[Samba] Maxtor NAS share problem

Actually, it WASN'T root that mounted the share. It was my user account 

Re: NFS, to the best of my knowledge the drive doesn't support it.

And I TRIED using -o uid=1000,gid=100 (the respective user and group IDs 
of "rickj") with the smbmount command (AND the mount command) but the 
ownership still shows as it did below in my example.

Note: On my system "mount" doesn't recognize "-t cifs" and the man page 
on smbfs says the following.

"Mount options for smbfs
        Just like nfs,  the  smbfs  implementation  expects  a  binary 
argument  (a  struct smb_mount_data)  to  the  mount  system  call. 
This argument is constructed by smbmount(8) and the current version of 
mount (2.12) does not know anything about smbfs."

Best Regards,

Rick J.
