1. List the disks
lsblk
2. Find the disk and grep for SCSI
dmesg | grep SCSI
siftuser@docker-registry:~$ dmesg | grep SCSI
[ 0.784137] SCSI subsystem initialized
[ 2.239054] Block layer SCSI generic (bsg) driver version 0.4 loaded (major 244)
[ 3.236693] sd 0:0:0:0: [sda] Attached SCSI disk
[ 3.598509] sd 1:0:1:0: [sdb] Attached SCSI disk
[ 5.124510] sd 3:0:0:0: [sdc] Attached SCSI disk

Here sdc is the disk that we want to Partition
3. PARTITION DISK - Start the FDISK PROCESS
sudo fdisk /dev/sdc
siftuser@docker-registry:~$ sudo fdisk /dev/sdc
Welcome to fdisk (util-linux 2.31.1).
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 0x5ad69206.
Command (m for help): n
Partition type
p primary (0 primary, 0 extended, 4 free)
e extended (container for logical partitions)
Select (default p):
Using default response p.
Partition number (1-4, default 1):
First sector (2048-104857599, default 2048):
Last sector, +sectors or +size{K,M,G,T,P} (2048-104857599, default 104857599):
Created a new partition 1 of type 'Linux' and of size 50 GiB.
Command (m for help): w
The partition table has been altered.
Calling ioctl() to re-read partition table.
Syncing disks.
4. Write a file system to the partition using mkfs
siftuser@docker-registry:~$ sudo mkfs -t ext4 /dev/sdc1
mke2fs 1.44.1 (24-Mar-2018)

5. Make a DataDirectory
siftuser@docker-registry:~$ sudo mkdir /datadrive
6. Mount the data directory
sudo mount /dev/sdc1 /datadrive
