The fixed width numbers are easy with something like: (3 digits)
case $i in
 ?)
  i=00$i
 ;;
 ??)
  i=0$i
 ;;
esac

The real problem, though is that you can't feed the script from a
pipe.  dd is almost unique among the unix tools in that it
uses read() rather than fread() and will fail to read the
requested amount if the input pipeline cannot stay ahead.
