Toady I downloaded a .iso file and wanted to burn it to a CD.  I started K3B
as usual and while it was loading (takes a while from gnome), I got out a
blank CD and went to insert it in the drive.  I got no response to the open
button on the drive and tried a number of things (see below) before opening
my system log and finding:

Just for grins I rebooted the system and then everything was fine.  Anyone
have a clue what actually went wrong here?  I mean maybe it had to do with
me trying to open the drive at the wrong time during K3b startup (as I often
do).  I just do not know.

BTW, the other things I tried included more open drawer button presses and
using the $30 tool (a paper clip) to open the drawer, close it, open it,
inserted a blank, closed the drawer and when the system never saw the CD and
the drawer open drawer never did work  I realize this makes sense if the
kernel had disabled the drive but wanted to describe them in case anyone
wanted to suggest trying such things
