Hi!

I'm having a problem with my PIONEER DVD-RW DVRKD08L ATA Device. I have Windows Vista on a Toshiba laptop. I hardly ever use my CD drive on here, but I was going to listen to a CD and nothing happened. So I went into My Computer and didn't see my CD drive on there. I went to the Device manager, and it seems that there is a problem with the driver software. I tried updating the driver software, but it's up to date, and I looked under properties and I saw this error message:

Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)
Click 'Check for solutions' to send data about this device to Microsoft and to see if there is a solution available

I clicked 'Check for solutions' but nothing happened. What's going on and how can I fix this?

Thank you!

Hello flutie_flutie...

Click Start, then Run, type regedit and click "Ok"

In the left pane, expand (click +) HKEY_LOCAL_MACHINE, then SYSTEM, then CurrentControlSet, then Control, then Class, and click on {4D36E965-E325-11CE-BFC1-08002BE10318}

In the right pane, are UpperFilters and/or LowerFilters listed?

Sorry to intrude, but what does it mean if those are listed?

[flutie_flutie]

wannabe1, both are listed

In the left pane, right click on {4D36E965-E325-11CE-BFC1-08002BE10318} and choose "Export". Name this file oldfilters and save it to your desktop.
In the right pane, right click on LowerFilters and choose "Delete"...accept the change. Right click on UpperFilters and choose "Delete"...accept the change.

Close Registry Editor and reboot.

Does the drive work properly after rebooting?

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

UpperFilters and LowerFilters are hardware hooks that some software applications use to utilize a device...in this case, the optical drive. If the application is removed or becomes corrupt and is no longer used, but the filters are still in place, the computer will see the call for drivers, but not be able to find them...so the device fails to initialize.

awesome! thanks for the explanation too!

Great!

You can delete the file you saved to your desktop...it's no longer needed.

I had a similar problem and followed the directions above. Now in "My Computer" The CD/DVD drive appears, which it didn't before, but it still wont play my CDs.

I have an e-machine t6414? with Windows XP should my directions have been different?

I can hear it trying to run, but then it goes "ernk" and doesn't.

thank you sooo much! I was really upset that my driver had been corrupted but now it plays cd's again but itunes keeps saying the drivers needed for importing music are missing and to reinstall itunes.

Wannabe 1,
I joined this forum just so I could tell you thanks! I had the same exact problem, same system, same computer, etc. The only difference is that I use my drive all the time. I just reformatted my entire laptop to get a bunch of unnecessary junk off of it. Evidently, lovely Vista thought my driver for my CD Rom was junk. I know Java and a few other languages, among other things, but I had no clue what to do when I couldn't find a replacement driver.

So, thanks for the awesome answer and teaching me something new.

And now, off to kill some Zerg...
