How to Format a Drive in Windows 10 Using Disk Management & DiskPart

This tutorial takes about 5 minutes to complete.

Step 1: Backup and Connect Drive

Backup all important data from the target drive before making any changes. Connect any USB flash drives or external SSDs to your computer if you plan to format removable storage.

Step 2: Open Disk Management

Type Disk Management into the Windows search box and select Create and Format Hard Disk Partitions. Locate the specific disk you intend to modify within the main window.

Step 3: Initiate Standard Format

Right-click the target drive entry and choose the format option from the context menu. This opens the formatting dialog where you can configure the drive settings.

Step 4: Configure Formatting Options

Enter your desired volume label and leave the file system set to NTFS with the default allocation unit size. Ensure the Quick Format box is checked before clicking OK to proceed.

Step 5: Confirm and Resolve Prompts

Acknowledge the warning that all data will be erased and verify you selected the correct drive before confirming. If a message states the volume is in use, click Yes to allow the operation to continue.

Step 6: Launch Elevated Command Prompt

If the format option is grayed out for your target partition, type CMD into the Windows search box and click Run as Administrator. Accept the User Account Control prompt to open the required elevated command window.

Step 7: Identify Disk and Start DiskPart

Return to Disk Management to confirm the exact disk number you need to format. In the command prompt, type diskpart and press Enter to launch the utility and list all connected drives.

Step 8: Wipe and Create Partition

Type select disk X replacing X with your confirmed disk number and press Enter to verify selection. Follow this by typing clean to remove all partitions, then enter create partition primary to establish a fresh partition.

Step 9: Format and Assign Letter

Type format fs=NTFS quick and press Enter to complete the file system formatting process. Finally, enter assign to allocate a new drive letter, then verify the healthy partition status in Disk Management.
