A: You have likely purchased a counterfeit drive. The controller is programmed to report a larger capacity (e.g., 128GB) than the physical NAND flash chip (e.g., 16GB). Use H2testw to verify the true size.
The Product ID 198A narrows things down significantly. This PID is commonly associated with used in business-class laptops and some standalone USB security keys.
