Laptop does not detect dvd drive

[usagi1009]

Hello,
I have an HP Pavillion dv9000. It is not detecting the dvd drive. I already tried HP and their "fix it" suggestion did not help. I was wondering if anyone knows how to fix this.
Thank you

Hello and welcome to Tom's Hardware Forums.

This might be the old "upper and lower filters" problem that rears its ugly head from time to time and if it is, this Microsoft KB might help you. If it doesn't, it will have no no other harm to the system so try it first and let us know how you get on.
