Hi,

If a new hard disk is 80GB, what is the space taken by the system to
format it in NTFS.
Because when i check the properties of the Hard Disk and without saving
anything into it, it doesn't show 80GB available...

An 80 Gig hard drive has actually only about 73 gigs of space, the mfgs. use
a little creative calculating on the size of hard drives. Figures don't
lie....but liers do the figuring!

WinXP, like other operating systems, measures kilobytes, megabytes,
and gigabytes as:

1 Kb = 1024 bytes
1 Mb = 1024 Kb = 1,048,576 bytes
1 Gb = 1024 Mb = 1,073,741,824 bytes

However, a common marketing ploy used by hard drive manufacturers
to make their products seem a bit larger than they really are is to
assign the value of an even 1,000,000,000 bytes to the gigabyte.

If you were to divide your hard drive's advertised size of
80,000,000,000 bytes by 1024, you'd get a result of 78,250,000 Mb, which
is probably closer to what WinXP is reporting. The difference is a
result of the manufacturer rounding off the true size of the drive to
"80 Gb."

It has nothing to do with space taken by the operating system.

You don't have an 80GB drive, you have a 74.5GB drive. All hard drive
manufacturers define 1GB as 1,000,000,000 bytes, while the rest of the
computer world, including Windows, defines it as 2 to the 30th power
(1,073,741,824) bytes. So a 80 billion byte drive is actually a little under
75GB. Some people point out that the official international standard defines
the "G" of GB as one billion, not 1,073,741,824. Correct though they are,
using the binary value of GB is so well established in the computer world
that I consider using the decimal value of a billion to be deceptive
marketing.
