In the control panel, it lists the dvd as a Matshita dvd-ram UJ -851s ATA device. version 6.0.6000.16386. I have tried to update the driver, but it says it is up to date. Is there anything I can do to fix this without bringing it in. The light comes briefly on when I open the door and close it, but nothing happens when I try to use the drive.

    My hp laptop 6100dv does not recognize the cd/dvd drive. I have tried uninstalling and restarting - no good. Drivers are up to date. No idea how it suddenly disappeared/stopped working. Warranty ended last week!!

    Can some one help. It has had very little use. I used it on Sept. 13/08 to download scanner software. Would that have an impact?

My dvd drive is not working, I have Hp pavilion entertainment ntoebook. My OS is window 7, the error code is 10 and it gives the message dvd drive could not start

You can start with this:
if still no go, then re-seat the drive (If removable) then reset the defaults in BIOS.
If still no go, see if you can boot to a bootable CD (Windows or recovery CD usually) if it will not boot, the drive has likely failed

My hp laptop the dv6910us suddenly is not seeing the dvdrw drive which is optical. I can not figure out why

you could try reinstalling the driver, downloaded at the hp support site

and if that dosnt work it might be a dead drive, it will open and spin the cd, but it wont be seen by the computer, thus you might have to buy a new one to replace it or just purchase an external drive

CD Drive stopped working. On device manager it

I think you have Apple's itunes installed on your notebook, just uninstalled it, your CD Drive will work again.

only Microsoft and Apple will solve the conflict.we as an end user keep searching for the solution.

If you don't have itunes installed, then 
Follow these steps: 1. Click Start , type regedit in the Start Search box, and then click regedit in the Programs list. 

 If you are prompted for an administrator password or confirmation, type your password, or click Continue .
2. Locate, and then click the following registry subkey: 
Caution There can be many instances of the registry subkey that is mentioned in step 2. You must make sure that you are in the appropriate registry subkey before modifying the UpperFilters and the LowerFilters values. To verify that you are in the appropriate registry subkey, make sure that the Default data value is DVD/CD-ROM and the Class data value is CDROM.
3. In the right pane, right-click UpperFilters , and then click Delete .
4. Click Yes to confirm the removal of the UpperFilters registry entry.

Hp Dv6205 will not recognize cd

This happens when the CD or DVD reader goes out. This is a common problem with the CD/DVD combo drives. Usually it's the other way around, about 6 out of 10 times the DVD reader goes out. The drive will need to be replaced in order to fix this.
