Pioneer dvd-rw dvr-k17a

I have the same problem and found a solution that works beautifully

To resolve this problem, remove the affected filter drivers. To do this, follow these steps: 1. Click Start, type regedit in the Start Search box, and then click regedit in the Programs list.

If you are prompted for an administrator password or confirmation, type your password, or click Continue. 2. Locate, and then click the following registry subkey: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}Caution There can be many instances of the registry subkey that is mentioned in step 2. You must make sure that you are in the appropriate registry subkey before modifying the UpperFilters and the LowerFilters values. To verify that you are in the appropriate registry subkey, make sure that the Default data value is DVD/CD-ROM and the Class data value is CDROM. 3. In the right pane, right-click UpperFilters, and then click Delete. 4. Click Yes to confirm the removal of the UpperFilters registry entry. 5. In the right pane, right-click LowerFilters, and then click Delete. 6. Click Yes to confirm the removal of the LowerFilters registry entry. 7. Exit Registry Editor, and then restart the computer. Note After you remove the UpperFilters registry entry and the LowerFilters registry entry, you may lose functionality in certain programs such as CD recording programs. In this scenario, you must reinstall any affected programs. If the problem recurs, contact the program vendor to determine whether an update is available for the program.

close the regedit and restart the windows.

hope i can help u guys. it worked for me.

the drive is not recognized by the os, cant run any disc, i have checked in device manager it says;Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)
I have a Pioneer DVD DVRKD08L ATA DVD playe

The solution is as TMYERS12 states and is not that hard. My Toshiba laptop had the same problem and was under warranty so I rang Curry's. They knew about the problem and suggested I delete the registry keys. It's caused by downloading additional software - mine was caused by ITUNES adding additional code to VISTA!!!

I have a Toshiba A305 S6825 with a Pioneer DVD DVRKD08L ATA DVD player but no disc will work . When i go to device mgr it reads "windows (39) cannot install driver.

Hello! I have a laptop Toshiba Satellite A135-s4427, Same thing happen the way u describe, Windows failed to load drivers and I was about to burn a dvd when it happen like that, I surf net to look for solution but they didnt work, i dnt know about registy, I then got a solution, of course the last solution one can possibly take :), I backed up my important files to a media drive, Put my Recovery Discs and made an out-of-box recovery of my Laptop... Its Worked for me!!!

Just go to regedit and find this sub root " HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318 " and delete the upper and lower filters, just be aware that if you use the registry optimization software then this problem will result again and you have to do the same thing again , good luck

i have a toshiba laptop model satellite P200-13F and a few days ago i've had the same problem , so please i'd like to resolve it as soon as posible .
Many thanks

Thank you so much, i could solve my problem as well!!!
