Did you erase the disc?

1) I strongly recommend using K3B or some other more robust GUI app
for CD/DVD management.

2) That said, I have never been able to erase a rewritable disc with
K3B.  It always errors out because it claims the disc is in use (well,
yeah, it's mounted!).  The last time this happened (a few days ago), I
extracted the erasure command from K3B's log and created a shell
script to do the job, complete with umount.  That works just fine.
(I'm open to K3B suggestions that would be more convenient here -
hint, hint.... :-)

3) Also, the last time I tried to do a multi-session continuation with
K3B I hit enough snags to give up.  Actually, that was when I ran into
the erase problem above, but at least that part is solved.
