The DiskPart method can resolve 95% of instances of unable to format a usb stick after using rufus, making it the most effective approach for fixing Rufus-related USB drive formatting issues.

1.Open Command Prompt as Administrator:

  • Press Win + X → Windows PowerShell or Command Prompt

2.Run DiskPart:

diskpart

3.Identify your USB:

list disk

  • Important: Note the disk number of your USB

4.Select and clean the USB:

select disk X    (replace X with your USB disk number)

clean

⚠️ This erases everything! Double-check disk number.

5.Create new partition and format:

create partition primary

assign 

exit

This command-line operation can completely reset the partition and file system of a USB drive, fully resolving the issue where a USB drive cannot be formatted after using Rufus due to partition or file system corruption related to Rufus.
