No Upper/Lower filters - still an error

by snoopyloop / September 18, 2008 12:09 PM PDT

Hello everyone.

I've searched around the XP forums for advice about my problem, but haven't found one just like mine. So here it goes..

My CD drive stopped working properly (it had an error 31). My computer basically stopped reading my CD and DVD drives, and no disks can be read - even though they will are being spun. So I followed the advice given by Microsoft in their help forum. It was to delete the upper and lower filters in HKEY_LOCAL_MACHINE-SYSTEM-CurrentControlSet-Expand Control-Class-{4D36E965-E325-11CE-BFC1-08002BE10318}.

When I went to that folder I had no upper filter listed, but had a lower one, so I deleted it. (I did make a restoration point beforehand). Then I restarted my computer but now it will still not read either my CD or DVD drives. I can not find any advice further than just deleting these filters anywhere!

Does anyone have any clue what I could do to fix this problem? I would really appreciate any help.

I have a Dell Dimension 4600, running Windows XP. (I'm not sure what other info would help here?) Thanks for any input!!

I followed the link to Microsoft, I had it fix the problem automatically, and it said it completed it correctly. Then I went through the steps that you said afterwards.

I rebooted windows in safe mode and deleted the cd and dvd drives. Then I rebooted in normal mode, and windows found my cd drive, but not my dvd drive at all!

Also, the cd drive doesn't seem to read the cd I insert automatically. I have to go to My computer - click the cd drive - right click properties - go to hardware, then "populate the volumes" of the disc to read it.

I can put up with that, but do you have any idea how I can get the DVD Rom back??

Your DVD-drive seems defective. A new one might very well work.

"populate the volumes". That's strange. All I have on the hardware tab of the properties of the CD-drive is the problem solver, no "populate". In google, I find a few references to 'populate the volumes', but most seem to be about a hard disk.

- Did you try the problem solver?
- What kind of CD is it: a retail music CD, a retail data CD (like a CD to install Windows or a game) or a CD you burned yourself (if so, what burning program)?

Your post is a little light on the connections to the CD and DVD drive.

If this was my machine I'd test each drive ALONE on it's IDE cable jumpered PROPER for the cable type used. I'll skip any lesson in IDE cable technology and how 80 and 40 conductor cables change what choice we make on the jumpers.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
