No. The drive shuts down at 100°C. ABS plastic melts at 200°C. You are safe regarding fire hazards.
: Because the controller uses a basic 8051 architectural core, handling modern USB 3.0 data rates requires the processor to run at maximum utilization. Basic tasks like Error Correction Code (ECC) calculations and wear-leveling cycles place a continuous load on the controller, driving up temperatures. The drive appears in Windows Explorer, but disappears
Before executing a programmatic repair, you must determine if your flash drive's behavior matches standard Phison thermal and firmware failure modes:
If the data lines connecting the controller to the NAND flash degrade, or if bad sectors corrupt the sector tracking tables, the controller enters a continuous, high-frequency execution loop. The 8051 core spins at maximum clock speed trying to resolve ECC (Error Correction Code) errors, pushing the controller to its maximum thermal threshold. 3. Poor Heat Dissipation Many retail flash drives package the Go to product viewer dialog for this item. You are safe regarding fire hazards
The PS2251-07 is not recommended for Windows-To-Go. Its single-channel design and poor 4K random write performance result in sluggish system operation and frequent stuttering. If you need a portable Windows drive, look for drives with PS2251-08 (PS2308) or SSD-based USB enclosures.
drive enters a firmware panic, the operating system will no longer see your storage partition. Instead, the tool will report the following hardware flags: PS2251-07(PS2307) Device Name: 2307 PRAM (or Phison PRAM Device ) Capacity: 0 MB or 0 Bytes
