[Comm] Вытаскивание магнитооптики командой eject от юзера

[Yuri N. Yaschenko]

Доброго времени суток!

Може кто подсказать как заставить работать eject для вытаскивания сказевого 
оптического диска от юзера? Даю от рута команду eject /dev/sda - все 
работает. От юзера eject -v /dev/sda
[yura@ws811-2 yura]$ eject -v /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: trying to eject `/dev/sda' using SCSI commands
eject: SCSI eject failed
eject: trying to eject `/dev/sda' using floppy eject command
eject: floppy eject command failed
eject: trying to eject `/dev/sda' using tape offline command
eject: tape offline command failed
eject: unable to eject, last error: Invalid argument

[yura@ws811-2 yura]$ ls -al /dev/sda
brw-rw----  1 root disk 8, 0 Січ 23 19:55 /dev/sda

Хотя
[yura@ws811-2 yura]$ eject -v /dev/scd0
eject: device name is `/dev/scd0'
eject: expanded name is `/dev/scd0'
eject: `/dev/scd0' is not mounted
eject: `/dev/scd0' is not a mount point
eject: `/dev/scd0' is not a multipartition device
eject: trying to eject `/dev/scd0' using CD-ROM eject command
