Yes, and they burn from the inside to the outside. I can always see
if a disk is used, even without glasses. :-)

I've had cases where I've put a CD-R in for burning, started it,
suddenly changed my mind, and stopped the burner. And then I'm left
with the question as to whether or not the thing is empty. Well,
for me it works to simply remove it, put it back in the tray and
leave it up to either Windows or some program to see what it says.
Win7 AutoPlay will show you what it makes of it.

The limitations of the OPs question ("no third party software"),
prevent me from touting the benefits of third party tools for this
purpose.

Go ahead and recommend some third party software.

You mean like Shadow already did?

Under the Verify mode, the program he suggested reports "Disc is
empty". In two different places.
