[Tfug] permission denied

[arcturus]

I'm getting a 'permission denied' error when trying to copy files of any 
type from my linux ftp server (abit) to a mounted FAT32 partition over 
the network (Albatron).  

root at abit:/home/ftp# cp tu1.avi /home/ftpdown/Albatron/
cp: cannot create regular file `/home/ftpdown/Albatron/tu1.avi': 
Permission denied

Any ideas what the problem might be?
