The Disk Management tool in Windows gives you an easy-to-use graphical interface to dealing with partitions and drive letters , but what if you want to just quickly change a drive letter on the command prompt? The diskpart utility makes it easy.

You’ll need to start by opening an administrator mode command prompt — type cmd into the search box, and then right-click and choose Run as administrator, or use the CTRL + SHIFT + ENTER keyboard shortcut.

Once there, run the diskpart command, and then type in the following to list out the volumes on your system.

list volume

You’ll want to note the volume number next to the drive that you want to change the letter of. In our case, that number is 3.

Now we’ll use the select volume command to tell diskpart to make changes to that volume. If your drive number is different, you’ll want to replace the 3 with the number in your configuration.

select volume 3

You should see a message that the volume is now selected.

At this point you can easily assign a new drive letter. Just type in this command, substituting R for the drive letter you’d like to use:

assign letter=R

Make sure to hit enter once you’re done, of course.

Once you’ve made that change, your drive should show up again as a new device, and be available for browsing immediately.

If you want to unassign a drive letter in order to hide the drive, you can also use the remove letter command in the same way. We wouldn’t necessarily advise doing this, of course.

Don’t bother trying to change your C: drive, because that’s not going to work.

Everything About DiskPart Commands in Windows 10

DiskPart is a command-line utility in Windows 10/11, enabling you to perform disk partition operations with commands. Learn how to use DiskPart commands with typical examples here.

What is DiskPart?

DiskPart, replacing its predecessor - fdisk, is a command-line utility that provides the ability to manage disks, partitions or volumes in your computer running all versions of the operating system since Windows 2000, also including the latest Windows 10. Users can input DiskPart commands directly to organize hard disk partitions or create a text file script to perform multiple commands. Most disk partition operations that you can perform in Disk Management tool are integrated into DiskPart.

How to open DiskPart in Windows 10/11?

You will need to launch Windows 10/11 DiskPart with Administrator permission. One way is to type "diskpart" in the Search box, and then when diskpart appears in the search results, right-click it and select "Run as administrator". The other way is to press "Windows logo + R" keys and type "diskpart" in the box, and then click "OK".

Common DiskPart Windows 10/11 commands (examples study)

Before you can use DiskPart commands in Windows 10, you must first list, and then select an object to give it focus. When an object has been focused, any DiskPart commands that you type will act on that object.

At the DISKPART> prompt, type "list disk" to display all the disks in your computer. Each one will have a specific disk number, starting with 0. An asterisk (*) under GPT row means the disk is of GPT partition style. Unless there is only one disk, you will have to tell DiskPart which disk to manage by using "select disk n" command to give it focus. n represents the number of the disk.

At the DISKPART> prompt, type "list volume" to display all the volumes on all disks. Each one will have a specific volume number, starting with 0. To tell DiskPart which volume to manage, you need to type "select volume n" to give it focus. n can be the number of the volume or the drive letter of the volume if has.

To view what DiskPart can for you, just type help to see a list of commands.

Next, we will take some of the most common commands that Diskpart uses as examples for you to get a further understanding.

Section 1. Most common Diskpart commands on volume in Windows 10/11

Because when selecting a volume, the focus remains on it until you select a different volume, “select volume” command may not be used in each operation. Besides, the examples are performed one after one and the effect of the previous operation will be viewed in the next operation. If you only need to perform one of the operations, you need to select the volume before using the corresponding command.

➤ Note: Each time you type a command, you need to press "Enter" key to apply it.

1. Delete Volume

2. Create Partition

3. Format Partition

4. Assign Drive Letter

5. Extend Partition

6. Shrink Partition

7. Mark Partition as Active

To delete a volume, please refer to the following command:

▪ list volume

▪ select volume 6 (here take F: drive for example).

▪ delete volume

And then, you will receive a message says: DiskPart successfully deleted the volume.

Note: You cannot delete the system volume, boot volume, or any volume that contains the active paging file or crash dump.

To create a partition, please refer to the following command:

▪ create partition primary size=102400

And then, you will receive a message says: DiskPart succeeded in creating the specified partition.

The above command means to create a 102400MB (100GB) primary partition. To create other types of partition, you just need to replace primary with one of the followings:

➧Note: To create a partition, there must be unallocated space on the disk.

Type list volume command, you will find the new created partition is RAW, which means you must format partition before you can use it. To format a partition, please refer to the following command:

▪ format fs=ntfs label="Windows 7" quick

And then, you will receive a message says: DiskPart successfully formatted the volume.

The above command means to perform a quick format on the partition. It will be formatted with NTFS file system and labeled as Windows 7. To create other file system partition like FAT, FAT32, you just need to replace ntfs with fat or fat32. The label can be any name as you like.

➧Note: DiskPart cannot format 32GB+ partition to FAT32. To format a large hard drive to FAT32 , you have to turn to a third-party partition manager.

A partition without a drive letter will be hidden under "File Explorer". To assign a drive letter to an existing partition, please refer to the following command:

▪ assign letter=F (F can be replaced with another letter that has not been used yet).

And then, you will receive a message says: DiskPart successfully assigned the drive letter or mount point.

To extend a partition, please refer to the following command:

▪ extend size=20480

And then, you will receive a message says: DiskPart successfully extended the volume.

The above command means to add 20480MB (20GB) to the volume 6. If no size is given, all of the contiguous unallocated space on its right side will be added.

➧Note: To extend a partition, there must be contiguous unallocated space on its right side.

To shrink a partition, please refer to the following command:

▪ shrink desired=10240

And then, you will receive a message says: DiskPart successfully shrunk the volume by 10GB.

➧Note: You can reduce the size of a volume only if it is formatted using the NTFS file system.

To mark a partition as active, please refer to the following command:

And then, you will receive a message says: DiskPart marked the current partition as active.

Section 2. Most Common Commands on Disk in Windows 10/11

The most common diskpart commands used on the disk should be the MBR and GPT conversion. To delete all partitions or volumes on a disk and convert the disk between MBR and GPT, please refer to the following command:

▪ list disk

▪ select disk 1

▪ "convert gpt" or "convert mbr".

How to Use DiskPart Utility in Windows

Format, resize, extend and manage your drives

The Disk Management Tool is a useful, effective tool for managing your Windows disks and partitions, but it isn’t as powerful to use as Diskpart. This command-line tool lets you delete, create and modify partitions on any hard drives or USB storage your PC can detect.

We’d recommend using the Disk Management Tool for most situations, but if Windows isn’t starting up properly, or if you prefer to use the PowerShell terminal , Diskpart is the perfect alternative. Here are some of the more common Diskpart commands to help you learn how to use Diskpart effectively.

How To Use Diskpart

If you want to use Diskpart, you need to open up a Windows command line or PowerShell terminal. Diskpart is a destructive tool, so you’ll need to open a terminal window with the right administrative privileges.

To open Diskpart in Windows, right-click your Windows Start menu button and click Windows PowerShell (Admin) .

In your admin-level PowerShell terminal (or similar Windows command line), type diskpart and hit enter.

We’ll explore some of the most common Diskpart commands in this article, but if you want to quickly see the full list of available Diskpart commands, type help at the “DISKPART>” prompt and hit enter.

Listing Existing Hard Drives, Volumes & Partitions

Once Diskpart is open, the first thing you should do is check the current layout of your hard drives and attached storage.

At the “DISKPART>” prompt, type list disk and hit enter. This will list all of the available storage drives (including hard drives, USB storage, SD cards, etc.) that your PC can currently detect.

Deleting a Hard Drive Partition Or Volume Using Diskpart

A hard drive (disk) is separated into partitions, which are often the same as listed volumes. If your hard drive is separated into several partitions or volumes, and you wish to delete one, you can do that using Diskpart commands.

Type delete volume to delete the volume completely. Diskpart will confirm if the command was successful or not afterward.

Wiping a Hard Drive Completely Using Diskpart Clean

Rather than removing individual volumes or partitions on a drive, you can wipe a hard drive completely using the Diskpart clean command. You can also use this command if you’re looking to wipe a USB flash drive, ready for formatting.

You won’t be able to do this on your system drive (nor would you want to!) unless you’re using Diskpart on a Windows installation

At the “DISKPART>” prompt, select the disk you wish to wipe by typing select disk # , replacing # with your disk number. If you don’t know your disk number, type list disk first.

If you’re sure you want to wipe the disk completely (deleting all drive volumes/partitions), then type clean and hit enter. You won’t be asked for confirmation, so be sure you wish to do this before you begin.

Diskpart will confirm that the drive has been “cleaned”, ready for new partitions to be created.

Creating & Formatting New Hard Drive Partitions

With a “clean” drive, you’re ready to create a partition in the free space using the Diskpart create partition command. You can then format that new partition with a Windows-friendly file system like NTFS or FAT32 using the Diskpart format command.

Type list partition to make sure that your new partition is listed, then type select partition 1 to select it. Mark the partition as active by typing active at the “DISKPART>” prompt. This is necessary if you want to use it as a bootable drive.

To quickly format the drive with the NTFS file system, type format fs=NTFS label=Y quick. You can replace Y with any label you’d prefer to use.

Once formatted, Windows will likely assign a drive letter automatically. If it doesn’t, type assign letter Z , replacing Z with a free drive letter.

Extend a Hard Drive Volume

If you have an existing hard drive volume that doesn’t take up all of the free space on a drive, and you wish to enlarge it, Diskpart commands allow you to do that.

Diskpart has other options available, as the help command briefly explains. If you need further information on how to use Diskpart, Microsoft has further Diskpart support information available.

Using Diskpart to create, delete, clean or extend disk partitions

The diskpart is one of the oldest tools in the Windows operating system that handles a wide range of disk management jobs, such as assigning drive letters and deleting partitions.

SearchWindowsServer staff

For basic disk operations on Windows systems, administrators can use diskpart , a command-line utility that remains useful for many different drive-related jobs more than 20 years after it was released.

Microsoft included the free disk management tool in Windows starting in 1999 with the Windows 2000 operating system. Diskpart scans for newly added disks, but it can also create, delete and resize drive partitions , and assign or reassign drive letters. Diskpart also works with drive volumes, virtual hard disks and removable media such as USB flash drives.

Microsoft continues to develop diskpart, and the latest version of the utility features 38 commands. To use diskpart, you list the objects, such as disks or partitions, and then select the object to change it.

Using diskpart requires understanding data storage terminology

Diskpart use requires a basic understanding of Windows disk terminology . A basic disk is a storage device, such as hard drives, solid-state drives and USB flash drives, which you format with a Windows file system .

A basic disk can hold one or several partitions. A partition is a logical structure confined to a single disk.

A volume is a construct of the operating system that consists of one or more partitions that can span one or more disks.

Using diskpart

You should be careful when using diskpart because there is no undo function if you select the wrong object. Also, once a command is entered, even a destructive one, diskpart does not ask for confirmation before it runs. For example, if you perform an errant diskpart delete partition operation, you must use another utility, such as third-party disk management program, to recover the data or use a backup image to restore the drive.

Follow these tips to avoid issues when using diskpart:

Creating a partition using diskpart

Using diskpart to partition your disk can help increase the I/O performance of hard disks newly added to a RAID array . The documentation for many server applications, such as Exchange Server, recommends using diskpart to create the primary or extended partitions. You can use a primary partition as the system partition; you can only use an extended partition for additional logical drive assignments.

The diskpart create command makes disk partitions, volumes on a single disk or multiple disks, and virtual hard disks.

For this and all following commands, you need to open the command prompt before you run diskpart. Type cmd from the run command window from the Windows search box or the run command dialog box that you open with the Windows+R key combination.

To create a partition:

Extending a partition using diskpart

When it comes to adding space to a partition or volume, this method is superior to configuring two disks. Dynamic disk extensions only concatenate the newly added space, meaning they merely add the disk space to the end of the original partition without restriping the data.

Concatenation isolates performance within each partition and does not offer fault tolerance when the partition is configured in a RAID array. Diskpart restripes your existing data. This is beneficial when the partition is set up in a RAID array, because the existing partition data spreads across all the drives in the array, rather than just adding new space to the end, like the Disk Management utility.

To extend a partition:

Deleting a partition using diskpart

The delete command in diskpart removes dynamic disks, partitions, volumes and shadow copies. When you have multiple volumes on the disk or an unwanted partition, such as a recovery partition , this command will remove them and return them to unallocated space.

To delete a partition:

Creating a volume using diskpart

When using dynamic disks in Windows, you can create four volume types with diskpart: volume mirror, RAID-5 volume , simple volume and striped volume.

To create a simple volume :

At the DISKPART prompt, type create volume simple size=1000 (The size is in megabytes.)

Cleaning a disk using diskpart

When you have an entire disk to wipe clean, you can use the diskpart clean command to convert all the stored data into unallocated space. This operation deletes all data on the disk by writing zeros on each disk sector. Diskpart also removes all partition and volume information from the selected drive.

To clean a disk :

Other ways to use diskpart

For maintenance work that requires a bootable USB flash drive, you can use diskpart to format the partition and set up the file system on the removable drive. Administrators can also use diskpart in both the Windows Preinstallation Environment and Windows Recovery Environment to correct disk problems or set up the machine for deployment.

With the diskpart /s switch, administrators can run scripts to automate tasks associated with setting up Windows machines, such as configuring the disks for multiple systems, adding a recovery partition or wiping all data from a disk to return it to a factory state.

Sample code from the Microsoft site gives examples of how to develop a text-based script file administrators can call from diskpart and run automatically. IT workers can run several diskpart scripts, but Microsoft recommends building in a delay of 15 seconds after a script runs to prevent issues.

For an in-depth tutorial on how to use diskpart for preparing a Windows 10 system for deployment, this blog post on the SearchEnterpriseDesktop site provides detailed instructions to use diskpart with a script .

How to assign permanent letters to drives on Windows 10

You can assign drive letters manually, and in this guide, we show you how on Windows 10.

On Windows 10, when connecting a removable storage device or an internal hard drive, the system detects and assigns a drive letter automatically to make it usable. However, when reconnecting an external drive (such as a USB flash drive or SD or microSD cards), the system can end up assigning a different letter, which can be annoying.

If you want to see the same drive letter on a particular device, you can manually assign a permanent letter to any drive connected to your computer, and on Windows 10 , you can do this in at least three different ways, using Disk Management, Command Prompt, or PowerShell.

Using this approach will prevent Windows 10 from assigning a new letter or trying to set a letter already in use, which can cause conflicts. Also, it helps to select a drive letter that makes more sense to you.

In this Windows 10 guide, we walk you through several methods to manually assign a permanent letter to a drive, as long as you're connecting the drive to the same device and the letter isn't already in use.

How to assign a drive letter using Disk Management

How to assign a drive letter using command prompt, how to assign a drive letter using powershell.

To manage drive letters with the Disk Management tool, use these steps:

Once you complete these steps, the drive will permanently retain the assigned letter, even after reconnecting it. However, if you connect the drive to another device, it may receive a different letter.

While the easiest way to assign a new drive letter is to use Disk Management, you can also use DiskPart in Command Prompt to perform the same task.

To assign a drive letter using Command Prompt, use these steps:

After completing these steps, similar to Disk Management, every time you reconnect the storage to the same device, Windows 10 should assign the same letter automatically.

Alternatively, you can also use PowerShell to change a drive letter on Windows 10 using these steps:

Once you complete the steps, the drive will be accessible through File Explorer using the letter that you assigned, and Windows 10 won't try to change it.

Updated March 7, 2019: We revised this guide to make sure it's current with the latest version of Windows 10.

What Is Diskpart

How Do I Create a New Volume in Diskpart
