[resolved]CD/DVD drives are Inaccessible from "My Computer"

stevef · 04-14-2007, 10:40 PM

Trying to help a friend with her computer(Windows XP pro). The CD and DVD drives don't work and are not displayed on the My Computer page. They do show up in the Setup page and in the Device manager. In the Device manager, they have yellow exclamation points next to them and when I click on "properties", I get Code 19, which says, "Windows cannot start this hardware device because its configuration information(in the registry) is incomplete or damaged".
I looked on the Microsoft site and found some instruction on manually modifying the registry to remove the Upperfilters and Lowerfilters registry entries.
Has anyone had this problem, used this solution and did it solve the problem? Thanks!

I have seen the upper and lowerfilter entries fix some cd/dvd problems here.
After you do this, go to the device manager and delete the optical drives and reboot. See if it installs properly.

Thanks for the reply. As the troubleshooter instructed, I did try the deleting from the device manager and re-booting, but I think it said something like, "can't find a better driver than what is being used". Anyway that didn't do anything at all.
I have since used a procedure at www.support.microsoft.com . For anybody having the same problem, you can go there and look up article ID: 314060, where it shows the symptoms and resolution. This is the procedure where you delete certain upper and lower filters in the registry. In my case, the upper filters weren't even there, which is what they instruct you to delete first. I didn't know why they weren't there and was concerned that this might not work, but I decided since they weren't there, I'd go ahead and delete the lower filters which were there. Once I did that, the drives showed back up on "my computer" page and they work. So, it was pretty easy once I found the answer. It took me a long time to find the answer though
