Yesterday I put Windows 2000 driver CD into my CD-Rom drive and suddenly my laptop doesn't "see" that drive anymore.
When I go to system/hardware, it's telling me that I'm having a Device Manager Error Code 19 and that my registry might be corrupted. I found this information that may possibly fix this problem for me, BUT I have no idea what an upperfilter or lowerfilter is. Can anyone help me shed some light on this??
~~~~~~~~~~~~~~~
Remove the Upperfilters and Lowerfilters values completely from the following registry key:
Start, Run, Regedit, find key, select key, expand it. then delete the to sub keys listed. I have no idea what they mean. I ran into the same problem after adding a BackPack-CDR to my system.
Good Luck

Hey,
i have the same problem. what are the upper and lower filters? do I need to un install and reinstallm y CD roms after, or do they automatically repair?
Sorry i dont know what they are either but if you follow the instructions above and just delete the filters your comp with recognise your cd drive again without any re-installing od drivers,(at least i didnt need to re-install any, i am running windows 2000 pro on a dell laptop)
first of all thanks for replying. I have two computers, my newer one has upper and lower filters, but my older P2 doesnt. Im going to try to blow away the whole reg file sub-keys and try to re-install. unless you have another idea
thanks
