Hi
The reason you see all the permissions of /dev/cdrom set as "read-write for all" is that /dev/cdrom is a symbolic link pointing to /dev/hdb. So, as to say it, a symlink does not have permissions. The permissions you set are those of the thing that symlink points to. In this case, /dev/hdb. Normally, the permissions of it should be 660. Most probably the permissions for your /dev/hdb WERE 660 -and this is why you weren't able to access the Cd drive as user-. This means root and anyone in the proper group should have permissions to mess with it. If you are in a secure environment you should give you (and your club members e.g. girlfriend

), access to the proper group so non-club-members (e.g your girlfriend's little sister) should be left outside

. But in a domestic environment it's just better to chmod it 666. This means that everyone has access to /dev/hdb. (or whatever device your optical drive is).
