No. Silicon Power does not provide public formatter tools. They expect you to RMA the drive (Silicon Power has a good warranty policy). However, due to shipping costs and data privacy, most users prefer the low-level fix above.
Note: If you contact SP support, they may send you a private tool called SP_Recovery_Tool.exe – but for the 2021 PS2251-16, their internal tool is just a rebranded MPALL v3.86.

For users looking to repair or format a Silicon Power USB drive using the Phison PS2251
controller series (which includes the PS2251-162 / 16-2 chipset), the primary tool used is the Formatter Silicon Power v3.7.0.0. This utility is specifically designed to address common issues such as write-protection, incorrect capacity, and firmware-level glitches. Silicon Power Formatter Overview
The Formatter Silicon Power v3.7.0.0 is an end-user utility that performs both low-level and high-level formatting (FAT or NTFS).
Target Hardware: Designed for Phison-based controllers, particularly the PS2251 series. Primary Functions: However, due to shipping costs and data privacy,
Low-Level Formatting: Can reset the drive's internal structure to factory defaults, often bypassing software-based write protection.
Capacity Correction: Fixes drives showing 0MB or significantly reduced storage space.
Virus/Corruption Cleanup: Effective for cleaning drives that cannot be formatted through standard Windows or Mac OS tools. General Usage Procedure
To use the tool effectively on compatible 2021-era hardware, follow these general steps:
Preparation: Download and extract the utility. Run as Administrator and disable active antivirus software, as low-level formatting tools are often flagged as suspicious. (likely PS2251-07 or similar) | | Flash Type
Detection: Plug in the Silicon Power drive. The tool should automatically detect the controller type. If it shows "Device not found," ensure the drive is using a Phison PS2251 variant.
Formatting: Click the "Format" or "Restore" button. This process will erase all data permanently.
Verification: Once completed, re-plug the drive to verify that it is recognized correctly by the operating system. Alternative Tools for Maintenance
SP Toolbox: For standard maintenance, Silicon Power provides the SP Toolbox, which allows users to view drive health, S.M.A.R.T. status, and perform diagnostic scans without a destructive format.
Recuva: Silicon Power also suggests Recuva for standard file recovery if the drive is physically functional but data has been accidentally deleted.
Phison Restore Tool: General Phison-based drives may also use the broader "Phison Format & Restore" utility (e.g., version 3.26.0.0) for the most recent PS2251-XX models.
