[edit] สร้างพาทิชั่นใหม่

#fdisk  /dev/sdb1
# n
# p
# 1
# enter
# enter
# w

=>Fdisk will display the following menu
Command (m for help): m
Command action
a toggle a bootable flag
b edit bsd disklabel
c toggle the dos compatibility flag
d delete a partition
l list known partition types
m print this menu
n add a new partition
o create a new empty DOS partition table
p print the partition table
q quit without saving changes
s create a new empty Sun disklabel
t change a partition's system id
u change display/entry units
v verify the partition table
w write table to disk and exit
x extra functionality (experts only)

Command (m for help):

=> We want to add a new partition. Type "n" and press enter.
Command action
e extended
p primary partition (1-4)

=>We want a primary partition. Enter "p" and enter.
Partition number (1-4):
=>Since this will be the only partition on the drive, number 1. Enter "1" and enter.
Command (m for help):
=> Now that the partition is entered, choose option "w" to write the partition table to the disk. Type "w" and enter.
The partition table has been altered!
=>If all went well, you now have a properly partitioned hard drive that's ready to be formatted.
