If you have a Vista system and your CD Rom drive does not seem to be reading any discs then you have an upper stack error. Common error codes are

The device is not working properly because Windows cannot load the drivers required for this device (Code 31).

A driver for this device was not required, and has been turned off (Code 32 or Code 31).

Your registry might be corrupted. (Code 19)
The most frustrating part is I have had several Toshiba customers call me about having this issue on brand new laptops. The good news is it is a simple fix that anyone can do.

First lets confirm your issue. Right click on “Computer” or “My Computer” in XP. Select Manage and then on the right side select device manager. On the left if you see a yellow exclamation mark next to your drive and were getting any of the above error codes then we have a simple fix.

Go ahead and right click on the CD or DVD drive that has a yellow exclamation mark next to it and select delete or remove.

For Vista click the windows “start” button on the bottom left and in the search box type regedit . You will be asked to confirm your admin account. Just hit next or continue.

Now browse to



It’s just like browsing through folders so don’t worry about it. if you get lost just start over. BE SURE you follow the path 100% There are many similar files and folders so double check they all match up.

Now that you are at the 4D36E965-E325-11CE-BFC1-08002BE10318 Folder on the right side you will see several entries. right Click and delete the Upperfilters and Lowerfilters. These will be remade once you reboot.

for XP follow the above but instead click the windows start button and then select run then type regedit .

Reboot your computer once you have removed the upper and lower fillters. When your computer boots back up it will see the drives as new devices. give it another 20-30 seconds to install the new device. badda bing badda boom! your issue is solved.
