A common issue between Microsoft Windows and Norton Security products is that during updates to Norton products or the removal of Norton products is that the registry entries for the disk drives becomes corrupt. To resolve this issue you must open the registry by pressing the windows key on your keyboard and the letter R key together then type regedit into the run field and click "ok"

Once into the registry navigate to the following key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}

Now in the right hand pane select the following:

Upper Filters
Lower Filters
Upper Filters.bak
Lower Filters.bak

and delete the entries.

Once you have deleted the above entries reboot the computer and your disc drive should be working.
