Partitioning and formatting of disks

What is a disk partition

Disk partitioning refers to the logical partitioning of physical media on a hard disk. Partitioning a hard disk into multiple partitions is not only beneficial for managing files, but different partitions can create different file systems.

There are three primary partitions, extended partitions, and logical drives in a disk partition.

What is formatting

After the disk is partitioned, the next step is to format the disk partition (that is, the work of creating the file system)

using fdisk disk partitioning

You can use the Fdisk command to divide a disk into partitions, and you can specify the type of partition for each partition.

Fdisk/dev/sdb
