DVD Drive not recognized in HP DV9620 laptop

Specs: Windows 7 Ultimate 64Bit, AMD Athlon 64 X2 Dual Core TK-55 1.8 GHz / 2 Gb
This is not the first post about this kind of topic and probably not the last. I read most of the other threads but didn't get much further.

On my laptop I had Vista installed and suddenly my DVD drive was no longer recognized in the Explorer. A DVD/CD will load fine in the tray and you can hear the disk being rotated, but then it stops and nothing happens. The tray opens and closes fine.

I remembered having uninstalled Nero after it stopped working for some reason so I figured this could be the reason. I tried some suggestions I found in other threads concerning problems with Nero. To no avail.

I resorted to format C and get rid of Vista (32Bit) (finally). Win 7 (64Bit) is now installed but there is no difference, the drive is still not recognized. I had to install Win 7 from a USB as the DVD drive can not be used for booting.

I use the DVD writer quite often as I need to back up a lot and create DVD's. The drive has also Lightscribe.

I am not aware that there are specific drivers from HP for the drive, other than a program for the Lightscribe function. But drivers or not, Windows should at least recognize the drive. It is also not in the Device Manager.

Anybody who has any idea in what direction to look, many thanks if you could answer in this thread.

There are some ?'s in the Device Manager under the tab Other Devices, it displays a couple of Base System Devices (Location: PCI bus 2, device 5, function 3 / PCI bus 2, device 5, function 2).
Drivers for them can not be updated.
There is also an Unknown Device (Location: on Microsoft ACPI-Compliant System). Same thing.

Also, in the Device Manager there are under the tab IDE ATA/ATAPI Controllers, 2x ATA Channel 0 and 2x ATA Channel 1
One Channel 0 says its Device Type is ATA Disk and that its current mode is Ultra DMA Mode 6
The rest doesn't seem to be doing anything.

if u can't boot from optical drive then the drive is bad. It's possible for a bios to recognize a faulty drive. Most of the laptop optical drive can be removed, try to re-install it may be it's a connection issue. If it doesn't help replace the drive.
