Hello
I am attempting to change the ownership of and permissions for the 
contents of a USB Seagate Free Agent drive. At present, root has 
ownership, although everybody and their dog can rwx files:
   $ ls -l /media/FreeAgent\ Drive/
   total 24
   drwxrwxrwx 1 root root     0 2007-11-27 20:28 BAKUPS
   drwxrwxrwx 1 root root     0 2007-11-19 20:39 DVD
   drwxrwxrwx 1 root root 24576 2008-02-16 15:50 MUZAK
   drwxrwxrwx 1 root root     0 2007-11-04 00:04 System Volume 
Information
As root (actually, both attempted as root via su as well as via 
sudo), I have attempted:
   chown andy /media/FreeAgent\ Drive/ -R
as well as
   chmod -R og-rwx /media/FreeAgent\ Drive/
and
   chmod -R u+rw /media/FreeAgent\ Drive/
Unfortunately, the output of ls -l /media/FreeAgent\ Drive/ remains
   total 24
   drwxrwxrwx 1 root root     0 2007-11-27 20:28 BAKUPS
   drwxrwxrwx 1 root root     0 2007-11-19 20:39 DVD
   drwxrwxrwx 1 root root 24576 2008-02-16 15:50 MUZAK
   drwxrwxrwx 1 root root     0 2007-11-04 00:04 System Volume 
Information
This doesn't interfere with my playing the music listed under MUZAK 
as andy, nor adding to the files. But, it does not change the 
description of the permissions related to those files.
Can someone explain what's going on here please?
