I tested by wc(1) instead of cat, and succeeded.
Here is my test script. What is the difference?
sudo mount -o remount,udba=none .
mkdir ubifs
stat -f . $rw
for i in 511 512 513
do
yes | /tmp/mydd bs=$i count=1 of=$rw/ubifs/b$i
sleep 1
stat $rw/ubifs/b$i > $tmp
stat ubifs/b$i | diff -u $tmp - && false
wc -l ubifs/b$i
done
