You might wonder why anyone still uses a tool released years ago. The answer lies in the lifecycle of USB drives. Millions of Phison-based USB drives were sold between 2014 and 2019 – from brands like Kingston DataTraveler, Corsair Flash Voyager, Patriot Memory, and PNY.

Try changing the "Host Port" setting between 2.0 and 3.0, plugging the drive into a different USB port, or enabling the "No Mapping" option before restarting the tool. | | ID ISSUE 0002 | A common error when attempting to reformat official Windows installation USBs. It often indicates a mismatch between the drive's information and the settings in the tool. Double-check your VID/PID (e.g., setting them to 13FE/5500 for Phison reference) and ensure you are using a compatible firmware set. | | Read Error / Bad Block | The NAND memory has physically degraded sectors. The tool will often map these out during the format. If the drive is old, its lifespan may be ending. The tool's "Erase" function can help but is not a guaranteed fix for failing hardware. | | Tool Crashes or Stalls | This can happen for unknown reasons. Try unplugging and re-plugging the drive, clicking "Update" to refresh the list, and starting the process again. Also, ensure you are running the tool as Administrator on a clean Windows system. |
