Formatter Silicon Power: V.3.7.0.0 -ps2251-.162

Proceed with caution. The low-level format will strip the partition signature. You must rebuild the boot sector manually using bootsect /nt60 afterward. Conclusion The string "Formatter Silicon Power v.3.7.0.0 -PS2251-.162" represents a specific rescue algorithm for a specific controller generation. It is not a magic bullet for every USB drive, but for Silicon Power drives built around the Phison PS2251-62 chipset, it is the only consumer-accessible tool that speaks the drive's native language.

No. Modern flash drives (even cheap ones) cost less than $10. The controller on a 16GB drive is often held together by cheap solder. If the formatter fails once, the NAND has likely reached its write-cycle limit (approx. 3,000 P/E cycles). Recycle the drive. Formatter Silicon Power v.3.7.0.0 -PS2251-.162

If you followed the guide correctly and still see an error, accept that the NAND flash memory has physically degraded. However, for 90% of users who land here—those with a drive that identifies as a "PS2251-62" but refuses to format—this utility will restore full functionality. Proceed with caution
