Hello,
I have a hp dv9000 series laptop. I recently installed Windows 7. After installing my dvd/rom is not detected in device manager or under the "my computer" listing. Under the device manager I clicked on the "show all devices" tab andd still no dvd/rom. I did install some free dvd buring software called "Phantom". This DID detect my "e" drive under device manager and my computer.
In the device manager it said i was missing a coprocessor driver. In the my computer it would not recognize that I had a disc and would ask me to insert one. Seeing that this "phantom" software was getting me nowhere I uninstalled it. I have installed drivers. my video card is Nividia nforce 560 series. I have looked on the hp website and discovered that this product series will not be supported by HP for the DV9000 series.
Mechanically the drive does work!
Drivers have been updated, uninstalled, blah blah blah! This appears to be a common problem but after searching the 'net for hours and trying various suggestions there has been no cure - YET! I installed the Windows 7 Ultimate from Vista.
The 411 for my laptop are as follows: HP dv 9728, AMD Turion 64 x 2, NVIDIA nForce 560, DDR2 RAM.

Things to try:

1. Uninstall the drive through Device Manager.
Restart computer. The drive will be automatically reinstalled.
or...
2. Delete Upper & Lower Filters http://support.microsoft.com/kb/982116
Restart computer.
or...
3. Download, and run Restore Missing CD Drive patch
Double click on cdgone.zip to unzip it.
Right click on cdgone.reg, click Merge.
Accept registry merge.
Restart computer.
or...
4. Go to Device Manager, click a "+" sign next to IDE ATA/ATAPI Controllers.
You'll see two items:
- ATA Channel0 (or Primary Channel)
- ATA Channel1 (or Secondary Channel)
Right click on each of them, and click Uninstall. Confirm.
Restart Windows. They'll be automatically reinstalled.

Allan,
I did what you recommended and a few extras. I did not run the cdgone.zip. the "read me" file said that that zip folder was last updated in 2001 so I wanted to double check w/ you first to make sure that was safe to run.
Also went to NVIDIA for coprocessor updates for the mo/bo. there was one for audio but NVIDIA would not let me install it.

It's okay to run the file. Either it will help or it won't - it won't hurt anything.

I ran the suggested program and still nothing. If I had the money one of the first things I would have bought a new dvd rom first and then worked my way backwards. If you have any more ideas I'm willing to try it.

Please try two things:

1) Boot to safe mode - does the device show up?

2) Make sure the optical drive is the first device in the bios boot order. Then insert a BOOTABLE disc and reboot. Does the system see the drive at boot?

Hello Allan,
I have ran the laptop in safe mode and have also changed the boot order w/ the disc being first and still nothing! My next test will be to by a new dvd/rom. I have tried almost everything that has been recommended and still nothing. *sigh*

Yep. If you can't boot to it, it probably needs to be replaced.
