Simple solution:

Situation
There is a yellow exclamation mark for CD/DVD drives in Device Manager. The device status in the properties of the driver might indicate an error code, for example 32, 37, or 39.

Solution

To solve the issue, you have to edit the Windows Registry:
Click Start, then Run, type REGEDT32 and click OK.
Locate and then remove the following registry values:

HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlCl ***{4D36E965-E325-11CE-BFC1-08002BE10318}LowerFilters

HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlCl ***{4D36E965-E325-11CE-BFC1-08002BE10318}UpperFilters

Close Registry Editor.
Reboot the system for the changes to take effect.

Note: Some programs are unable to detect the CD/DVD drive after these steps. To solve this, simply re-install the program in question, eg: usually your recording software. Also, in few instances the order in which the programs are (re-)installed can make a difference.

And here's another method that will do this automatically for you if you're afraid to edit the registry manually.

Thanks for your prompt response. Since I was afraid to manually edit the registry, I tried the other method you suggested (download file: CDGone.zip). After going through the process and re-starting my laptop, my optical device works perfectly! Thanks again, Mr. Super Moderator!

you're very welcome. glad it worked for you. And I want to thank you for trying the cdgone file. You're the first member that's said you used it and it worked. I had previously examined that file and tested it but I was curious if anyone else had tried it. again thanks for your comment.

Hi everyone.

I have the same problem with my Matshita DVD ram UJ 841 s, but nothing is working. Tried to uninstall and reinstall the driver, but the latter has no effect. I removed the upper and lower filters and uninstal and reinstal the drivers, but no change.

Any ideas on what else I could do? Needless to say I cannot take into any kind of consideration the possibility of restoring the system with the manufacturer's restore CD-Rom. And how could I, anyway, since the drive is not being recognized by the system?

Guys, please help.

Thanks.

Jim

Hi Jim,
ok. let's first test the drive to see if it's working. Obtain a bootable cd disk and insert it into the drive. Make sure in BIOS setup that the optical drive is the FIRST boot device. Then restart the machine. You will see a notice on the screen for about 5 seconds to press any key to boot from the optical drive. If the boot disk boots the system ok, you know the drive is ok and that you have a problem with configuration, or hardware connection, or you have a registry problem.

A Windows XP install disk is a bootable disk. If you do not have such disk try visiting www.bootdisk.com and see if you can download one. You may need a friend with a working optical drive in order to create a boot disk.

Please post back with the results and also tell me if the drive is listed in My Computer and Device Manager.
