Title: dvd / cd roms not working
Post by: TR on March 13, 2011, 19:15
I have a weird problem  ;D  no not me.

Friend gave me her PC to look at saying that the CD / DVD players dont work?  and she was correct, took them out booted up and reinstalled again saying found new hardware etc, but still doesnt work. The PC sees them and will eject the tray but wont recognise any discs?

I have tried putting them in an old tower I have and they work ok..weird huh, friends PC has all the latest drivers etc..anybody have any ideas on what could be the problem.


This has got me baffled  :stars:

If you go to the properties of each drive, then click the Auto Play tab, there might be some settings there that could be tweaked.  Sorry to be vague, I'm not on the PC at the moment.

I was going to suggest checking cables and jumpers, but I wouldn't have thought they'd work at all if they were wrong. 

Something like this came up before, and I seem to recall there's a registry entry you can either change or remove, for it to be reset.

What OS is this, Terry?

Post by: TR on March 13, 2011, 23:10
changed/deleted the upper and lower filters in the registry  ;D

This is a XP set up

the fact that it worked on installing suggests XP is to blame...

.. oh I see the last post.

Damn, I was just going to do my conjuring trick. ;D

If DVD/CDs become ‘lost’, code 39 error “Windows cannot load the driver. The driver may be missing or corrupted (Code 39)”.

Go to Device Manager, uninstall CD & DVD drivers. Uninstall Primary and Secondary IDE channels under IDE/ATAPI Controllers - ignore requests to re-boot machine.

Go to Regedit, navigate to key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}

Look for the key which refers to DVD/CD-ROM drives. Delete the subkey UpperFilters, also LowerFilters if it is present.

Re-boot the machine. All should now be well.

I know you've tried the drives on another machine, but have you tried another drive in that machine?
Title: Re: dvd / cd roms not working

It does seem to be pointing at the controller, doesn't it.
Title: Re: dvd / cd roms not working
Post by: TR on March 14, 2011, 20:12
This is driving me bloody mad  ;D

I have had other drives in said machine and same thing  :bawl:


What Controller?  ;)

Post by: Simon on March 14, 2011, 23:32
In Rik's case, a fat one  :laugh:  but I was wondering that too, Terry.  :dunno:

I've done a few Google searches on this and haven't come up with anything you haven't already tried.  :(

The disk controller.

As in the I/O thingy whatsit?
Title: Re: dvd / cd roms not working
Post by: Rik on March 15, 2011, 09:33
The very same.
Title: Re: dvd / cd roms not working
Post by: Simon on March 15, 2011, 11:08
So, what does Terry need to do?
Title: Re: dvd / cd roms not working
Post by: Rik on March 15, 2011, 12:20
If it is the controller, it's probably motherboard based, so the solution would be to disable it and fit a separate controller card. The only other thing I can think is to try a Windows repair, and if that doesn't work, a full re-install.

Post by: TR on March 15, 2011, 12:22
Delete ide controllers and reboot  ;)

That too, Terry. ;D
Title: Re: dvd / cd roms not working
Post by: TR on March 15, 2011, 20:00
Nope ..that didnt work  :laugh:

Just put the 2 said Drivers into a spare pc running Vista ....and all ok.

It must be something to do with the mobo?
Title: Re: dvd / cd roms not working
Post by: Rik on March 16, 2011, 09:52
I think so, Terry. Either than or the Windows installation is badly screwed.

Catch 22 then..how do you get xp repaired without a cd player  :crazy:
Title: Re: dvd / cd roms not working
Post by: Rik on March 16, 2011, 16:50
USB drive? Use a Linux distro and see if that can pick up the CD drives, if it can, it has to be Windows, if it can't, it's the mobo.
