Overview: What Disk Partition Meant for You?
Some disks are equipped with a single partition in default, but most come with an unallocated space without a partition. Unpartitioned drive can't work - Internal hard drive, external hard drive, and removable devices (USB drive, flash drive, memory card, memory stick, etc.) which contain storage space must be partitioned. So this article is written for those who want to partition but lack basic info. Read on to see what is disk partitioning, how to partition a hard drive, etc.
A hard disk partition is a division of a hard drive or other storage devices into multiple, independent compartments. Partitions are typically created to help keep programs and data organized, allowing different kinds of information or operating system to be stored in separate places.
You can see what a partition looks like on Disk Management. Those tiny boxes behind the disk 0 or 1 are the ones.
Disk Partition Types - Primary Partition, Logical Partition and Extended Partition
Disk partition types can be generally classified into three types: primary partition, extended partition, and logical partition. A hard disk can have one to three primary and one extended partition, or it can have only primary but no extended partitions. However, you must create at least one primary partition and a maximum of one extended partition, and the total number of primary and extended partitions cannot exceed four. There can be several logical partitions.
Hard Disk Partitions and File System
After partitioning a hard drive, you need to format the partition with a file system and store data.
- Windows drives - NTFS file system.
- Removable devices - exFAT, FAT32 file system.
- Linux Partition - ext2/3/4 file system.
- Mac drives - APFS, HFS, HFS+ file system
Is Disk Partition Needed?
At least one partition is needed! You cannot store files or programs on a blank, unpartitioned drive.
