“I just got a 32GB USB flash drive from my brother, formatted to be FAT32. When I was transferring a 5 GB files to it, it failed and popped up an error message saying ‘File is too large for the destination file system’. I googled it and knew that is about file size restriction. And I need to format it to NTFS to break out its 4GB size limitation on a single file. So can I use Diskpart to format NTFS in Windows computer and how to do it in detail?”

What is the use of DiskPart command?

DiskPart commands is a command-line disk partitioning utility available for Microsoft operating system. It allows you to view, create, delete, format a computer’s disk partition. Before you can use DiskPart commands, you must first list, and then select an object to give it focus. When an object has focus, any DiskPart commands you type will act on that object.

Use Diskpart to format drive to NTFS (Command Line)

Generally speaking, when Windows users fail to format hard drive to NTFS via Disk management or File Explorer and get various formatting errors like “Windows was unable to complete the format” “The format did not complete successfully” or some else, Diskpart will be an alternative. How to format disk to NTFS using Diskpart Command? Below are elaborate steps you can refer to.

Warning: formatting operation will erase everything on the drive you select. It is crucial that you correctly choose the drive you decide to format. It is always advised to back up data before proceeding.

1. Press the “Windows key + X” on your keyboard to open the Power User menu and select “Command Prompt (Admin)” to launch Command Prompt.

In Windows 7, you need to launch it in a different way: click “Start” button, input “cmd” in the “Search” box, right click the Command Prompt icon and select “Run as administrator”.

2. Type “Diskpart” in the Command Prompt and press “Enter”.

3. Then execute the following commands in sequence:

  • list disk: list all disks recognized by OS.

  • select disk 1: select the disk which contains the partition you need to format to NTFS using CMD. Here we select disk 1.

  • list partition: list all partitions on the selected disk.

  • select partition 1: select the target partition. Here we select partition 1.

  • format fs=ntfs quick: format partition to NTFS file system.

Diskpart Format Ntfs

When the formatting process is completed, you can run the “exit” command to close DiskPart.

If the hard drive is now of FAT32, and you want to format it to NTFS, you can enter Command Prompt and directly run "convert [drive letter of the target partition] : /fs:ntfs” (ex: convert e: /fs:ntfs) to convert FAT32 to NTFS without formatting/losing data.
If you want to format C drive in Command Prompt, you have to boot your computer from the installation media and perform the formatting task in WinPE mode.
