Yes, the sequence ought to be: sync && umount /dev/<device> || eject /dev/<device> I don't recall if eject includes the previous steps and therefore it is superfluous. I find some applications are reluctant to let go of filesystems on pluggable devices and umount can fail. In this case --lazy option of umount should work: umount -l /dev/<device> -- Regards, Mick
