Some questions on use of CD-ROMs



Hi, some question:

1) How to read from command line the label of cd-rom (IDE/SCSI)
   inserted into device?

2) How to eject the cd-rom simply press the eject button of device when:
    o the cd-rom is mounted.
    o the cd-rom is mounted and the users use the files on it.

3) I have 7 cdrom SCSI connecto to channel 2 of a SCSI adapter on a system
   whit kernel 2.4.18-27.8.0 and when I mount and use the cd-rom I
   get in /var/log/message the attached error: what means?

Thanks for your reply...
