Not in my case it didnt. I had a machine at work today which had these very symptoms, even tried putting another cdrom in. Still no joy. After following the registry fix given on this site, it worked spot on! Great fix, thanks!

I have a DVD (master) and a CDROM (slave) installed on a machine running Win2K pro. About 3 weeks ago the CDROM quit working. I had both icons, device manager recognized both drives, the lights would blink on the drives, but I could not read any type of CD. I figured the CD must be dirty or have an electronics problem. I sprayed compressed air into the drive. Still didn't work. I then replaced the data cable. It still would not read a CD. About two days ago I noticed the DVD quit working. I figured this could possibly be a power supply problem or the onboard controller maybe going bad.

On bootup windows would recognize the drives, but I had no icons for the DVD or CD and the error given by device manager was : "A driver for this device was not required, and has been disabled. (Code 32) "

That didn't make a bit of sense to me so I removed the hardware in device manager and rebooted. Windows says it found new hardware and to reboot again for the change to take effect. After rebooting I still had no icons.

I was about to open the case and check the power supply cables to each drive and needed the pinout info. While researching that on the internet I discovered your site and tried your registry fix. What a blessing. Both drives now work. I was so desperate to keep from reinstalling windows and all my software that I would have settled for just one drive working.

I had been installing and uninstalling some programs lately and feel that was what caused this problem. Thanks for the registry fix info. It saved me a lot of work and frustration.

Hi ya, installed universial usb drive (nusb22e setup for windows 98SE)and this caused some sort of conflict with my in my secondary IDE controller- has yellow exclamation "code 10". My CD-rom/ DVD-rom icon in my computer have disappeared. Tried the safemode delete of all cd-rom dvd-rom refs in device manager and reboot to let windows redetect the devices. Unfortunately no joy. CD-ROM has disappeared from my devices but DVD-ROM is present but has a X over it, and same warning for secondary IDE. The icon is still absent for the drive (D: drive). I did remove all previous usb drives before nusb22e install, and I pretty sure it's the nusb22e drive that's done it. However, I can't remove nusb22e because I don't know where it put all the files and isn't in the add/remove program list. Any help at all would be welcome please. Oh nusb22e works fine as a universial...I just can't access my cd-rom/dvd-rom, bummer. Thanks

EDITOR'S NOTE: Did you try the registry trick mentioned in this article?

Hi, I looked in the registry but in the Windows 98 SE folder: 4D36E965-E325-11CE-BFC1-08002BE10318, there were three entries called CD-ROM. I didn't delete them because they were not the same as the entries in the example above. However after experimenting (disabling both primary and seconday IDEs via the master IDE, rebooting, and then re-enable both IDEs, then reboot). This redetects my CD-rom/DVD-rom drive and the drive icon reappears (ROM works fine). Unfortunately once the computer is rebooted the error message reappears and the drive icon goes missing and there is a cross on the ROM drive in device manager.

The above happens everytime and I end up with the original problem of no DVD/CD-ROM. If I delete the CD-ROM registry entry will that make any difference? Also is it possibly to uninstall CD-Rom driver and reinstall (might be corrupt, but not sure how to do it). Thank you for any help.

Hi. I have a similar problem where I get error 39 on my driver. I have tried your registry fix and this does get my d: working however it slows my machine down and I sometimes have trouble rebooting. When this happens I have to reboot using 'last good configuration' Any suggestions?

EDITOR'S NOTE: I can't see how this would slow down your computer. You must have other problems as well. See for some additional help.

The same thing happened to me. I finally worked it out how to fix the problem.Windows xp System Restore fixes the problem. Go to Start then Programs then Accessories then system tools then system restore.

Restore windows back to the day that your computer was working properly. good luck. It worked for me.

EDITOR'S NOTE: This may work, but it will also wipe out any other system changes you've made since the Restore date, as well as any software installed since then. See

Hello! I had a problem with my laptop DVD-RAM. For several weeks, Windows XP (as well as the BIOS) couldn't detect the drive. Yesterday, it suddenly appeared on my systems devices so immediately searched for ways to install the driver. Removing the device then reinstalling the drivers didn't work. But the registry modification did! I tested a data cd but I kept on getting a I/O device error.

According to a site (I forgot which), changing the settings of the IDE controller would solve it. I modified my Secondary IDE Channel, changing the Transfer mode of Device 0 to PIO Only worked. I was able to read the data CD.

Then I tested a DVD. The explorer stopped responding and the DVD-RAM is nowhere to be seen on the device manager. I inspected the event viewer and I got same message when the disk drive first disappeared. "The device %% disappeared from the system without first being prepared for removal".

Could it be that it's the IDE cables fault? I don't know how to take apart my disk drive. I have a Toshiba Satellite A10 model.

EDITOR'S NOTE: Weird stuff! Try swapping the IDE cable out. You might also want to check for damaged or missing system files. See

If you have Windows XP SP2 and the SONY DVD RW DW-U12A drive... If you get error 39, 38, 29, and/or 28, don't try this, you will have another set of keys in your registry. doesn't support most drivers for it, and doesn't keep updates for it either. The only way you can get the drvers is to pay $20, or illegaly download it. AND: If you got the sony rootkit (a virus) you'll have to un-install it, clean your regisrty, remove infected files, re-install it, and pay $20/download the drivers.

Bob, thank you. This saved me. I have just one question for you...Why did it happen?

EDITOR'S NOTE: Evil Gnomes, most likely.
