Anne: This seems OT and probably a bug report or a support request, on
CentOS or at Upstream would be appropriate? This morning, I took two
(2) CD-RW media, one Imation and one Verbatim, and I tried this. Each
of them had four (4) photos on them, a few MB of stuff. No Joy here. I
get different results than you do. When I hoped it would automatically
erase the CD-RW, as it did for you, before writing new data, I got
this Error: The disk is either empty or is not appendable".

When I tried Tools > Erase CD-RW (I tried Erase Fast, Complete and
Last Session and got the same results), I got, "The Erasing process
failed. Do you want to see the debugging output?". Below is that file.
Should a bug or support request be filed about K3b? If so, where? Will
you do that?  I suspect that K3b a very widely used application. I was
logged in as a normal user, not root.   TIA, Lanny
