Hi raj,

You could try uninstalling the device from Device Manager then rebooting your machine. This will force Windows to re-install, hopefully as the correct device. Then try putting in a DVD and see if it has solved the issue.

You will need to delete the upper and lower filter from registry.
steps:
1. Tap Window key (flag key on the keyboard) and R key on the keyboard, at once.
2. You would see the Run window on the screen. Type Regedit in the open field and click OK.
3. Click plus sign (or arrow) next to HKEY_LOCAL_MACHINE
4. Click plus sign (or arrow) next to System
5. Click plus sign (or arrow) next to CurrentControlSet
6. Click plus sign (or arrow) next to Control
7. Click plus sign (or arrow) next to Class
8. In the left hand window pane click {4D36E965-E325-11CE-BFC1-08002BE10318} to select that key
9. In the right hand window pane select the UpperFilters registry key and press the delete key on the keyboard Confirm with an OK
10. In the right hand window pane select the LowerFilters registry key and press the delete key on the keyboard Confirm with an OK
11. Click on the "X" in the upper right hand corner of the Registry Editor window to close it

After that......

12. Open the device manager window Tap (Window key (flag key on the keyboard) and R key on the keyboard, at once) Type in devmgmt.msc
13. Expand DVD/CD-ROM Drives and right click on the device and select uninstall.
14. After uninstalling, plese click on the system icon on the top and select scan for new hardware changes.

The systm will update and will fix the problem. I hope this helps.
This seems to be an issue with iTunes, although I don't know if you have it installed but it should work

Strange, it could have been a missing DLL or something. Keep us informed

Same problem possibly.

My DVD drive is also not working. CDs seem to run fine. When I insert a DVD the drive seems to spin and random and loud speeds and never reads the disc. Not just movies but other types of DVDs as well.
-----------------------------------
Things I have tried:
I deleted the upper fliters. There were not lower filters. Then I uninstalled the driver and restarted. This did not solve my problem.

I tried to update the driver. It said that the driver was up to date. And it did not fix the problem.

I physically removed the drive and put it back. This also did not fix the problem.
---------------------------------------
Attached is a picture of the DVD/CD {4D36E965-E325-11CE-BFC1-08002BE10318} registry. I am wondering if the wrong value is entered in Class? It says CDROM, where one may suspect it should say DVD/CD Rom or something like that.

Also attached is the event ID, from the event that may be related to the problem.

Any help would be very much appreciated.

Thanks.

I have heard of instances on these combo drives that one of the lasers can go bad while the other is fine, sounds like what you have.
