  • khasey I am having the same problem, it just started today when my wife tried to install some software.  My system dual boots, so I could test it in XP Pro.  XP has no problem seeing the drive or using it.

    Did you ever get an answer or figure out how to fix this?

     

    Thanks,

  • Hey!  I figured out how to make it work - At least for me!  I copied part of the article & pasted it below.  It states that it works on XP, but I've tried it on Vista & it worked right after the restart.  It was a registry I needed to delete - It mentions below deleting entries in that key, but I only found the second one mentioned "LowerFilters registry ", but I went ahead & tried it.

    I thought you might like to know.

    If a CD recording program no longer works after you restart the computer, you must reinstall the CD recording program.

  • I am curious about the above "Code 39" fix. When I went to the support Microsoft site, it mentioned Code 31 and Code 19, but not Code 39. I am having a spot of bother in that as I cannot get my DVD/CD ROM to work, I cannot install anything.

  • If you haven't fixed your code 39 yet. I had it happen to me today, and deleting the regestry like what the posts have been saying did work for me. just reboot afterwards and vista reinstalled the right drivers and now i'm up and running.

  • I had  the code 39 error and your registry editing solved my problems for both my  CD-RW and DVD/CD-RW.  I am a Win XP pro user. Thank you for the work around

  • It has taken me 3 days to try and figure out what the code 39 was and how to fix it. I just happen to come accross this forum page by accident and found the answer I needed. I followed the directions for the regestry deletion and when I restarted the unit, there was my icon back and the properites tab indicated that the device was working properly.  I am a Windows Vista home version user and it works great now thank you very much for the information.

  • Thanks alot. This worked great on my Vista Ultimate. Updates tend to drop hardware alot so I hear from a techie. I appreciate the info.

  • Thanks for the information on this error, as I didn't know a fix for it.

  • Very very nice. In my lower registry I at once saw the registry entry was a DVD burning software I use. it all made sence because i just upgraded to Vista Home Premium and had not used this partucular software yet. Right after I initialy tried my software is when my dvd drive disappeared. Anyways, I as well only showed the "lower registry" entry. I deleted it...rebooted and bingo all is well. Forums works if you take the time to read and learn.

  • This fix works!!! Just be careful not to delete ALL entries of upper and lower filters, only the two that this fix calls for.  Thank you so much, roystreet!!

  • Thanks for the tip!  With Vista Ultimate SP1 I didn't have the upperfilter file.  But I deleted the Lowerfiler entry just as you instructed, rebooted and the drive is back and working fine.

     

    Thanks again for your help!

  • Amazing!  I wasted the better part of a day going through Microsoft's alleged help files before I accidentally stumbled into this forum and found the solution to my problem.  I have Windows Vista home edition and my CD/DVD problem was fixed after I followed these steps.  Thank you!

  • Thanks, it worked.  Only thing I did differnet is disabled, then enabled the cd & dvd drives in my device manager.  There was no need to reboot - a big time waster.

  • I tried this step, and after restarting, I still get the same error. I am using Windows XP Home Edition with Service Pack 3. Is there anything else that can be done?

    Sunday, August 31, 2008 3:39 PM
  • This information was very valuable to me as well. I too am using Windows Vista and was getting the 39 code and after performing the simple instructions I am able to utilize my cd/dvd drive again. Thanks!

  • I have the same problem as you. Tried this step, even updated my firmware, still have the same problem. I am using XP home edition with service Pack 3. I even tried another cd, same problem. What did you do to fix your problem?

  • I unfortunately ran the guided help to resolve the code 39 error, now I cannot boot my PC. It stops on the BSoD.  Any ideas on how to get past this?  I cannot even bring up safe mode.

  • Had this problem before with my laptop after removing Roxio 9, but reinstalled XP because I wanted to upgrade to Vista. Got it again today after removing iTunes a day or two ago, and tried several tricks to try and get my DVD drives to detect, and none of them worked. I then searched Microsoft's website for the Code 39, hoping it would provide some insite on how to help me fix this problem, and found this post on editing the registry. Tried it and worked like a charm. If my search had failed, I would've tried calling Microsoft themselves for help. Saved my $39.

     

    Thanks a bunch.

  • Thanks for the advice!  I have Windows Vista, too, and your instructions totally helped.  I am so glad!!!  Take care.

  • Wow thank you sooooo much for your post, I was getting nervous about my driver but it works fine now, it was a little confusing though, only because there are two parts under System; ControlSet001 and ControlSet002, I removed both upper and lower filters to Class {4D36E965-E325-11CE-BFC1-08002BE10318}But once I restarted the computer I ran my program and the driver was located.

    Thank you again!

  • Dude, you are a genius! You have made my all day search wothwhile. I have a MATSHITA DVD-RAM UJ-830S and I thought it was the hardware but it was not. The hardware works fine. That fix that you have posted solved the problem. Now I can finally read discs again. Thanks! You are awsome!
    Sunday, October 26, 2008 2:12 AM
  • Wow, Thanks heaps Roystreet ^_^ I'm a bit of a sceptic when it comes to online help like this, but I tried your instructions and it worked like a charm!! Back to working as soon as i restarted. Thanks again.

  • I deleted the upper and lower as instructed and am still getting the same eror. I did notice there were multiple sub folders containing the exact same data without the upper and lower filters. Cuuld this be the problem? If not does anyone have anymore suggestions. I just purchased a digital photo key chain and it gives me the same error.
