Re: eject command fails on cdrom
OK there is a link to hdc -
lrwxrwxrwx 1 root root 3 Feb 23 16:48 /dev/cdrom ->hdc
I can mount and unmount the cdrom without any problems, it is just the
eject command that fails.
Running strace eject (when running from /home/riaan) I get the following
output:

Meaning nothing to me...

Again it might as well be greek...
Can anybody else perhaps tell me what it means?
