the first 4 bytes of your class. mtt.sizeof is the size of the reference
not the size of the object itself.

s.ptr is the pointer to the array data.
&s is the address of the struct, that holds the array length and the
pointer to the data.
To write the string, you might want to try this:
	myFile.writeExact( s.ptr, s.length );
