Yes. In your case [and quite probably in many others]. But the partition
can be much bigger than the NTFS volume size and chkdsk always creates the
backup boot sector in the last 512 bytes of the partition. Believe me, it
has nothing to do with cluster bitmap. Your case is pure accident.

So probably you will also need a mechanism to put data relative from the
volume end or handling this case as an exception (but in that case what
will be the next exception? ;)
