DVD drives not visible under 'This PC'

There is a category for 'Hard Disk Drives' under 'This PC.' And also a category for 'Devices with Removable Storage.'

However, my two DVD drives do not display under 'This PC.' I'm sure there is a switch setting somewhere?

Thanks.

Try turning on Preferences / Folders / Virtual Folders / Native display of 'Computer' / Show empty disk drives.

Thank you. That was the switch.
