I have a HP Pavillion Desktop a6620f purchased in December. Everything worked fine, until one day I want to play a CD and I see that the computer does not recognize the drive. I went through the diagnostics, and it gave me error 39: does not recognize drive.
Went through all the steps to uninstall and reinstall CyberLinkPower2Go driver, and still no drive. The hardware seems to work, it is just the computer does not see the drive.
Everything else works fine, I can play iTunes, etc with sound.

The code 39 error generally occurs due to upperfilter and lowerfilters key in Registry.
Do the following steps to check if you have the keys and delete them if it is there.
Click on Start and type regedit in the search box and hit enter.
It will open registry editor.
In registry editor, please click the plus sign ( + ) next to the following items in the list:
Select 4D36E965-E325-11CE-BFC1-08002BE10318 . Make sure you have selected this exact key name.
Look at the right pane and check if you have upperfilter and lowerfilters keys.
If they are present delete them.
Now Click oN Start and in search box type device manager hit enter.
It will open device manager window.
Click on + sign near CD/DVD drive and right click on teh drive name > select uninstall.
It will remove the cd/dvd drive from device manager list.
Now click on action > scan fro hardware changes.
Voila you will get backl the drive name without any excalmatory mark.
Check now it will read all teh disks.
let me know if it worked.

Finally took the time to fix my CD/DVD drive and your suggestion worked! Persistence paid off...none of the "fix-it" websites helped AT ALL until I found your post. My list had upperfilter keys and once deleted my drive finally works again! Thank you SOOOOOO much!
