OK. I've made  some tests and if you believe that anything I ran into
warrants a bug  or support request against K3b, on CentOS.org and/or
RedHat.com please tell me.

I opened a terminal window, "su -"  and then "umount /dev/hdd" and
then I exited from the shell.

(a) I can use the drop down menu, "Tools" > "Erase CD-RW", without any problem.

(b) I can write new files to the CD-RW. I did not get a message,
asking me if I wanted it to erase the CD-RW media. It did *not* erase
the existing files on the CD-RW media, before writing the new files.
It added the new files, as if the CD-RW were a multi session disk.

(c) In the K3b list of files in my home directory (/home/lanny) it
showed files that had been deleted previously.
