Hard Drive Partitioning

KB ID 0000078 Dtd 09/11/09

Problem

This
page deals with "Simple Partitioning" though reference
will be made to how newer operating systems use partions.

Common
Misconceptions

"All
Partiions have a drive letter" NO

"All
drive letters are a separate partition" NO

Solution

OK
then! Take a hard drive, I will show it below as a "large
block of space"

If
you are only going to have one partition and its going to
be your only drive letter then you would simply put in a PRIMARY
PARTITION and set it to ACTIVE (So it can be booted from)
once it has been formatted it will be the only drive (Usually
C:)

However
if you want the hard drive to appear as multiple drive letters
c: d: etc then you need to partition it differently, you will
still need your primary partition but it WONT fill up the
entire drive space.

Now
comes the confusing bit, if you want any more drives you need
to create an EXTENDED partition. An extended partition will
have NO drive letter assigned to it and cannot be formatted
(Bear with me :0)

extended partition

It
is in the EXTENDED partition you can create further drives,
create them one by one to fill up the extended partition –
unless you want to leave some space for the future. Each of
these drives are called LOGICAL DRIVES, and when formatted
each will have its own drive letter.

This
system is used by Operating systems like Windows 95/98/ME
modern Operating systems like Windows 2000 and XP can utilise
up to 4 Primary partitions, but lets keep things simple.

To
set this up you would normally use the command line utility
FDISK, Remember partitions MUST be created in this order Primary,
Extended then Logical. And if your deleting partitions you
MUST delete them in reverse order, Logical, Extended then
Primary.
