root@localhost:~# mount /dev/hdd /mnt/cdrom1
mount: permission denied

I looked at the /mnt directory cdrom1 and cannot change permissions on it. It 
is user=root, group=root. I wanted to change it to group=cdrom.

It used to work fine. I used it for ripping to save my burner the work. I used 
it for playback of audio disks to make sure my burns went well. It's an Antec
