Repair Inaccessible CD / DVD drive.

If the CD or DVD disc drive becomes inaccessible when an attempt to use the drive is made the following error is displayed:

Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19)

The mechanism for repairing this fault is to remove the appropriate registry entries to enable Windows to re-instate the correct values following a reboot.

  1. Select Start / Run / type Regedit / click OK
  2. Within the registry editor Navigate to and click {4D36E965-E325-11CE-BFC1-08002BE10318} (there are many similar looking entries so be careful - you only need check the 4D36E965 in the list and not the whole number). The location is:

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11C
    E-BFC1-08002BE10318}
  3. Before any changes are made backup this registry key: Right click{4D36E965-E325-11C
    E-BFC1-08002BE10318}
    choose Export and save the file to your desktop, for example as cdinterface.reg. This registry backup may be restored by double clicking the saved registry backup file and choosing Yes in the unlikely event of an error.
  4. Right click LowerFilters / choose Delete / then Confirm
  5. Right click UpperFilters / choose Delete / then Confirm
  6. Reboot the PC.
