Many cheap flash drives sold online use hacked firmware to display inflated capacities (e.g., a 32GB physical chip masked to show as 1TB). Once data overwrites the true physical limits of the NAND flash, the file allocation table collapses. The controller locks down, exposing its real identity: a generic, low-cost controller chip running raw factory defaults. 3. FirstChip Controller Default Behavior

As USB4 and USB-C with proper authentication roll out, the USB-IF is tightening enforcement. However, VID FFFF PID 1201 will likely persist in:
