Yes, that was my initial conclusion when I looked at the code trying to
redo that loop.

Ah right, that would work as well. Another possibility would be
to change NTFS_BLOCK_SIZE to 4096, at least in the affected configurations.

According to the documentation I linked to in my commit, file system images
with smaller block sizes should be extremely rare, but I have no idea if the
code would work correctly for normal images after that change.
