DVD drive not recognized

I have had Windows 8 Pro for a little more than a month and there was no issues however as of December 31,2012 the computer does no recognizes DVD/Cd's. i had tried going to Control Panel and did troubleshooting under  Hardware and Devices. What popped upped from that was Driver       HL-DT-ST DVDRAM GH70N had problems. There were no fixes to this.   

Also at Device Manager it said Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19). There was no update to fix it.

I have also tried doing this reg.exe add "HKLM\System\CurrentControlSet\Services\atapi\Controller0" /f /v EnumDevice1 /t REG_DWORD /d 0x00000001
 when i did it reg.exe add "HKLM\System\CurrentControlSet\Services\atapi\Controller0" /f /v EnumDevice1 /t REG_DWORD /d 0x00000001 It said The operation completed successfully 

This computer is an Acer Aspire X3950. it was upgraded from Windows 7 to Windows 8 Pro by Disk. 

Have you installed any CD/DVD type programs just about the time this happened.
Some compete for resources, especially those in StartUp, and can cause this and
other related drive issues. iTunes is an example but not the only one which can
play a role in these issues.


Check with Acer Support, their on-line documentation, and drivers.

Use this :

What if a device isn't installed properly? (Run the Hardware and Devices troubleshooter)


If the above did not help try a System Restore :

How to Do a System Restore in Windows 8

If the Restore works or not the issue might be related to a Windows Update that was installed
just prior to this happening.

To check and even remove a Windows Update :

Control Panel - Windows Updates

Lower left corner - Installed Updates - check the dates and you can remove it if needed.
If you remove an update and it is offered again (run check for updates) then you can use
"View update history" and Right Click on one and HIDE.

Troubleshoot problems installing updates _ "I keep being offered........" shows how to HIDE.

Windows automatic updating: Frequently asked questions


If nothing else works try a Refresh or even a Reset :

Windows 8 includes special methods to Refresh (keep files and settings)  or a Reset
(new install removing all).
