- A while ago I started having trouble with my optical drives. Both of them keep showing up in Explorer as CD/DVD drives on boot, but as soon as I put a disc in either one, it suddenly turns into a hard-drive—“local disk” is displayed in the Type column, though the File System column remains UDF/CDFS. (I though that maybe it was a permission issue on the registry key in HKLM\System\CurrentControlSet..., but I’m not so certain because of the next test.)
- When I try to open a disc (of any type), I get an access denied error message. If I open an elevated command-prompt, I am able to access the files.
Solution
Access to CD/DVD Drive is Denied through Windows 7 Explorer (Permission Problem) from superuser.com
