I have a system here running windows xp home sp2. It has two optical drives..... Liteon cdrom ltn527t and a liteon cdrw sohr5238s both of which are listed in device manager but with yellow question marks. Both drives work on a dos level and both will boot. however neither is listed or working in windows. I tried this fix from microsoft:

http://support.micro...124120121120120

but that did not fix things.... One difference too is that this conputer has controlset01, controlset02 and controlset03 where the article only mentions controlset.... The settings it mentions are in controlset01 but not in either of the others. I have tried both methods listed and neither one fixes the problem.

I remember reading about this problem before but now cannot find it.

Have you tried deleting the drive through device manager?

Can you check to see if you can boot from your cd-rom drive to make sure it's working at all. Do this by placing your Windows installation CD into the cd-rom drive and reboot. Your computer should give you a prompt that says press any key to start setup I believe.

If that works then you can rule out that it isn't the cd-rom is physically going bad. On the other hand if it doesn't boot then you will possibly know that the drive has gone bad.

thank you for your reply however I have already removed them from the device manager and had already tried using them in dos and by booting from them as said in my original post. However I went back into the registry and edited the 3 control sets in turn and that seems to have finally solved the problem....Not sure why this conputer has 3 control sets ( number 01 -03 ) but it does....
