rsync - Jul 2004 - filesystem is full ??

Hi All,
I try to test rsync on my notebook with Freebsd 5.2
I mount a dir to a win2000 hd  with 80 gb free space as the BACKUPDIR
after I run a script  there are 3 files named

dev-ad0s1a.0.200406290920.dump.gz
dev-ad0s1e.0.200406290920.dump.gz
dev-ad0s1g.0.200406290920.dump.gz

end up with filesystem is full..

df show me  enough space on local disc

if I run the script again I get the error after 1-2 minute
 
can anyone help me 
tia
