Fix missing DVD/CD drives not showing up in windows explorer

Post by Doctor Inferno on 16th April 2008, 1:35 pm

It is very common these days to be using Windows 2000/XP/Vista and have your CD/DVD drive stop functioning. There are various causes; from loose power or IDE cables, to broken drives, to corrupt drivers. The latter is the most common.
Often times, someone has upgraded from a previous Operating System, or installed (incompatible) CD/DVD burning software, when this problem rears its ugly head.

The reasoning? The drivers from these type of applications are typically incompatible when you upgrade your OS. Alternately, its not unheard of them to corrupt. When these drivers do not work--they take most, if not all, of the CD/DVD drive functions with it. It is pretty easy to identify these problems, if you check Device Manager, you will often find a '?' or '!' next to the device. Common error codes are 19, 31, 32, 39 and 41. Also, you may find that your drive disappears from My Computer altogether.

The fix sounds complicated, but we have made it easy for you. There are two ways to do this. Manually edit the registry and remove the bad values, or simply download aregistry file and merge it with your own. We urge you to backup ALL of your data beforehand. We will take no responsibility for data loss! Also, it is reccomended to backup your registry.

Warning! Any CD/DVD writing software not built into Windows will need to be reinstalled after this procedure.

First method

1. Go to start, run and type regedit. Locate the key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}.
Locate the values on the right for UpperFilters, and/or LowerFilters. Remove these values, then reboot your computer. Be careful here, there are very few second chances when it comes to the registry.

Second method

1. Download these registry files. Unzip them, and then double click to merge. They will remove the offending entries. Then, reboot your computer for the changes to take effect.
