Question : CD/DVD drive not found after reboot (CODE 41), replaced with a spare drive and getting same error

Having a problem since a recent reboot.

(Windows XP SP2
Athlon XP 2200+
512Mb RAM)

I had just installed new drivers for ATI Radeon, and rebooted the PC.
After the reboot, the shortcuts to the CD/DVD drive can't find it, and the drive has disappeared from the My Computer list.

In Device Manager, the yellow exclaimation marks are showing on the device name, and in the properties box the Device Status says :

"Windows successfully loaded the device driver for this hardware but cannot find the hardware device. (Code 41)"


I opened up the case, took the connecters out, plugged them back in, turned the PC back on (also checked the BIOS to see if the drive is being recognised there - and, yes it is). same problem.

I opened up the case again and tried the drive on the other position on the IDE cable, still got the same error.

Finally, i swapped the drive with an older CD/DVD ROM drive (which, to my knowledge, is still in fine working condition), and booted up the PC.

I am still having the same problem. When Windows starts up, the status balloon pops up informing me of the new hardware attached, then this disappears and I am left with the same problem, Device Staus Code 41. I have installed drivers for this older drive as well, they installed and I was asked to reboot, after which the drive would be recognised and ready for use, which didn't happen.

This is an urgent problem, as I require a DVD drive for installing software.

(The original drive is a Medion MD 42064 [Pioneer DVD RW DVR-107D], and the replacement drive is a Toshiba DVD ROM SD-R1102)

By the way, the reason I'm asking in the XP rather than the Hardware area is because I'm now thinking that both of the drives actually work and that the problem lies outwith the hardware.

Thanks in advance.

Answer : CD/DVD drive not found after reboot (CODE 41), replaced with a spare drive and getting same error

This fix requires editing the register. if you dont feel confident messing with it, i would suggest you dont. Can screw it up if not done properly. With that said, below are the steps to take:

-Click Start button
-Click Run
-Type "Regedit" without the quotes
-Locate the "HKEY_LOCAL_MACHINE" node
-Followed by the "SYSTEM" node
-Followed by the "CurrentControlSet" node
-Followed by the "Control" node
-Followed by the "Class" node
-Locate & Click on "{4D36E965-E325-11CE-BFC1-08002BE10318}"

to the right panel look for the 'UpperFilters' and 'LowerFilters' keys.. and delete them.
Note: sometimes both are not there.. it can be one or the other. In either case delete any instances of it.
Windows upon reboot, will recreate those files fresh.

REBOOT YOUR MACHINE

hope this helps!
