I once put a disc in my Sony CD-ROM reader and altered the SCSI
settings at the back.
On booting the machine the CD tray refused to eject, and after a lot
of confusion I half snapped the tray in frustration.
It turned out that there is a jumper on the rear called `Enable' which
is designed for machines to be installed in schools and displays etc.
where it disables the front eject button.
Software eject might have been disabled too, not sure.
:-D :-D :-D
