can

result

 

in

slower

performance.

Therefore,

 

small

partitions

are

well

 

suited

for

 

small

 

files

 

while

large

 

clusters

 

are

well

 

suited

to

large

files

for

optimal

 

capacity

and

 

performance.

 

 

 

 

 

 

 

 

 

 

 

 

If

you

replace

a

hard

disk

drive

with

a

 

much

larger

 

capacity

drive,

 

normally

you

will

create

 

a

larger

 

partition

 

size

on

the

new

drive.

 

When

you

 

copy

files

from

a

smaller

partition

to

a

 

larger

partition,

the

same

files

 

require

surprisingly

more

 

space

on

 

the

disk

 

because

of

the

 

increased

cluster

 

size.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The

latest

releases

of

 

Microsoft

 

operating

 

systems,

 

originally

available

 

only

to

systems

manufacturers,

have

an

option

for

a

32-bit

file

 

 

allocation

 

table

called

FAT32.

FAT32

 

supports

 

partitions

 

as

large

as

2

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

terrabytes

(2,048

and

cluster

sizes

of

4

KB

 

for

partitions

up

to 8

These

examples

illustrate

 

the

 

effect

of

 

cluster

size

on

hard

disk

space

 

GB.

If

 

you

have

FAT32,

you

will

be

able

to

set

without
