Furthermore, this guide will discuss how to create new partitions, and resize volumes.

Let’s begin. 

What is Disk Management?

Disk Management in Windows 10 is a built-in utility that lets you manage several storage activities, such as:

  • resizing volumes by extending or shrinking them and 
  • establishing or formatting hard drive partitions. 

Here’s another way to put it. When you connect an internal drive to your computer, it doesn’t display in File Explorer. Windows treats it as a blank slate with no allocated space. 

Disk Management lets you set up partitions, assign space, and make the drive usable in the operating system.

We’ll show you how to open Disk Management in Windows 10 and use it to partition your drives and more in the next sections.

How to Use Windows Disk Management?

You can use Disk Management to accomplish numerous tasks. However, before you make any changes, make sure to open D Management with administrative privileges. 

Proceed with caution when making any changes in the partition management, especially with existing data. If you plan to make changes, back up all necessary information before proceeding.

Initialize a Disk Before Using It

First, initialize a disk on your computer before you store any data. If you don’t initialize it, it’ll be unusable. 

Initializing a disk means getting a new or used hard drive ready for your computer to use. When you initialize a disk, you make a partition and format it using a file system that is readable and writable by your operating system

You must initialize your disk before you can store any data on it. Until you do this, it’ll be unusable. 

Also, even if you’ve used the disk before, it’s still crucial to initialize it again to fix any system errors. Ensure the disk is online by right-clicking and choosing ‘Online.’ 

Then, right-click on the newly created disk, select “Initialize new disk,” select MBR or GPT style in the window that appears, and press “Enter.” 

The Master Boot Record (MBR) and GUID Partition Table (GPT) are two different partitioning styles in Disk Management. MBR has a maximum of four primary partitions or three primary partitions and one extended partition. On the other hand, GPT supports a maximum of 128 partitions on a single disk. If you want to check whether you’re using MBR or GPT, right-click on the disk, select “Properties,” and click the “Volumes” tab

Allow the Disk Management to initialize the disk. 

Add or Change a Drive Letter

You can also use Disk management to add or change the drive letter. Every drive has a letter assigned; sometimes, you may want to change the drive’s letter for a specific drive. 

If you want to change a volume’s drive letter, follow the below steps: 

  • Open Disk Management. 
  • Select a volume or drive, right-click, and select “Change Drive Letter and Paths.” 
Change driver letter and paths
  • Click “Change” if you want to change the drive letter. However, if the volume doesn’t have a letter assigned, click “Add.” 
Change drive letter and paths for D
  • Choose your preferred letter from the drop-down menu and click “OK.”
Assign the following drive letter
When you click “OK,” you’ll receive a warning that some programs that rely on the drive letters might not function properly. So, we recommend not changing a drive letter where Windows and other programs are stored

Extend or Shrink a Volume

Partition resizing is usually done to use unallocated storage and reallocate space. 

For example, if you don’t have enough storage space on drive D but you have multiple partitions, you can shrink other partitions’ volumes to make space for drive D. 

Here’s how to shrink a volume: 

Right-click on the partition to shrink and select “Shrink Volume.”

Disk management shrink volume
  • Enter the amount of space you want to shrink. You can also select the available shrink space and click “Shrink.” 
Enter the amount of space to shrink

Here’s how to extend a volume:

  • Right-click on the volume to extend and select “Extend Volume.”
Extend volume
  • Click “Next” when a window pops up. 
  • Enter the amount of space you want to extend or use the default available space and click “Next.” 
  • Click “Finish” to complete the process. 

Create a New Partition or Volume

You can create a new partition on your drive if free space is available or shrink a volume to make new space. However, before you create a partition, check to see if you have unallocated space. 

Here’s how to create a partition: 

  • Select the unallocated space, right-click, select “New Simple Volume,” and click “Next.” Usually, unallocated spaces come with a black bar. However, you can customize it in settings. 
Specify volume size
  • Enter your desired volume or use the default maximum volume size. 
  • Next, assign a drive letter to the volume. 
  • Choose to either format the partition or ignore it. However, it’s always advisable to format when creating a partition.
Format partition
  • Click “Finish” if everything is okay for you. If not, click “Back” to make the necessary changes. 


Disk management in Windows 10 helps you maximize the space on your PC.

This guide gives you the know-how to improve your storage skills, from launching a disk, changing drive names, and adjusting partitions to accessing the utility using various methods.

However, proceed with caution when making changes in Partition Management. It’s always best to back up your data before proceeding. 


Yes. You can use Windows Disk Management to resize your system partition. You can do that by right-clicking on the Start menu and selecting “Disk Management.” Search for the system partition, right-click, and select “Shrink Volume” or “Extend Volume” depending on your preference. Follow the on-screen prompts to adjust the partition size. 

If your solid state drive doesn’t display in Windows 10 Disk Management, there could be a lot of reasons. First, it’s possible that the SSD is incorrectly or physically disconnected from the computer. Also, if it’s an external SSD, there might be a problem with the USB port or cord. The SSD may not display if it has a faulty partition table or is not initialized. Also, if there are driver problems or the SSD is incompatible with the operating system, it may not be detected. 
Yes. You can merge two partitions using Disk Management. The first step is to open Disk Management, search for the partitions you want to merge, and make sure there’s an unallocated space next to one of them. Move your cursor over the first partition and select “Delete Volume.” Then, move your cursor over the second partition and select  “Extend Volume.” Follow the on-screen prompts to combine the divisions. Remember that you can lose data on the second partition. So, make sure you back up your data before proceeding.
