If you are having troubles with your optical drives not being recognized in Windows 7, here is the solution that worked for me.
Uninstalling/Reinstalling over and over didn’t do anything through device manager. Disk manager was just as useless.
The problem was with the upper and lower filters in the registry.
Here is the solution: http://windows7news.com/2009/01/15/windows-7-not-recognizing-dvd-drive/
Just in case that link ever goes bad, here is the process, quoted:
- Press Windows R, type regedit and press enter.
- Open the Registry key
- In the right pane, right-click UpperFilters, and then click Delete.
- Click Yes to confirm the removal of the UpperFilters registry entry.
- In the right pane, right-click LowerFilters, and then click Delete.
- Click Yes to confirm the removal of the LowerFilters registry entry.
- Exit Registry Editor, and then restart the computer.
Note After you remove the UpperFilters registry entry and the LowerFilters registry entry, you may lose functionality in certain programs such as CD recording programs. In this scenario, you must reinstall any affected programs. If the problem recurs, contact the program vendor to determine whether an update is available for the program.
Click on Start -> All Programs -> Accessories -> Right click Command Prompt -> Run as administrator.
Paste the following line and hit enter afterwards
<code>bcdedit /set loadoptions DDISABLE_INTEGRITY_CHECKS</code>
This should solve the problem of DVD drives not being recognized in Windows 7.
