Check the drive Properties in Device Manager.

Right click on "My computer" Select "Properties".

Go to the "Hardware" tab. select "Device Manager".

Look under "DVD/CD-ROM Drives".

double click on the drive in question and look at the "device status" on the "General" tab.

If it is showing an error code, 10, 39, etc., Uninstall the drive using the button at the top of the device manager.

Then follow these directions for clearing the Upper/Lower Filters: (might want to print this out)

1. Click on Start --> Run --> and type in 'regedit' followed by the enter key
2. Expand the "HKEY_LOCAL_MACHINE" key (looks like a folder) by double clicking it (or clicking the "+" next to it.)
3. Expand the "SYSTEM" Key
4. Expand the "CurrentControlSet" Key
5. Expand the "Control" Key
6. Expand the "Class" Key
7. Please look for a key containing the following string of letters and numbers:
{4D36E965-E325-11CE-BFC1-08002BE10318} (***BE CAREFULL to get the correct one as there are many similarly named strings) the parts highlighted are the parts most likely to be different.
8. High light this key by left clicking once on it
9. On the right hand side you are looking for "UpperFilters" and "LowerFilters" under the "Name" column, once you find these please delete them by right clicking on them and choosing "delete" Note: you may only find one or the other delete it anyway.
10. Please exit the registry by clicking on the "X" in the top right hand corner of the Regedit window.
11. Go back to the "Device manager" highlight "Computer" them click on the "Scan for Hardware Changes" button (Looks like a computer with a magnifying glass across it)
