DVD/CD Drive Error - Code 19

Hi,

Roxio, or other players/programs that use the drive, could be the cause and you may need to
uninstall them and then run through these a 2nd time.

Code 19 means there is a driver conflict such as two devices trying to use the same resources.

Stage 1 : Please do all the below even if you have done some before as it is often the total process which
solves the issue.

Try this - Control Panel - Device Manager - CD/DVD - double click the device - Driver's Tab - click
Update Drivers (this will likely do nothing) - then RIGHT CLICK the drive - UNINSTALL - REBOOT
this will refresh the default driver stack. Even if drive is not shown continue below.

Then work your way through these - remember the drive could be bad, could have a loose cable or
slight corrosion on the contacts (usually for a laptop) and other issues.

Another possibility is that the cables are loose. Remove ALL power, then check cables in both
ends. Remove and replace, do not just snug. For laptops you can often clean the power and
data contacts with a pencil eraser.

Some DVD drives do not use the Windows default drivers so check with the System maker and
device maker to see if there is firmware or drivers for you drive if needed.

===============================

Stage 2 : You could have drive issues as the CD/DVD is actually 4 drives in 1 case ( CD & DVD burn and
CD and DVD read). So it is not unusual for 1 or 2 parts to not function while the others do so properly.

Did you complete the troubleshooter for the drive that still does not work? There are some registry entries
that the troubleshooter does not fix and those "might" be the cause.

Check with your System Maker and Device maker for both possible firmware updates and the correct
Registry entries for your drive.

These are the keys I think are the ones in question - for the CD/DVD drive sub-keys of course as there will
other sub-keys in these keys. Be sure to ask for specific keys involved as well as the settings.

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\IDE

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Hardware Profiles\0001\System\CurrentControlSet\Enum\IDE

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}

You probably can find more info here and maybe even the exact registry settings for your CD/DVD drive
from someone with the same model.
