Note : 
This solution is taken from http://h30434.www3.hp.com/t5/Notebook-Hardware/DVD-CD-ROM-device-driver-corrupted and hopefully it can solve your issue.

Question 1 :
 
I have a HP Pavilion dv6853cl notebook, Vista (64-bit). The DVD drive is listed in Device Manager as Slimtype DVD A DS8A1H ATA Device and reports "Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)".

Is there a way to download a new/updated driver or a registry update for this device that will resolve this problem?

Solution : 

Optical drives do not need drivers as such to be seen in the device manager....they are activated by the OS at a very low level. But XP and Vista are prone to occasionally losing them and you need to do a registry hack involving removal of the upper and lower filters. Here is the info you need:

UPDATE
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11­CE-BFC1-08002BE10318}
Apparently it seems that this is an age old fix for even XP systems. If you venture to the registry key above by doing the following steps:

1. Click on the start menu.
2. If this is a Vista machine in the search box type in “regedit” without the quotation marks.
3. Maximize the HKLM and then go ahead and browse until you reach the key listed above.
4. In the right panel you’ll see something along the lines of “UpperFilter” and “LowerFilter” you want to click on each “filter” key and hit delete. Click yes when it asks to confirm if you wish to delete the key.
5. Restart Windows.

Question 2 :

I am having trouble with a CD - Rom driver on my HP laptop.  Specifically, I am dealing with a Slimtype DVD A DS8AZH ATA device.  It has been giving me trouble for some time, I even returned the computer to HP, got the mobo replaced, and it is still giving me problems.  After uninstalling the device and restarting the computer, I get an error prompt stating:

'Device driver software was not succesfully installed'
Please consult with your device manufacturer for assistance getting this device installed.

 I do not to send my computer off for another three weeks, espcially if HP isnt going to fix my problem.  Can anyone please help me or at least point me in the right direction? 

Thanks a bunch!

Solution :  


code 39 means that the filters for the DVD rom drive have become comprimised. You must have installed some type of burning software. you need to make a registry edit.

WARNING: EDITING THE REGISTRY MAY CAUSE UNDESIRABLE AFFECTS ON YOUR SYSTEM. FOLLOW THESE STEPS EXACTLY AS SHOWN

1)Click start
2)type "regedit" without the quotes
3)above in the programs list right click on regedit and click "run as administrator"
4)click file and click save to make a backup of the registry incase you mess up
5) go to this path
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}
 6)click on the file that states 4D36E965-E325-11CE-BFC1-08002BE10318 and look at the right hand side
7)right click and remove anything that says "upper filters" and/or "lower filters"
8)close out of registry editor and restart the notebook
9)Your issue should be resolved

Your burning software will need to be reinstalled.
