Modify the while statement to something like ...
    while read i
    do
            if test -d "${i}"
            then
                    data=`du -sh "${i}"`
                    echo "${data}" >> freddy.txt
            fi
    done < fred

Any better?

PS:  Note that those are back ticks (grave accent) surrounding the 'du' 
statement.
