"The eject is required by some drives -- it forces them to reread the contents of the disc after a burn session has changed those contents. It's a hardware thing, so to fake it you'd need to convince the drive that it's just loaded a new media and needs to perform its initial scan of that new media.

I don't know if this is possible via standard IOCTLs -- I'd expect you'd have to hack the drive firmware (and possibly add your own special IOCTL to the driver code) to do it."

"Power the device down and back up.

find the scsi device id via ""lsscsi -v""
cd /sys/bus/scsi/drivers/sr
echo the scsi id to unbind, then bind.

echo ""1:0:0:0"" > unbind
echo ""1:0:0:0"" > bind"
