How to split a hard drive (Make a partition) using Windows Disk management tool

Frequently Asked Questions

What is disk partitioning and why should I do it?

Disk partitioning is the process of dividing a physical hard drive into multiple logical sections, called partitions. This is useful for separating your operating system from your personal files, improving data backup efficiency, and enhancing overall system organization and performance.

Can I split a hard drive without third-party software?

Yes, Windows includes a free, built-in tool called Disk Management that allows you to create, delete, and format partitions on your hard drive without needing to purchase or install any third-party software.

What do I need before I start partitioning a hard drive?

You need administrator access on your Windows computer. Additionally, your hard drive must have unallocated or free disk space. If there isn’t enough free space, you can create some by deleting an existing partition, but ensure you back up any data on it first.

What is the difference between creating a partition and formatting it?

Creating a partition allocates a section of your hard drive for a new volume. Formatting prepares that partition to store data by creating a file system. You must format a partition before you can use it to store files.

Dividing disk space is known as disk partitioning. For partitioning purpose, we divide one physical hard drive into separate volumes.

Generally, hard disk drives come from factory with only one partition and shows one drive on your computer upon plugging in. Often, having a single drive limit the usefulness. For efficiency, you have to keep your windows file and other OS specific data separate in one single drive.

Separate partitions for Windows files and other data have a few advantages. If you create a separate partition on your hard drive, your computer will handle these partitions as individual entities. Keeping your data separate from the system drive (where windows is located), will provide an easier way to back up and lesser the chance of losing your valuable data.

You can create a separate partition by using third-party software, but that can be expensive in some cases. No need to worry, Microsoft already has included a Disk Management tool in Windows that will come to our help in this article.

You will need administrator access to create partitions or volume on hard disk. For creating a new partition, hard disk should have unallocated disk space or free disk space on the main disk drive. In case of not having any, you can create some by deleting a partition.
