Advice from Big Bill's fun factory:

A driver was loaded but Windows cannot find the device. This happens when Windows does not detect a non-Plug and Play device.
If the device was removed, uninstall the driver, install the device, and then click Scan for hardware changes to reinstall the driver. If the hardware was not removed, obtain a new or updated driver for the device.

If the device is a non-Plug and Play device, a newer version of the driver might be needed. To install non-Plug and Play devices, use the Add Hardware wizard. Click Performance and Maintenance on Control Panel, click System, and on the Hardware tab, click Add Hardware Wizard.

On the General Properties tab of the device, click Troubleshoot to start the troubleshooting wizard

Regards,

Chris McNally

Anyway I have resolve the issue:

To resolve this behavior, follow these steps:
Start Registry Editor (Regedt32.exe).
Locate the UpperFilters value under the following key in the registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}

On the Edit menu, click Delete, and then click OK.
Locate the LowerFilters value under the same key in the registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}

On the Edit menu, click Delete, and then click OK.

Wow! I had the exaxt same problem, except that mine was both cd roms. I deleted the registry entries as advised and ulinstalled the devices. Then I scanned for new hardware, and everything was back to normal in an instant!!! Thank you ernest ofori.

I had the same problem and the solution worked for me too (thanks ernest), but I was wondering if anyone knew why those registry values had to be deleted?

Amazing! I had this problem and your solution worked. Could it be caused by a virus - the timing of my cd/dvd drive crashing coincided with getting some nasty worm (which I'm not sure that I'm rid of - is it usual to have 4 SVCHOST processes running?)

This happened to me as well just today and what I had done was install ad aware and also did some registry editing last night because I tried to install dvd xcopy but had to uninstall but not before it installed a service and would not uninstall it. Both my cd and dvd rom drives would not show up and had yellow !. How did you come up with this fix?

I did not have lower filters just upper filters. How did this happen? I am fixed because of this by the way.

Thanks,

Hey, great fix action.

Could you possibly explain how the keys I deleted affected the system. Would be nice if I could explain it to the people whose computer this error was on. If not, please don't worry about it.

Nice work.

Just out of curiosity had any of you guys had problems after uninstalling Itunes?

I've seen on other forums people having problems when this happened. Im off to try the above solution, fingers crossed for me.

right okay, when i try and remove these keys i get the message cannot delete. there was an error.

this is driving me up the frigging wall, ive been on other forums and they all seem to point to the fact that apple's itunes is to blame, hence my previous post. ive tried the advice on other forums, and that led me here, cause they didnt work, but now i cant delete these registry keys, im going bananas with this!!!

Have you tried your reg edit in safe mode? The keys may be in use if you are in normal mode - just a thought.

Itunes....

That is it. I had just uninstalled it the day before. I guess that caused my problem.

I also could not delete the key and got an error message. I had uninstalled iPod and iTunes yesterday and had a suspicion that it was related. Actually I thought I must have deleted something else by mistake. After reading a few of the forums I was convinced it was iTunes. I'm not techy enough to try anything else, so I just reinstalled iTunes to see if that would work. That did it and I got both my DVD drives back.

try using regedit instead of regedt32. Make sure you have admin rights on your profile. Reboot and shut everything down. If you have a startup program that wants to use that key you will have to check the run key in your registry and maybe edit that. Also make sure that there are no services that you may suspect are using that information and at least stop them. You can restart them afterwards.

As a side note I had also F!@@#! around with Itunes at or about that time. I hate Apple for yet another reason!!!
