Windows 7: DVD drive disappeared after Win 7 install

I know how to use arrows / tab keys but seriously, if I pressed the down arrow on that screen you posted it would skip the whole screen and go to Diagnostics which you cannot see off that shot. The other entries are static, non editable. I can't really say it any more times. This is not a good BIOS!! I've searched google and others complain about the lack of functionality in some laptops BIOS. Guess I struck out with this laptop.

If I can't edit the BIOS, which I can't, then my DVD drive is doomed?

Seriously, I was an IT Manager for 5 years, I was good at my job.

But this disappearing DVD drive has got me stuck. It seems to work (opens and spins a disc), but there's nothing I can do to make Windows recognise it in any shape or form.

Reseating it, registry hacks, BIOS upgrades and so on.

It was fine until I put Windows 7 on.

Maybe it's an excuse to get a new laptop.

Thanks for all the help anyway.
I apologise Barney, I did not read thouroughly, I meant no disrespect as to your abilities. I will consult with the forum elders on this one.
Don't give up!

Vista / Windows 7

No need to apologise, really. I am just very frustrated with it, it was working fine before Windows 7, and everything still points to a physically working drive (light, spinning etc).

It's annoying going round in circles and not getting anywhere. I can't think of anything else to do now, might be some in depth registry thing but who knows. I do appreciate the help.

P.S. Barney is my dog's name, I am Sarah

I think that may be too optimistic. Just because the drive's internal mechanisms pick up on the presence of a disc and spin up, doesn't necessarily mean the hardware is intact. In fact, I'm pretty sure you can completely disconnect your average IDE CDrom/DVD drive from its controller, and it'll still spin up in the presence of a disc as long as its molex (power) connector is plugged in.

My gut feeling is that the hardware is broken and the timeline link to the Win7 installation was coincidental (perhaps that bit of ex3rcise was the last straw!). If you've tried two separate drives, it's presumably the controller or related motherboard circuitry which is misbehaving, if the problem is indeed to be found at the hardware layer. I'd suggest:

1) Try booting off a bootable CD. Make absolutely sure it's bootable (on other machines). Since the current boot order places it ahead of the HDD (from your JPGs), that should in theory help to rule out any Windows/registry/software issues. If the drive fails to boot off a known-good bootable disc, it's bung.

2) Try flashing the BIOS to the latest version, if there are any later versions. I doubt it'll help, but it's just about the only other thing you can do before the soldering iron has to come out.

Sorry if any/all of these suggestions have been discussed already. My toddler is making it difficult for me to pay attention right now

XP, Vista, W7 64bit Home Premium

Try the latest Nforce Chipset drivers would be my only other suggestion - I know its to do with the storage manager, as it effects the dvd drive - thats with intel chipsets though, but would probably be the same or similar with nforce chipset - windows will load the driver (if AHCI is enabled in the bios prior to OS installation), but with intel it also needs the matrix driver software to function properly, and can make the dvd drive non functional or dissappear if not installed.
I hope this is the right suggestion as i saw the at the hpsite either intel or nforce chipset drivers available and assume the nforce chipset supports AMD cpu's - you could also send support at an inquiry about the drive dissappearing if nothing else works.

win 7 x64

I've found advice to disable the drivers integrity check: Run: bcdedit /set loadoptions DDISABLE_INTEGRITY_CHECKS.

this worked for me.

Windows 7 Home Premium

I have the EXACT problem.

Same model of PC also! - I've tried swapping my optical drive with that of another dv6500. Resulted in recognition of that drive. I swapped them back and my own optical drive was newly recognized and drivers were installed with it. I was able to boot DVDs from the drive and all worked well. The following morning however it again disappeared!

Windows 7

Same problem here...

My dvd drive was perfect before installing Win7.. I had winXP, then W7 7100 RC, then W7 7600 RTM. My dvd drive worked fine within the first installation of W7 RC and during the next 2 month... then seemed to be broken or something because it disappeared from the file manager and from the system devices list... but, of course, was phsically ok because of the light and the spinning.
The problem is that it was not a defined issue, because sometimes the computer started with the dvd drive recognized just for a couple of minutes and then disapeared. This permitted me to look for a "lucky boot-up" (where the computer recognize the dvd drive) to try and reinstall the newer version of Win7 (7600).
I did it and the new configuration worked for a couple of hours. Then the dvd drive disappeared again.

I tryed the Upper/lower filters fix: useless.
I tryed the drivers integrity control fix: useless
I tryed to flash the bios of my pc wit the newest version: still useless

I have an Acer aspire 5520g with a 2 core AMD processor.
When Sarah said " I found this info in the registry: MAT****A DVD-RAM UJ-861H ATA Device" i figured out that UJ-861H is the same name if my dvd hard drive. Could it mean something?

I'm getting crazy like Sarah with this problem, I don't really think it is only a coincidence with the broke of the drive..

Any help will be appreciated, sorry for my english misstakes, I'm doing my best.

Originally 64-bit Windows Vista - Installed Windows 7 Ultimate
Same problem; there is no solution currently available!

FYI, similar to the original poster, I have an HP Pavilion dv7-1129wm Entertainment Notebook PC -17" BrightView Widescreen LCD,2.1 GHz Dual-Core Processor, 4 GB Memory, 250 GB Hard Drive, SuperMulti DVD burner,DVD+/-RW, 802.11b/g wireless LAN, Webcam, and Windows Vista Home Premium 64-bit.

I have the EXACT same problem too! My HP laptop that came with Vista was PERFECT prior to installing Windows 7 Ultimate. A few days after upgrading, my optical drive downright disappears despite the eject button on the optical drive working as it should and the drive light coming on and spinning discs that I put in. After following all instructions in this thread, no change. It is GONE. My optical has DISAPPEARED as a result of installing Windows 7. This is NOT a hardware failure with coincidental timing, as there are clearly many others who have experienced the same thing.

I've also tried downloading patches/updates from Microsoft and HP, but when I run them, they tell me the patch/update doesn't apply to my system.

I am going to reset my computer back to factory settings as saved in my partitioned hard drive. Hopefully my optical drive will not still be vanished from existence after I revert...

Vista / Windows 7


I had given this thread up for dead. I still have no joy at all and it's not until your drive is gone that you realise how much you need it.

If anyone else comes up with any solutions please post!!

I'm feeling the pain!
