Many apologies!

hinata:/home/piers# addgroup piers cdrom
The user `piers' is already a member of `cdrom'.
hinata:/home/piers# ls -l /misc/cd
total 4
dr-xr-xr-x  1 root root 2048 2004-09-08 06:30 audio_ts
dr-xr-xr-x  1 root root 2048 2004-09-08 08:12 video_ts
hinata:/home/piers# cd /misc/
hinata:/misc# ls -l
total 2
dr-xr-xr-x  1 root root 2048 2004-09-08 06:30 cd

So the problem here seems to be that the directory is part of the 'root' 
group, not the 'cdrom' group.  If I unmount the CD drive, the /misc/cd 
directory vanishes.  I checked my email server and it has the CD drive 
in /media/cdrom and is owned by root and group is set to root.

How can I fix this problem please?

Thank you very much for your help again.

Cheers - Piers
