upper or lower filters? " => Didnt get you mate? Could you be specific please.

Nero Lite Essentials is my burning software. I will install ImgBurn and check the filter order, will post a scrnshot as well.

It would be helpful if you can give me an idea about this Upper and Lower filters. What are they meant for? How is related to the reading of a CD ROM?

electrotune => Is it safe to delete the filters from the registry?

Thanks for your replies guys

Ok will post the screenshot. In the mean time could you please explain the relevance of these filters for reading a CD Media.
