 60GB HDD only recognised as 57GB?

I've just installed a new 60GB HDD. The BIOS sees it as 60GB, but in XP
Home's Manage function before ANY partitions have been allocated, the little
map is saying only 57GB is unallocated and available...

Do I need to RMA the drive to the supplier?

TIA

How can you see it if it has no partitions? Did you FDISK and Format?

It's all mathematics :-)
hard drive manufacturers say that 1Mb = 1000 Kb, everybody else says that it
is 1024.
Different software will give you different results depending on things like
rounding.

You are getting caught up in numbers, and in error.

Drive sizes are not exact.  For one thing, if you check the mfr's info,
you'll find that the drive size is specified as *unformatted*.  Once the
drive is formatted, space is allocated for various functions.

Second is a math issue, the issue of how 1024 does not equal 1000;  if you
check any folder size in DOS, in Windows Explorer, or by adding up the file
sizes, you will get completely different numbers.  For example, a standard
2HD floppy disk is spec'ed as 2MB, but by the time you use it (formatted) it
holds 1.44MB.

Just relax;  it's normal, there's nothing wrong, and you haven't been ripped
off.  And don't expect to use the full capacity of that drive for files,
either!  Some 10-30% of drives can be allocated just to directory
information (after all, those long filenames have to be stored *somewhere*.)

Harddrive manufacturers do not use actual MB and GB - if you look on the
box, they say 1gb = 1,000 mb and so forth.
Basically, they say that 60gb= 60000000000 bytes, Divide that by 1024 a few
times to get back down to gb, and you get 55.87GB. (57220MB)

It's all the same... a 120gb harddrive is actually slightly over 111gb.

        Believe it or not, this is just about right.

        See - most humans, and most marketdroids, compute numbers as powers
of ten.  So, a gigabyte is 1,000,000,000 bytes, or 10 to the ninth power.

        The COMPUTER, OTOH, computes in powers of TWO.  A gigabyte is two to
the thirtieth power.

        That number is 1,073,741,824 - a 7 percent variance.

        Add to THAT, the same drive can be measured in mixed units, such as
a gigabyte being 1,000 binary megabytes, or 1,048,576,000 bytes.

        I'd be willing to bet that the BIOS is actually showing 60,000 or so
MEGABYTES, and that Disk Administrator is showing the proper 57 GIGABYTES.

        Nope.

        Consider it the equivelent of "Batteries Not Included", "Your
Mileage May Vary", "Tax Title License additional", "Some Limitations Apply"
et cetera.

Thanks for your replies people.

Ok, here's some math for you:

The new 60GB drive shows 61496MB in the BIOS, which = 60.05GB if you divide
it by 1024.

The XP map only shows 57GB available.

I also have a pair of 20GB drives. They show 20497MB in the in the BIOS  =
20.01 GB if you divide it by 1024.

The XP map for these shows 19.07GB available, which I can live with and I
think is more reasonable.

I understand all about 1000 and 1024, but I feel like I've got ripped off
for 5% of my drive's alleged capacity.

Have I missed something...? Are my calculations incorrect?

TIA

Nope, you've installed a 57GB drive. See below.

allocated, the little

All hard drive manufacturers, in a deceptive attempt to make
their drives sound bigger than they are, define 1GB as
1,000,000,000 bytes. However the rest of the computer world,
including Windows, defines 1GB as 1024 x 1024 x 1024
(1,073,741,824) bytes. So your drive is 60 billion bytes, which
is the same as 57GB.

Now measure the size of your 17" monitor.

        Well, let's look at that.

        If the BIOS was using DECIMAL powers for the number, that would be
approximately 61,496,000,000 bytes, right?  Divided by the BINARY powers,
and that ends up 57.27 sump'n binary gigabytes.

        We're right on then - one's counting a gigabyte as 10^9, the other
as 2^30.

        Again, it's the same factor.

        Heh.  It's the SAME percentage, and that's the main point.

        Think of it this way.  You're an American, live in America, but you
cross the border to Canada to work.  You're told you're going to get paid
$610/week Canadian.  When you deposit the check, you get $572 American.

        You're not getting GYPED - those Canadian dollars aren't as big as
American dollars <grins!>

        (Note:  Yes, I am WELL aware that the current exchange rate isn't
even that favorable.  I'm just using it as an example.)

        Another one is - Quick!  What shoe size do you wear?

        If a Size 10, then my Size 10 shoes will be VERY loose on your
feet - since a woman's Size 10 is more like a man's Size 8 here in the USA.
Not to mention a woman's "Medium Width" would kill most men's feet - since a
woman's medium is usually an "A" width, and a man's medium is a "D" width
...

        You're not getting gyped - you're just mixing number bases.

This debate stems from a hardware vs. software schism IMHO. 'K' comes from
the resistor color coding scheme. When the third band denoted a value above
three zeroes the popular way to describe the resistor's value was in 'Ks'.
So when a resistor was so specified as 10,000 ohms we referred to it as 10K,
for instance. Or 124K or 1.2K. When it got above a one million mark we
referred to it as a 'Meg.' One million ohms became one megohm.

When us hardware guys at Intel referred to the RAM and ROM we were designing
we just naturally called a 4096 byte RAM 4K. Lazy shorthand.

Now, marketing being themselves will take the most inflated numbers and push
it out the door.

It *says* 61496MB, but they mean 61496 million bytes. Divide
61,496,000,000 by 1024 three times (once to get KB, the second
time to get MB, and the third time to get GB) and you get 57.27.
That's the number of GB you have.

Yes, as above.

Same arithmetic as above.

You've only been "ripped off" in the sense that we all get
"ripped off" whenever we buy a hard drive. It's certainly
misleading.

1.Upgrading HDD - 120Gb from 60Gb

I have a DELL 8200, that currently has a 60Gb HDD (56Gb), in 3 
partitions:
[C:\] = WinXP and Apps - 15Gb
[D:\] = My Documents - 10Gb
[E:\] = Backup Images (DriveImage 2002) - 31Gb

I'm purchasing a W.D. 120Gb and want to make it the *Master* and the
60Gb the *Slave*

My plan is to install the 120Gb as a *Slave* and using PM v7.01, copy
the existing partitions from the 60Gb to the 120Gb.

Then swap the drives around and sort out my usage.

Is there an *easier* way to achieve this?
What do I need to look out for?

TIA
