CDROM Detection Problems

Hewlett-packard / Hp pavilion dv6500 notebo...

Specs: Microsoft Windows Vista Home Premium, 1.8 GHz / 958 MB
At my wits end now.
Had this problem for some time now but only tried to fix it these last few days.
My cdrom suddently stopped working ages ago and i thought it was maybe a software conflict. So after finally rebooting system back to factory condition i thought this would fix problem but it didnt.
Device does not show up in device manager but powers up ok and ejects no problem. I thought that maybe the drive itself was faulty so i tested it on my friends laptop who has same as me and the drive works perfect.
So i thought maybe motherboard isnt doing so well since i have read the hp dv6500 series has problems with dodgy motherboards.
Then suddenly today drive popped up and worked fine while i was updating windows.
Had to reboot after update and now drive has gone again??

I have tried this delete upper lower filters in the registry but they dont exist there so thats not the problem.

I have following setup,
Manufacturer: Hewlett-packard
Model: Hp pavilion dv6500 notebook pc
OS: Microsoft Windows Vista Home Premium
CPU/Ram: 1.8 GHz / 958 MB
Video Card: NVIDIA GeForce 7150M / nForce 630M
Sound Card: Conexant High Definition SmartAudio HD2

Everything else works perfect but im lost as to what to do now?

Any suggestions

Not sure I understand exactly what you are saying. The filters are located in the registry. What do you mean you tried this delete thing.

Hi, I have checked out my error and keep finding the following remedy that did'nt work for me.

This happened to me and i called a dell support guy and he fixed it!!!
This is what you do...
Start the Run Command Prompt
Type in "regedit" without the parrenthesis then click ok
Then find {4D36E965-E325-11CE-BFC1-08002BE10318}
The whole thing looks like this:

Then delete the upper and lower filters....

Thats what i meant with filters.
I checked my registry but those filters are not there.

HI , Yep tried that but to no avail:(

Just says cd/dvd drive is not detected.
Mentioned I could forward error report to microsoft but it would cost £46.

Just a strange error this. The drive works fine.
Today it popped up while i was working on something and i was able to use the drive but after i rebooted due to update it didnt come back. but power is still running fine through drive. load a disk into it and it lights up, spins and checks the disk but nothing appears in my computer or device manager

Well, the glitches that come up every once in a while(sporatic) can be a real bear to diagnose, and very hard to nail down, good luck.

Something else to try.
This goes one step further than the first fix.

again no joy but thanks for help so far.

As it happens cdrom popped up again today briefly. didnt reboot this time and after five minutes or so away it went again:(

Managed to check hardware setting etc for any conflicts but all reported as Ok.

Never had this problem before, Its very strange....

Interesting to me, so I did some googling. The net is full of people with literally the same problem. All you have to do is google(cd/dvd rom missing/undetected in vista). Seems like some have linked vista updates with the missing/undetected roms. Some say the vista updates may contain driver updates which are having problems with certain cd/dvd roms(ie installing the vista updates with the new drivers they contain may have a conflict with the rom installed. I found no absolute fix. Try a little of this, or a little of that. Sounds like a can of worms to me.
