Thanks for this solution!!
I had the same driver error code 39, except that it wasn't my dvd-writer, but it was my Realtek High Definition Sound drivers which said were corrupted...

So i did the same with the regedit, but instead looked for Drivers for sound, video and games, I deleted the Lowerfilters entry and rebooted, and instantly got my sound back

Now if I play an MP3 with WMP 11 it plays with cracks and hisses, but when I use another Media Player it works perfect, and it never did untill I updated to WMP11.

But anyway, many thanks, saved me from reinstalling XP!

Erdiko you're a genius. Here we are years later and your fix is still helping people! I just had to create an account to thank you.

Edriko, MANY, MANY THANKS!!!! Oh, boy. I googled for hours and gave up. Then I tried to google to re down load my XP drivers and I came across this thread. IT WORKED!!!!!!!!!!

I was a little worried because I did not have "lower filter" in my registry, but it did not matter. I did use the link to the MS page so the steps were clearer. No problem at all.

Don't you just hate laptop tech help (mine was ACER) whose solution is always to do a FULL SYSTEM RESTORE. You know, just when you have spent 8 months downloading all your software and tweaking everything just right. GACK! I hate them.

I had this same E drive problem a month ago that I fixed with a simple rollback system restore to a few days earlier, but this time I had just deleted all my restore points thinking my system was A OK. WRONG. I had the dreaded code 40 or 41? that said my system had good drivers but could not find my hardware.

Perhaps it was caused by a registry repair by Crap Cleaner that I did with out a back up. Shame on me.
In any event, Medal of Honor to Edriko! Yea!

Hi Folks,

I've tried everything listed here but I am still having problems.

My problem occured after a crash and having to repair my system but it seems slightly different. I first noticed the issue during the repair process - and tried the Upper/Lower filters repair with no luck.

The system has been updated to all the latest patches off Windows Update.

Basically I can see both of my CD drives (well one CD-RW and one DVD) in Windows. I can play music CD's in both and see the drive letters. Windows can also detect whether a disk is loaded. It can also detect a blank CD and asks me what I want to do with it. However, when I try to read a data CD (or video DVD) it gives me an error about the data being corrupt. This is with any data CD including the original XP disk.

I can boot of the CD and run Recovery Console or a Windows Repair.

I have installed a clean copy of Windows XP on a spare disk and that reads both drives fine. I just don't want to re-install my main copy due to the several days it will take me to re-install all my apps.

Thanks.

Me too! It fixed my 'error code 39' problem. (It seems like it's fixing problems about disappearing Dvd drivers from My Computer, that gives bunch of different codes.)
Although It would be hard for me to just read and apply Erdiko's info since I am not very good at Registry poking. But someone along the line to acknowledge him also gave this link to http://support.microsoft.com/kb/320553/ which explains for dummies:) So thanx to everyone and Erdiko if he reads these anymore... By the way is it stupid or is it just me? When you make a search about code 39 or any other code in that matter Microsoft gşves you nothing, as it doesn't even exists! There are many little and big, wacky problems like this one with XP, and the help data base probably has an answer, yet you can not find it, it's unreachable! XP sucks yes we know at least 'help' should bring some help right ?

OK - The fixed worked for me also, Many Thanks Edriko, however this is the strange part I have a desktop PC and a laptop and the error occurred on both devices on the same day. The laptop wasn't even connected to a network nor had been for two months prior. Now what are the chances of two devices having the same problem on the same day in the one household??
Could this problem be a virus that is date activated as the CD, DVD and virtual drives stopped working on the 1st of April??
Certainly sound like it to me - although I have not been able to find a virus program that identifies it as such.
Confused..........

Hi, I'm getting the same error code 39 on my lan adapter, it's on board so i thought there was a problem with the motherboard so i bought a pci network card to try and get around the problem but sure enough when i tried to load the drivers it came up saying (windows cannot load the device driver for this hardware the driver may be corrupt or missing error code 39) is there any fix for this i'm going crazy any help would be grateful.

After applying Edriko's fix I can now read CDs (woohoo!) but the system now thinks that CDs are hard drives. Screen shot:


When I first perform the fix, they show up as CDs like they should, but as soon as I insert a disk they turn into hard drives (XP calls them "local drives" as you can see).

That ordinarily wouldn't be a problem but the first thing I notice is there is no right-click->eject option, the second thing is autoplay no longer works, and finally they get a warning about low disk space (because it thinks it's a hard drive that's 100% full).

I think Windows is boogered up but I really don't want to go through another reformat + reinstall, I just did it a month ago and this system has ALOT of software to reinstall, reregister, etc. Ugh.

I tried deleting the whole key and restoring it from another computer. Same thing.

I just got done running sfc /scannow, no help.

I do reboot after I do anything to the registry, and I uninstall/reinstall through hardware detection.

I only found one Google post on this exact issue and I fear I won't get a response from the original poster.


As a possible clue, UpperFilters and LowerFilters never comes back when I run hardware detection. Perhaps someone would like to post the values of those items in their registry? The working computer I copied it from does nohave UpperFilters, only LowerFilters, and actually the value of LowerFilters was identical to what it was when this whole mess started (I saved and compared a backup .reg file).

Ideas?? This is maddening.

I, too, joined so I could add my thanks to Erdiko. Only wish I had found his solution before buying a replacement for my DVD burner.

I'm not a member, but I thought that I would sign up just to reply to this. Dude, this advice rocked. I was very hesitant to delete these, but I'm glad I did. It saved me a ton of work and money. Thanks for your help.

I went to HKEY_LOCAL_MACHINE/SYSTEM/CONTROL/CLASS/{4D36E965-E325-11CE-BFC1-08002BE10318} and found three sub files, 0000;0001; and Properties. 0000 and 0001 are linked to the same keys. Default, 4 driver keys, enum, 2 inf's, matching Device and Providername. Apparently, not all systems contain the words "upper and/or lower filters".
Since the words upper and lower filter do not apply in this type of system(XP upgrade from Win98M), which keys am I supposed to delete? No trial and error here. Also, reformatting is not an acceptable option. (not my computer)

For those that cannot find upper & lower filters, follow the string as shown before, HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/control/Class/{4D36E965-E325-11CE-BFC1-08002BE10318}. Right click on the number string. Click find. Type in upperfilter. Click find next. Upperfilters will appear. When finished repeat process and type lowerfilter. It will appear. Upperfilter and lowerfilters will not be in the same window at the same time. Unfortunately for me, I couldn't delete lowerfilters. Not all values, anyway. I deleted upperfilters and rebooted. It reinstalled the cd rom and the same thing happened. Drivers corrupt or missing.

This was a MAJOR life saver. I got backup HD's but I just didnt wanna reinstall all my stuff.
a lil tip: I got like 15 of the same registry key. If this is like u also only deal with the one with the CD/DVD name. (in the 3rd column under Data)

Again, thanks so much for this tip. I remember having to reinstall becauce of this a few years ago. Not anymore now!!!!
