  • Go to HKEY_LOCAL_Machine\System\CurrentControlSet\Services\atapi\Controller0
  • Create a new Dword value (same bit version as for your system).
  • Rename it as "EnumDevices 1"
  • Double click on the EnumDevice1 and set its value to 1.
  • Close the registry and restart your system.


Instead of using the registy, you can use the following command:

  • Open an elevated command prompt and enter the above command.
