eject: using default device `cdrom'
eject: device name is `cdrom'
eject: expanded name is `/dev/cdrom'
eject: `/dev/cdrom' is a link to `/dev/sr0'
eject: `/dev/sr0' is not mounted
eject: `/dev/sr0' is not a mount point
eject: `/dev/sr0' is not a multipartition device
eject: trying to eject `/dev/sr0' using CD-ROM eject command

eject: trying to eject `/dev/sr0' using SCSI commands
eject: SCSI eject succeeded
but... the drive is still inside. The CD is ok, is a working Ubuntu install.

Any idea?
