Hello. I am on Windows XP on a Sony VAIO laptop and I rushed into a weird problem. Suddenly my CD-ROM [it is a DVD/CD-RW] device stopped from functioning normally. It is installed ok, drivers are ok, Windows know this CD-ROM and tells me CD-ROM is ok, no any problem. But, no matter what CD I insert whether DVD, Audio CD, Soft CD or just CD recorded by me Windows doesn’t do anything, not even recognizes that a CD unit was inserted. CD doesn’t autostart, but the worst is the Windows doesn’t even fill that a CD containing data was inserted, so, if I open CD-ROM manually it is empty. I assume there is a problem in the registry only; at least I hope it is so. So, if there is a way to change something there to fix the problem, I would be vary glad to know that I want to watch my good DVDs, :-( Thank you. The beat never fades!

I don't know why you assume this is registry problem, sounds more to me like the drive has gone faulty. If you have an XP install CD, or any other known working boot CD, then set your BIOS to boot from CD and see if it works. If not it pretty well confirms a fault with the drive.

See my post on message #118088, for registry fix for cd. Please post back within 24 hours or I will delete the post from my follow up list. Thanks.

If you are familiar with editing the registry try this. Open regedit and look for; HKEY_LOCAL MACHINE\CurrentControlSet\controlClass Key name{4D36E965-E325-1CE-BFC1-08002BE10318} Value Data: Delete all Value data from Upper Filters and Lower Filters Note: Do not delete the key or multi-string values. Delete only the data values. Exit and reboot BACKUP BEFORE ANY DELETE. Please post back within 24 hours or I will delete the post from my follow up list. Thanks.
