My Computer does not show CD or DVD drive in Windows XP

October 14th, 2010. Published under Uncategorized. No Comments.

I have seen this a few times in recent months, so it is worth documenting. The CD or DVD drive does not show up in My Computer, and in the Device Manager it is showing a warning (yellow circle with black exclamation point in it). The description of the warning states something about the drivers being installed but the device is not present, when the device is most certainly present.

The fix is a registry hack. Be sure to export this key before making deletions, in case things go awry. The key to navigate to is:


Delete the following values in the right pane.  Note that both values may not exist.

  • UpperFilters
  • LowerFilters

Restart the computer and your drive letter should return.

CD / DVD drive missing / not recognized by Windows

Recently an associate came across this issue, where a Windows XP laptop was not showing a drive letter for the DVD drive. The drive was obviously powered since it would open when the eject button was pressed. In Device Manager, the drive was showing the yellow exclamation point symbol for a device that had a driver issue. The usual action of deleting the device in Device Manager and restarting did not change this; it just came back with the yellow exclamation mark.

Googling for this issue let to several forum posts where the solution was a quick deletion of two values in the registry. The solution, which works for Windows 2000, Windows XP, Windows Vista, and Windows 7, can be found at the Microsoft Support site.

A quick reboot after the registry deletions fixed the issue on this laptop.
