No recognition of CD/Dvd drive

Have rebooted and wiped memory. Started over and still have prblem, sometimes it will recognize the cd drive when there is something with a USB in the USB port. Computer states that everything is functioning fine, exept it can not find the CD drive when it is told to. It registers the drive in the Computer Information, don't know what I did. Can anyone help me?

I had the same problem with my PC with a new optical drive and all I had to do with replace the cabling and that fixed my problem. No issues since then. I would suggest to try this if none others have worked.

CD and DVD drives use lasers to read the disc. If the door pops open, Device Manager says everything is fine, and the drive spins, but it can't see a disc sometimes. Either the disc is dirty, the lens is dirty, or the laser is failing. The lasers do burn out a lot. They last about as long as light bulbs.

    Nobody does replace the lasers. As if you could, it would cost far more than the drive itself. If you don't want to replace the whole drive and you get one of those slimline DVD/CD drive which are really small that plugs into an USB port.

You can try to delete Upper and Lower Filters in the Registry by going to the registry editor (Sart>Run>Type regedit)

After deleting those and you restart your computer, it should work and detect those by now since system recognizes device, if it doesn't either, there is a problem with your OS, you may try repair or reinstall of OS.

Thanks.

    You will find that in the registry editor...



    In Windows Vista OS (Operating System) you just have to type regedit on the Search Box that appears after you click on Start (The Windows Logo in Vista -- Lower Left Side of the Screen)



    After you have the registry editor window... that's where you'll search for the lower and upper filters. Pleasebe careful in deleting or altering files in the registry as this will cause your computer to go haywire if some important system files gets deleted.



    Thanks.

My drive will not burn dvd-r anymore but it used to, it burns cd-r and reads discs no problem, but now when i try to burn the disc spins but makes a strange knocking noise.


sometime it has more to do with the driver software than it does with the unit itself.
Try uninstalling the writer software, restart the computer, reinstall the software, restart the computer, and attempt burn again. Software occaisionally gets confused and needs to be "rebooted" from time to time. Hope this helps.

CD / DVD player not listed as device on Windows Explorer


Try physically removing the player and fire up the laptop. Power down the laptop, replace the player and power back up. If that doesn't help, see if BIOS recognizes it.
If that doesn't work, get back to me.
