If Windows-based repair methods fail, this alternative approach with GParted offers a reliable solution for unable to format a usb stick after using rufus—and it only requires a separate USB drive with Linux boot capability:

If you have another USB and can boot Linux:

  1. Create an Ubuntu bootable drive on a spare drive.

  2. Boot the faulty device into Ubuntu, selecting the non-installation trial mode.

  3. Open Software 

  4. Locate the faulty USB drive, delete all existing partitions → create a new primary partition → format to the target file system (FAT32).

Pros

  • Completely bypasses Windows system permissions or partition restrictions on USB drives, resolving the “unable to format a USB stick after using Rufus” issue that cannot be fixed within Windows.

  • The GParted tool offers professional functionality, supporting various partition formats, ensuring high compatibility for the USB drive post-formatting. 

  • Entire process is free from bundled software; the image is an official, clean version ensuring security.

Cons

  • Presents an operational barrier for complete Windows novices, requiring mastery of foundational steps like USB boot and BIOS configuration.

  • Creating the bootable drive and initiating boot sequence is time-consuming, offering lower efficiency compared to native Windows tools.

  • On older hardware, Ubuntu may experience startup lag or fail to detect the USB drive.
