Hi, I have a compaq presario 5000 and I recently discovered that I am unable to see either the DVD-rom or the CDR-rw drives any longer. They were working not that long ago. Now, they don't even show up in any hardware lists. I load a cd into the DVD drive and it doesn't do anything. The other drive (CDR-rw) is even in a worse state. It doesn't even open the door when you press the open/close button. I'm not sure what happened to these all of a sudden. Does anyone have any ideas? Any help is appreciated. Thanks!

Have you made any hardware or software changes around the time the problem started occuring?

Do your BIOS and/or start-up messages show any mention of either drive?

If it's a hardware fault, you might be able to narrow down the culprit by doing the following (pay attention to Master/Slave jumper settings on the drives!):

1. Remove the DVD from the system; see if the CD drive is then at least recognized by the system. If not:

2. Remove the CD and install the DVD by itself.

3. Install each device (one at a time) on the other IDE channel.

Although I've never seen this happen so severely that the devices don't even appear in Device Manager, there is a possibly related software conflict caused by some CD/DVD burning programs (Roxio is one). Read more about it here:

In the above articles, mention is made of changes to the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\ branch of the Registry. Be aware that the changes may also have to be duplicated in the ControlSet001, ControlSet002, etc. branches as well.
