That didn't work;

"
bretnewworkstation:~# chmod u=rwx,g=rwx,o=rwx /data
bretnewworkstation:~# ls -l /data
total 16
drwx------ 2 root root 16384 2009-04-02 17:34 lost+found

"

bretnewworkstation:~# chmod ugo=rwx /data
bretnewworkstation:~# ls -l /data
total 16
drwx------ 2 root root 16384 2009-04-02 17:34 lost+found
"

That also didn't work.
