Woke up this morning and my Win7 PC couldn't see the bluray drive.
Went through all the usual suspects (loose connection, uninstall/scan for changes in device manager, safe mode, disabling AV, cursing, praying, more cursing) but I couldn't get it to show up (Windows would always fail on trying to install the driver). Finally, I figured it out. Turns out that when I uninstalled a virtual drive program that I added to install an ISO, the removal didn't complete as successfully as the uninstaller let on...
To Fix
- Open up Regedit
 - Expand to: [HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318]
 - Delete the "LowerFilters" value. You might also have to delete the "UpperFilters" value, I didn't.
 - Restart
 - Burst into tears of joy
