I don't exactly follow what you are saying here. An NTFS partition can be
any size (max = 2^64 = about 18.5 Million TeraBytes). Perhaps the maxtor
utility has a false minimum limit. What does it suggest to use for 33GB as
Fat32 is (falsly by windows) limited to 32GB, so if NTFS isn't allowed until
you reach 34GB, then 33GB is in "no man's land"!
The reason you are 'losing' over 10GB is this:
There is a problem with the term GB - it can be interpreted in 2 ways by
people with different backgrounds/outlooks. Some follow the mathematical
definition that Giga means 10^9 (1,000,000,000) and others follow the other
meaning (not sure what the dicipline is called) of Giga which is 2^30
(1073741824). This second term is sometimes refered to as Gibi (GIga in
BInary).
The marketing people at maxtor (and other drives), use the mathematical
definition to describe their drive capacities. So your 160GB drive holds
160,000,000,000 Bytes (mathematically accurate). Windows reports drive sizes
using the other definition, so to windows your drive holds 160 / 2^30 =
149GB.
Strange but true - the only industry or dicipline in the world where 160GB =
149GB! But this is probably where you are 'losing' over 10GB of space. The
answer is that you aren't losing the space, its just windows reporting the
size wrongly.

I would say Windows is reporting it correctly, the Manufacturers have
changed the way of SELLING hard drive space.

And you are not alone in being brainwashed by microsoft! This is the big
debate - one that tends to end it threads going 30+ replies deep and never
actually getting anywhere!
Nobody can argue with this mathematically accurate statement:
160,000,000,000 => 160 x 10^9
The problem for some people (microsoft) is when we introduce the recognised
scientific exponential abbreviation for 10^9, Giga:
160,000,000,000 => 160 x 10^9 => 160GB
As you can see, I side with the mathematicians and agree that windows has
got it wrong because Giga means 10^9 for any numerical expression of
quantity. Similarly, Mega means 10^6 and Kilo means 10^3.

Because that's not how words are defined. Words are defined by usage.

There are other arguments, besides, definitions don't necessarily
follow what you consider to be the best logic. Definitions are what
human beings want them to be, whether a particular individual or group
of individuals like it or not. Mathematicians might want it one way,
engineers who design integrated circuits that move data to and from a
hard drive platter might want it another way. If you see it in the
dictionary, that's probably because educated speakers use that
definition, since that's where definitions come from.

A fair point - Giga has been used to mean 10^9 for decades, if not
centuries!

Both are inaccurate.
The drive-makers tend to over-list a drive ... but not nearly as badly
as they used-to. "Back when", companies would list a drive's RAW
byte-count, before formatting. IOW, the number of bits the controller
could write from index-to-index divided by eight.
This practice stopped (and was already dying) when they went to SCSI and
ATA drives with internal formatting, where the user *couldn't* write a
whole track as a single block.
However drive-makers even then tended to call all of the extra (but
hidden) sectors on a drive that are used to reallocate defects as part
of their advertised "size".
They *still*, even now, tend to use decimal byte-counts (which look
bigger) than megabyte-counts (1024 bytes = 1Kb, 1,048,576 bytes = 1Mb,
1,073,741,824 bytes = 1Gb) to count how big a drive they're selling.
Those (of course) are RAW bytes available to the OS to use (supposedly).
To actually *use* a drive however, doesn't leave *nearly* that many for
the user.
1. Every drive has to have a "boot sector" set aside and written
(actually, far more than just a single sector, these days) it must also
be "partitioned" a "formatted.
2. When partitioned, some of the space is lost defining the partition.
Also, far more space is lost in various formats that don't allow
partitioning the full space available; so there's some unpartitioned
space left over in almost every drive these days. The bigger the drive,
the more likely. In my 160-gig drive (for example), even when I tell
Windows to partition the entire drive as one huge volume, 8 gig is left
over. ;-{
It seems a bit of a waste to not use 8 gigabytes; but far more to waste
a drive-letter for something that small these days. (Eight *gigs* is
small?)
3. Finally, in "formatting" a drive, space is needed on the drive for
the operating system to tell where things are stored. Spaces for
directories, "FAT tables" or the equivalent, and other information.
Even if (like in some OS schemes) they just start with a basic simple
directory-structure that can be expanded; with directories just being
another type of file, and locations stored similarly, when you end up
with much of the disk space used, the directory structure still takes up
considerable space that cannot be used by other files.
Windows doesn't count all those as space on the disk when it reports a
drive's "size".
So: Who is wrong?
Neither, both.
Depends on your viewpoint.
You just have to keep it in mind when buying a drive that a certain
percentage of the drive's "sale size" won't be left as "user size".

Not really, we are talking about a 160GB drive here, which has 160 Giga
Bytes (160,000,000,000) of space. Pretty simple!

Only if it is a system drive. A second hard drive in a system doesn't need a
boot partition.

Why did you leave 8GB behind? Following installation of my new system drive,
I partitioned my Samsung Spinpoint 160GB 2 days ago, using windows and I am
using the full 160GB, there's is no 8GB space left! That's 160 Giga Bytes as
in 10^9. No approximations, no rounding, a pure 160GB. If you want me to
approximate it using some bizarre inaccurate power of 2, then its 149.05GB,
but we are still talking about 160,000,000,000 in 1 partition.

That is like saying part of an encyclopedia is lost space because there are
50 pages of index!

Yes it does. Program Files, Administrative tools, Computer management, Disk
Management, overhead column.

Everybody thinks they are right (including me!)

Well actually, as mentioned, I have my Samsung Spinpoint 160GB drive as a
'files' disk. It has a raw capacity of 160,000,000,000 Bytes. There is no
boot partition. There is some space *used* as the index (FAT), but this is
space on the drive that exists and is being used, so is not 'lost'. The size
of the parition is reported using a binary approximation as 149.05 gB, where
g = 1073741824 (Gibi (g), not Giga (G)). So as a mathematical quantity, or
actual number, there are 160,041,218,867 Bytes in the partition, marginally
more that the actual capacity due to rounding errors in the calculation! So
wasted/lost space = 0.0000000%.
Sorry folks (and nothing personal Frank), but this subject really gets me
going - its such basic mathematics, it really annoys me when people choose
to use very new, alternative and wrong definitions for clearly defined terms
that have been around for a very long time.

I've noticed that when partitioning a drive using the Windows XP/2000
installer, a small portion is always left unallocated. It's 8 megabytes
though, not 8 gigabytes.
