NTFS was added in NT 3.1 (which predates Win2K by 7-8 years).
However, I don't remember anybody using it much until a year or
two later around NT 3.5
Which makes one wonder if perhaps the change in behavior under
NT/2K/XP wasn't the security system zeroing out intervening
sectors but rather the filesystem not allocating them at all
and returning 0's when one read a "hole" in the resulting
sparse file.

Not to worry, the thought hadn't occurred to me.
