Cannot see CD drives

  Peter Lanky 16:13 01 Apr 2010

PC has 2 CD drives, and suddenly I can't see either of them in My Computer or Device Manager in Control Panel. Checked all leads etc. Power is OK as the drives open and close normally. Tried uninstalling all IDE controllers and letting them reinstall.

Using Windows 7 Home Premium.

Any suggestions as to what to try next?

Try this if the optical drives are not appearing in My Computer or Device Manager.
(This is sometimes caused by the removal of Roxio or other writing software.)

Run regedit and navigate to registry key

Highlight it and in the right pane, find the Upperfilters and Lowerfilters values.
Highlight each one in turn, right click and delete them.
Close regedit and restart the computer.
If in doubt make a restore point before making changes.

None of these worked (there were no upper and lower filters in the registry key anyway). I tried the physical method and unplugged all the cables and plugged them in again, and lo and behold it worked.

However, the information will be stored in my head for future use, you thanks for the tutorial.
