A disk partitioner can make life easy for PC & Mac users. But how do you choose the right one?

A disk partitioner is a remarkable tool to help you partition your disks. Considering the hassle it takes to clean up, format, or change the storage sizes, these programs can make a tedious task a lot easier. However, the problem is not finding the tool; it's finding a good one.

Then how do you pick a good disk partitioning tool? Is there science behind it, or do all the tools do the same thing? There are dependable tools. Then there are tools you can't strictly rely on because you need to ensure the safety of your data and the physical health of your disk.

So, let's dive right into it and find out.

What Is Disk Partitioner

Disk partitioning or disk slicing is the creation of one or more regions on secondary storage, so that each region can be managed separately (by Wikipedia). A disk partitioner is a tool that helps you break your hard disk into various partitions. So, let's say you have 1000GB of storage, and you wish to turn them into four partitions of around 250GB each; you can use a tool such as a disk partitioner.

There are various types of disk partitioners, and perhaps the most common one is built into our computers and Macs. Then, there are third-party tools. However, using a dependable tool has many benefits, such as:

  • Saving you from the hassle of doing it manually
  • Ensuring the security of your data
  • Breaking and creating partitions without formatting or losing data
  • Extending or increasing the size of specific partitions
  • Saving you a lot of trouble and time

These are some of the most common benefits of using a disk partitioner. If you use the common tool built into the Windows or Mac operating systems, you can do it. However, using a third-party tool is a little more viable, as they tend to cover various ends of creating or breaking partitions.

How to Get a Disk Partitioner? Top 5 Best Disk Partitioners for Windows and Mac

The easiest way to get a disk partitioner is by finding the one you have on your computer. However, to find a dependable third-party tool, you might have to do some research. But worry not, as we've already done the research for you.

Let's break down our tools into two categories; here are the ones you can find in your operating systems:

  1. #1. Disk Management (Windows)
  2. #2. CMD/Command Prompt (Windows)
  3. #3. Disk Utility (Mac)

Then, you can download two of the most dependable third-party tools, which are:

  1. #4. EaseUS Partition Master
  2. #5. GParted

Each of these tools can help you with partitioning your hard drive. But which one stands out as the best? First, let's talk about the in-built tools that we can use.

#1. Disk Management (Windows)

Disk Management is an in-built tool can be accessed by any Windows users:

  • Press Windows & type "Disk Management," then enter
  • Or, right-click This PC on your desktop and click Manage
  • Navigate the sidebar until you find Disk Management & click it

This in-built tool is excellent, but it does have a few restrictions. For example:

  • You can only increase a partition's size if you delete and remove another partition
  • You'll need unallocated space to Extend the volume

Therefore, it's a good tool only until you run into a few of the aforementioned problems.



  • Easy to use
  • In-built
  • Free


  • Restricted in some aspects

#2. CMD (Windows)

CMD, or command prompt, is perhaps the first thing we all learned about computers in school. However, this console is perhaps the most effective tool present within our operating systems. Here's how to access it:

  • Press Windows+R & type CMD
  • Type Diskpart and press enter
  • Type List Disk in the Diskpart console

As you can see, there are three disks here. You need to pick the one where you need to make your partition. So, for instance:

  • Type select disk 0
  • Then type create partition primary size=200,000 (200,000 being 200GB or the size you wish to partition)

You can simply type "create partition extended" if you want to extend a specific partition.



  • Easily available
  • Perhaps the safest & quickest


  • Too much hassle
  • You might mistype partition and lose data

#3. Disk Utility (Mac)

Disk Utility is perhaps the easiest way for mac users to create a partition. This tool is easily available on any Mac device.

Once you open it, you can follow a few steps to create a partition:

  • Select the physical drive from the sidebar
  • Click on the Partition button, which will look like a pie chart
  • Click on Add button, which looks like +, and then click Add Partition
  • Type a name (optional), then pick the volume type, i.e., MS-DOS or ExFAT
  • Choose the file system
  • Enter a size or drag the pie chart until you're at a number you like, i.e., 200GB
  • Click Apply, then click Partition (If prompted further, click on Continue)
  • Click Done once partitioning is finished


  • An easy-to-use tool
  • Easily available on all Mac devices


  • Won't be able to use some file systems created by Disk Utility on other operating systems, i.e., Windows

What Happens If I Interrupt Disk Partitioner

Formatting, partitioning, extending, or shrinking a hard disk drive is a risky business. You must always be 100% sure before you get started, regardless of which tool you choose to employ. If you interrupt a disk partitioner, then you can expect a cascade of failures.

This includes:

  • Data loss beyond recovery
  • Unresponding applications
  • Unresponsive computer
  • State of device reverse (Very rarely, unless you're using a third-party tool)
  • Inability to stop the format/extension/shrinking

You must always be sure before running a disk partitioner, as most operations cannot be halted once they start, such as partitioning a disk. In worst cases, you might also risk physical damage to the magnetic disk inside your hard drive. 

So, how can you be 100% and avoid this trouble? By using dependable third-party software like EaseUS Partition Master. It has an execute operation button, which double-checks on you before you format or partition a drive with it.
