Early revisions of the PS2307 firmware had no temperature throttle. The controller would run at full speed until the NAND flash's solder joints began to reflow (soften). Later firmware added throttling, but it is reactive, not preventative. By the time the throttle kicks in, the drive is already dangerously hot.
An overheating Phison PS2251-07 (PS2307) USB drive often indicates a firmware loop or hardware short, requiring firmware reflashing via tools like MPALL or specialized data recovery if the device is undetected. If the drive is extremely hot to the touch, it signifies a likely permanent hardware failure.

This controller supports capacities from 1GB to 64GB and uses advanced Error Correction Code (ECC) to maintain data integrity. However, it is an older 8051-based architecture that can struggle with sustained write operations. The "Hot" Factor: Early revisions of the PS2307 firmware had no
In cases of sector instability causing high controller load, use the "Preformat" option in MPALL to slightly lower the "Target Capacity" (e.g., set a 4GB drive to 3200MB) to stabilize the hardware. Next Steps: To help you further, could you specify: By the time the throttle kicks in, the
