I have a Windows XP pro HP machine and the DVD is not working.  Have gone through all Windows updates and HP updates.

Device Manager says it is an HL-DT-ST DVDRAM GSA-4084N device and the status is "Windows cannot load the device driver for this hardware.  The driver may be corrupted or missing. (Code 39)"

Do not have any other documentation and drive does not have manufacturers label that I can see.

Where can I get plug and play CDROM/DVD drivers??  Thanx...........  phil_vIn Device Manager right clik the drive and select Remove/Uninstall...
Optical drives haven't needed drivers since before WinME.
Windows will automatically re-install it upon re-boot.

You may also want to consider the drive is getting ready to fail if it's 3 + years old.I have tried 'disabling' and I have tried 'uninstalling' and then reenabling and reinstalling.  I got Bupkis....  keep getting the same message in Device Manager.  Does this mean I need to replace the drive???.........  phil_v One of these may help:

1. http://support.microsoft.com/kb/314060
Restart computer.
or...
2. Download, and run Restore Missing CD Drive patch
Double click on cdgone.zip to unzip it.
Right click on cdgone.reg, click Merge.
Accept registry merge.
Restart computer.
or...
3. Go to Device Manager, click a "+" sign next to IDE ATA/ATAPI Controllers.
You'll see two items:
- ATA Channel0 (or Primary Channel)
- ATA Channel1 (or Secondary Channel)
Right click on each of them, and click Uninstall. Confirm.
Restart Windows. They'll be automatically reinstalled.

If none of the above helps, most likely, you need a new drive.If Broni is correct and the M$fix utility doesn't do the trick then you might want to try the suggestion below.  I pulled this together and added it to the solutions database where I work:

Symptoms:
CD or DVD drive will cease to exist on the affected machine.  Errors may or may not exist on the affected machine.

CD or DVD ROMS will not be visible from the device manager or YELLOW exclamation points are SEEN on every CD and DVD-ROM available.

Cause:
Programs, such as decoders and burning software, sometimes register ‘filters’ that load either before or after the CD or DVD ROM subsystem in Windows.

Sometimes when uninstalling software, they will remove the filter that was registered but leave behind the reference to the filter in the registry.

Warnings:
The solution for this problem requires changes to the registry to resolve.  This can be dangerous if mistakes are made.  Please backup your registry before attempting this procedure or have a qualified computer technician work on it.  *Organization where Sn3akyP3t3 works* will not be responsible for damage resulting from actions followed in from the information that is provided in the procedures given for solutions.

Notes:
The solutions have been tested on Windows XP machines by one of *Organization where Sn3akyP3t3 works* IT department student workers and are known to work with that Operating System.  Reports found in many forums indicate that this procedure works for Windows Vista based machines, but Microsoft has not indicated that this procedure works for Vista.

This problem does not fix broken hardware.  If the drive does not function after attempting the procedure then please invoke your computer's warranty or seek qualified hardware repair.

Solution:
The following sites have methods for resolving this problem given in order of preference:

Microsoft has a free utility called 'Microsoft Fix it Center'.  It found:

"CLASS filter drivers are corrupt                                  Fixed 
 
One or more class-specific filter drivers are missing/corrupt"

It corrected the problem, now the drive works fine. 

This utility will also analyze print, audio, IE freezes, Video freezes, as well as CD/DVD problems.  Pretty COOL..

Now I just have to find out where to buy a new HP 17.2" LCD SCREEN (HP doesn't have them, nor does the hardware vendor they recommend)cause mine is failing. 

Thanx for your help, I'll post my LCD problem on the appropriate forum....  phil_v
