Gary, I've watched for this to go awhile before i went and jumped in, to 
ask my question ... it's about my cdrom drive, whic is a sony, one 
that's been 100% reliable for me, I used it regularly under linux with 
k3b to burn stuff.  Now, under FreeBSD, k3b won't even recognize it as a 
ro or rw cd drive at all.  I can coax burncd to burn bootable disks 
successfully with it, but after the command completes, all further 
accesses to the drive return "device busy", and I have to reboot FreeBSD 
in order to even eject the cd.  The only way I even knew the disk was ok 
was because afterwards, it tried to boot the machine from the disk image 
of a FreeBSD boot disk (which is what I was burning, for a different 
machine, an AMD64 next to it).  Lucky that this machine is even binarily 
compatible (the Intel box is a 64 bit processor, so it boots AMD64 fine, 
but I didn't install it that way).

Anyhow, how could I either coax k3b to recognize it, or get burncd to 
let the disk go after it's finished with it?
