Hi, Since you had access denied when performing DISKPART clean/format, It means that the storage device is considered to be blocked, write-protected or unauthorized and in this case, DISKPART clean or format command cannot be properly completed. Can you please check again if your device is not locked? ---

it seem like a big problem with is tool just after failed flash your device is gone. In Poweriso when you encounter a such a problem, there is away to restore back your device to its previous state. You have to find a way to solve this issue. ---

Hi @fasegame, Are you able to run `diskpart.exe`using administrator privileges? Admin privileges are required to write onto the disk. You may follow the guide on how to run diskpart with admin privileges using this guide: [Etcher broke my USB stick … or did it?](https://www.balena.io/blog/did-etcher-break-my-usb-sd-card/#:~:text=or%20SD%20Card-,Using%20Windows,-The%20method%20you) You may also run the command `detail disk` from within diskpart after selecting the disk to see if the disk’s `read-only` property is set to `Yes`. If it is, you may try running the command `attributes disk clear readonly` in diskpart to reset that property. Reboot your computer then try reformatting your USB again. Regards, Carlo ---
