title: Impossible to use chown even if I am logged as a root
body: <p>I am currently using debian 6 squeeze. I would like to change the owner of a floder in my usb key.
  So I did :
  <code>chown -R www-data /media/USB/myfolder/myfile</code></p>
  
  <p>I got this message :</p>
  
  <blockquote>
    <p>chown: changing ownership of `/media/USB/myfolder/myfile': Operation not permitted</p>
  </blockquote>
  
  <p>I googled it, indeed my partition is a vfat and then I did :
  <code>vim /etc/fstab</code></p>
  
  <p>Then I add at the end of the file (44 is the uid of www-data):
  <code>default,utf8,umask=077,uid=44,gid=44</code></p>
  
  <p>I rebooted and I got the same error as in the beggining</p>
  
  <p><code>chown: changing ownership of /media/USB/myfolder/myfile': Operation not permitted</code></p>
  
  <p>Then I replaced the line in /etc/fstab by
  <code>default,utf8,umask=077,uid=0,gid=0</code></p>
  
  <p>I got the same problem after rebooting</p>
  
  <p>Can anyone help me,
  Thank you</p>
