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.
