Unfortunately this still fails:

$ LANG=C eject -rv /dev/sda
eject: device name is `/dev/sda'
eject: expanded name is `/dev/sda'
eject: `/dev/sda' is not mounted
eject: `/dev/sda' is not a mount point
eject: `/dev/sda' is a multipartition device
eject: trying to eject `/dev/sda' using CD-ROM eject command
eject: CD-ROM eject command failed
eject: unable to eject, last error: Input/output error

with the dmesg output:
Dec 16 11:13:05 localhost kernel: [ 501.616135] Sending
GPCMD_PREVENT_ALLOW_MEDIUM_REMOVAL

One last try might be to ignore the ALLOW_MEDIUM_REMOVAL failure and try with
START_STOP(0x1b) block 1 and 2. This is certainly not the scientific way, but it
would at least be interesting to figure out what is actually required to eject
these beasts.

Thank you!
