In windows 7, if you are facing the optical drives not detected/ not found problem even if it is visible in BIOS and using the standard driver, then you can try out the following options. The standard solution that worked in my desktop is as follows:
- Press Win key and type regedit.exe, a new window- Registry Editor will open
- After that, navigate to the following path from the left pane:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325- 11CE-BFC1-08002BE10318}
- Then, delete both UpperFilters and LowerFilters in the right-hand pane (UpperFilters.bak and LowerFilters.bak entries can be ignored).
- Exit from the Registry Editor, and Restart your computer, you'll find problem solved!!!
The following is the image shown after deleting the filters as indicated above:
