Formatting A Large HDD Linux In The Command Line
The following process below can be used to format a large HDD via the CLI, and also includes a portion to change the reserved blocks which I'd only suggest using on an HDD that isn't part of a critical workflow/workload. I pulled most of this information from one of my favorite youtuber's, Jeff Geerling, blog article found here. I would also highly, highly recommend Mr. Geerling's Youtube Channel.
How to format a large disk:
$ sudo parted /dev/sda
(parted) mklabel gpt # to create a partition table
(parted) print # to verify parition info
(parted) mkpart primary 0% 100% # create primary partition filling entire disk
(parted) quit
$ sudo fdisk -l /dev/sda
Disk /dev/sda: 7.3 TiB, 8001563222016 bytes, 15628053168 sectors
Disk model: Samsung SSD 870
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: gpt
