In this article, we will explore how to format a disk using the Command Prompt (CMD) in Windows 10. Formatting a disk is a crucial task when you want to prepare a storage device for use or troubleshoot disk-related issues. By aligning this topic with the Windows environment, we will provide step-by-step instructions on how to format a disk using CMD, ensuring that readers can easily follow along and apply the knowledge to their Windows 10 systems.

Examples:

1. Open Command Prompt: Press the Windows key + R to open the Run dialog box. Type "cmd" and press Enter to open the Command Prompt.

2. List available disks: In the Command Prompt, type "diskpart" and press Enter. Then, type "list disk" and press Enter to view a list of available disks on your system.

3. Select the disk: Identify the disk you want to format based on its size and type. For example, if you want to format Disk 1, type "select disk 1" and press Enter.

4. Clean the disk: To remove all partitions and data from the selected disk, type "clean" and press Enter. Be cautious as this action will permanently delete all data on the disk.

5. Create a new partition: Type "create partition primary" and press Enter to create a new primary partition on the disk.

6. Format the partition: To format the newly created partition, type "format fs=ntfs quick" and press Enter. You can replace "ntfs" with other file systems such as "fat32" if desired. The "quick" parameter performs a quick format instead of a full format.

7. Assign a drive letter: Type "assign letter=Z" and press Enter to assign a drive letter (in this example, Z) to the formatted partition.

8. Exit DiskPart: Type "exit" and press Enter to exit the DiskPart utility.

9. Exit Command Prompt: Type "exit" and press Enter to close the Command Prompt.
