Ha, you're right, the kernel doesn't see the HP as removable, only the
sony is detected as a removable. (/var/log/dmesg)

Yes.

This is somewhat Alan suggested to me. So I inserted the ioctl(fd,
BLKFLSBUF) directly into the eject code from Jeff Tranter. This works so
far. I have to test it and also your piece of code.
Also I got a feeling on how to send SCSI- commands to a device. (During
this investigations)
I feel now more able to try out things in this direction.

Thanks a lot for all your hints

Andreas
