"Missing" 1.94 GB on hard drive

[Unknown]

Each spec notes 512 byte per sector. What format?

You appear to know something that no one else in the world knows, not even
the manufacturers of hard drives. Here are data sheets published by hard
drive manufacturers, all mentioning sectors:

Seagate:
http://www.seagate.com/docs/pdf/datasheet/disc/ds_barracuda_7200_11.pdf

Fujitsu:
http://www.fujitsu.com/downloads/COMP/fcpa/hdd/mhx2300bt_datasheet.pdf

Toshiba: http://sdd.toshiba.com/techdocs/MK2004GALUserGuide.pdf

HP: http://h18000.www1.hp.com/products/quickspecs/11531_na/11531_na.pdf

And the list goes on ...

Let me give you this test! Is there the same amount of sectors (your words)
on
the outer track as the inner most track of a HD?

How is this relevant to your preposterous claim?

In any case, the answer is: it depends. Historically the number has
been the same, but this is not true of drives that use ZBR (see
(http://www.webopedia.com/TERM/Z/zoned_bit_recording.html and
http://en.wikipedia.org/wiki/Zone_bit_recording). Such drives have a
variable number of SECTORS per track, depending on the track.

Who cares what format? If their hard drives have 512 bytes per sector,
then they have sectors, no matter the format.

What if it is NTFS???????? 512 bytes per sector? What sector?

You can tell me I am mistaken but it is my understanding that drives are
provided by hard disk manufacturers unformatted. The drive in question
was not formatted as NTFS but as HPFS.

Quote from link:
A more efficient use of disk space (files are not stored using
multiple-sector clusters but on a per-sector basis)

Hope this helps.

The file system is irrelevant. A hard drive has sectors, as listed on
numerous HD manufacturers specs. A file system imposes its own logical
structure on top of the physical structure of the HD, and the file
system may or may not have a logical unit corresponding to a physical
sector. I can imagine a file system, for example, whose smaller unit of
storage were 1K, and it could call that unit of storage a block, or a
cluster, or a page, or whatever it liked: but the underlying physical
sectors are still there.
