Type list disk to see all connected drives. Identify your USB (usually Disk 1 or Disk 2). Type select disk X (Replace X with your USB's number).

• Windows: USB Flash Drive Recovery tools, ChipGenius (identify controller), manufacturer reformat tools.
• Linux: Test with lsusb; use smartctl (if supported) or dmesg to view errors.
• Fake-capacity devices: Use F3 (Fight Flash Fraud) on Linux/macOS or h2testw on Windows to detect and restore actual capacity. For fake devices, reformatting can't fix fraudulent firmware — return/refund.

• Examples: ChipGenius, SMI MPTool, Phison MPTool.
• Function: These interact directly with the USB controller firmware. They can perform a "factory reset," rebuild firmware, and correct capacity errors.
• Verdict: High risk. Requires technical knowledge to identify the specific Controller Vendor ID (VID) and Product ID (PID). Using the wrong tool will brick the device.
