Yep, the eject and close commands do work. No problems at all. The
inquiry command led to a 'misbehaving' drive. If I issue inquiry the
drive makes some strange noises, almost like on power-on. Maybe there is
some SCSI bus reset going on? That's the same effect when using cd-info
or mplayer with libcdio on the drive.
@idle command: I don't know, how can I find this out without using
mmc-tool? Can hdparm possibly issue such a command? I also know sdparm
but is seems a bit complex for me (who has no SCSI device programming
knowledge).
@manual: At least there is nothing in the original manual that was
shipped with the drive. And I can't find any detailed technical infos on
the net. I have found some information about the drive in the Feurio!
drive DB. I've sent the Feurio team a mail asking for help, maybe they
reply maybe not.
I'm going to install cdrdao and cdrecord and do some checking with them.
Also going to check the speed setting commands from mmc-tool.
@example: I really don't know what to change there to make the drive
behave correctly. Probably related to my SCSI knowledge lack :D
