Welcome to fdisk (util-linux 2.25.2).
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.
Created a new DOS disklabel with disk identifier 0x374a220b.
Command (m for help): n
Partition type
p primary (0 primary, 0 extended, 4 free)
e extended (container for logical partitions)
Select (default p): p
Partition number (1-4, default 1):
First sector (2048-2005431, default 2048):
Last sector, +sectors or +size{K,M,G,T,P} (2048-2005431, default 2005431):
Created a new partition 1 of type 'Linux' and of size 978.2 MiB.
Command (m for help): a
Selected partition 1
