My Centos5 box has this problem too, but my older Centos didn't, and
and Fedora on my eeepc doesn't. I think it must be a bug in either the
version of k3b in use, or one of its subsidiary tools (no clue which).
What you need to do is: before letting K3B try to erase the dvd/rw is to
manually umount the volume, then k3b will work fine. (as root, type in
"mount", figure out which one is the volume in question, then issue
a "umount <mountpoint>" still as root.)
