The drive controller is stuck in a boot loop panic state. You may need to manually trigger Test Mode on the physical hardware circuit board. To do this, open the USB plastic casing and use a metal pin to briefly short-circuit the data pins (typically pins 29 and 30) on the flash memory chip while plugging it into the computer port. This forces the controller into a generic programming state where the SMI MPTool can recognize it.
