NTFS was an outgrowth of HPFS.  In contrast to HPFS, it's supposed
to be a "journaling" file system whatever that means.  Also
for HPFS the cluster size is fixed (512 K if I recall). I have noticed
that NTFS seems to set aside a fairly large Master File Table (if
I've got the term right) as a contiguous block.  There's no such beast
in HPFS which has a lot "nodes", "extended attributes" & other small
reserved clusters/blocks scattered across a drive. Clearly there's 
been much evolution between HPFS and NTFS as it exists in NT4.

The basics of HPFS and NTFS should be covered in articles in the
MS Journal if that still exists.  Remember reading an article 
about hpfs some years back.
