Comment 21 for bug 112584

> You should have had two udi

Here the full output with DVD in the drive:

root@pp:/home/ingo# hal-device | egrep " udi|scd0" | grep -B 1 scd0
7: udi = '/org/freedesktop/Hal/devices/storage_model_DVD_RAM_GSA_H30N'
  block.device = '/dev/scd0' (string)
root@pp:/home/ingo#

and I did use the string following '7:udi =' for yesterday's reports.
It does not refer to the volume, but to the type/brand of the drive/recorder. So I followed your further instructions:
All under Feisty (I will try with Gusty after finishing here).
Unfortunately your commands do not work:

root@pp:/home/ingo# /etc/init.d/hal stop
bash: /etc/init.d/hal: No such file or directory

So I searched the filetree for hal and found it under /etc/default:

root@pp:/home/ingo# /etc/default/hal stop
bash: /etc/default/hal: Permission denied

That is absolutely strange that, even as root (with sudo exactly the same) I do not have permission .
So I checked the directory entry for hal:

root@pp:/home/ingo# ls -l /etc/default/ha*
-rw-r--r-- 1 root root 13 2007-03-30 19:52 /etc/default/hal
-rw-r--r-- 1 root root 86 2007-04-10 23:45 /etc/default/halt

So hal is not executable and the content of that file is:

root@pp:/home/ingo# cat /etc/default/hal
DAEMON_OPTS=

So please help further, I do not know what to perform else.
