You first have to umount the linux partition. I have this uncommented 
in my /etc/rc.shutdown (I have it from the list):

# Insert other shutdown procedures here                
########################################################
#extfs=`eval mount | grep ext2fs | awk '{print $1 }'`
#for _elem in $extfs; do
#       echo -n "Unmounting ext2/ext3 filesystems: "
#       umount -a -t ext2fs
#       echo -n "$_elem "
#done
#
#echo '.'
#exit 0
