Phison PS2251 Data Recovery

Zero Alpha offers professional data recovery for the Phison PS2251 series USB flash controller. These controllers are commonly found in a wide range of USB drives in capacities such as 8GB, 16GB, 32GB, 64GB, and 128GB. Users often experience issues such as the drive not detecting, showing 0MB capacity, becoming write-protected, or suddenly losing access to files. We handle complex controller-level faults and NAND flash issues in-house, and we accept mail in jobs from Australia and worldwide.

Phison PS2251-06-V Data Recovery Caselog

18NOV25: The usb does not detect it just shows no media. Current PS2251 revisions implement LDPC ECC instead of legacy BCH, meaning page decoding, parity handling, and error correction are tightly coupled to the controller firmware and NAND-specific parameters. This significantly complicates raw NAND reconstruction and requires controller-aware decoding or matched firmware-level emulation for successful recovery.
