linux_mounting_device.sh

fdisk -l

# we assume our new device/drive is named '/dev/sdb'.

fdisk /dev/sdb

	################################################
	
	[/sociallocker] Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
	Building a new DOS disklabel with disk identifier 0x2e3c77cd.
	Changes will remain in memory only, until you decide to write them.
	After that, of course, the previous content won't be recoverable.
	Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)
	WARNING: DOS-compatible mode is deprecated. It's strongly recommended to
	switch off the mode (command 'c') and change display units to
	sectors (command 'u').

	Command (m for help): 

		=> n

	Command action
	e   extended
	p   primary partition (1-4)

		=> p

	Partition number (1-4): 1
	First cylinder (1-1566, default 1):
	Using default value 1
	Last cylinder, +cylinders or +size{K,M,G} (1-1566, default 1566):
	Using default value 1566

	Command (m for help):

		=> w

	The partition table has been altered!
	Calling ioctl() to re-read partition table.
	Syncing disks.

	We have used ‘n’ to create a new partition, p to create the partition as primary, 
	1 to specify the partition number and used defaults for begin and end range for partition size.

	Finally ‘w’ to make changes permanent.
