Partition using parted

parted is a more advanced tool than fdisk, suitable for both MBR and GPT partitioning.

Steps:

• Open parted with the target disk:

sudo parted /dev/sdX

Sample Output:

GNU Parted 3.2
Using /dev/sdb
Welcome to GNU Parted! Type 'help' to view a list of commands.
(parted)

• Set the Disk Label (only if you want to create a new label like GPT or MBR):

(parted) mklabel gpt

Sample Output:

Warning: The existing disk label on /dev/sdb will be destroyed and all data on this disk will be lost. Do you want to continue?
Yes/No? yes

• Create a New Partition:

(parted) mkpart primary ext4 1MiB 5GiB

• primary is the partition type.
• ext4 is the file system type (optional).
• 1MiB is the start point, and 5GiB is the end point of the partition.

Sample Output:

(parted) mkpart primary ext4 1MiB 5GiB

• Quit Parted:

(parted) quit

Sample Output:

Information: You may need to update /etc/fstab.

• Format the New Partition:

sudo mkfs.ext4 /dev/sdX1

Sample Output:

mke2fs 1.45.5 (07-Jan-2020)
Creating filesystem with 1310720 4k blocks and 327680 inodes
Filesystem UUID: a8c9c2d4-8e9c-432b-8ae4-d6e94cbd1e59
Superblock backups stored on blocks: 
    32768, 98304, 163840, 229376, 294912, 819200, 884736

• Mount the Partition:

sudo mkdir /mnt/new_partition
sudo mount /dev/sdX1 /mnt/new_partition

Sample Output:
