Re: /dev/cdrom is not a valid block device
Hi Andreas, David and others
Thanks for your advice.

I reworked the setup as follows;
# ln -s /dev/hdc /dev/cdwriter
# ls -al /dev/ | grep cdrom
lrwxrwxrwx 1 root root 11 2004-01-05 04:04 cdrom -> /dev/
lrwxrwxrwx 1 root root 8 2004-01-05 04:04 cdrom0 -> /dev/hdd
# cat /etc/fstab
/dev/hdd /mnt/cdrom auto ro,user,noauto,exec 0 0
/dev/hdc /mnt/cdwriter auto rw,user,noauto,exec 0 0
Created /mnt/cdrom and /mnt/cdwriter
Now on KDE desktop
I can mount and umount both 'cdrom' and 'cdwriter' by right-clicking their
icons -> mount/umount
But I could not eject them by right-clicking their icons -> eject. I must
push the bottom of their devices manually.
Also on Konsole window
$ eject /mnt/cdrom or
$ eject /mnt/cdwriter
did not work.
Rebooted the PC with the same result
