Welcome to fdisk (util-linux 2.26.2).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.
Command (m for help): Created a new DOS disklabel with disk identifier 0xf60a308f.
Command (m for help): Partition type
p primary (0 primary, 0 extended, 4 free)
e extended (container for logical partitions)
Select (default p): Partition number (1-4, default 1): First sector (2048-351651887, default 2048): Last sector, +sectors or +size{K,M,G,T,P} (2048-351651887, default 351651887):
Created a new partition 1 of type 'Linux' and of size 167.7 GiB.
Command (m for help): The partition table has been altered.
Calling ioctl() to re-read partition table.
Syncing disks.
