Welcome to fdisk (util-linux 2.23.2).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.
Device does not contain a recognized partition table
Building a new DOS disklabel with disk identifier 0xe0dc5856.
Command (m for help): n
Partition type:
p primary (0 primary, 0 extended, 4 free)
e extended
Select (default p): p
Partition number (1-4, default 1): 1
First sector (2048-37748735, default 2048):
Using default value 2048
Last sector, +sectors or +size{K,M,G} (2048-37748735, default 37748735):
Using default value 37748735
Partition 1 of type Linux and of size 18 GiB is set
Command (m for help): w
The partition table has been altered!
