Repairing a Silicon Power V3700 with a PS2251 controller requires patience and the right software. By using the Phison MPALL formatter and configuring it to manage bad blocks effectively, you can restore your USB drive to a usable state.
While this process fixes the firmware, remember that if the drive failed once due to bad memory blocks, it is not recommended to store critical data on it without a backup. Use it for file transfers, but keep your most precious memories elsewhere.
