OS 10.12.6

I loaded a DVD into my Lacie external drive but it does not show on the desktop. I checked the preferences in the finder and the appropriate boxes are ticked. I ran first aid but to no avail. I ejected the DVD couple of times to see if that made a difference but it's still not showing. I'm sure the drive is not defective. What to do now?
