If the drive is detected but the MPALL and UPTool processes fail to complete successfully, you may need to perform a before trying again. The "Phison USB 3.0 Low-Level Format Tool v3.9.0.0" performs a deep reset on the controller's physical address mapping table (also known as the FTL or Flash Translation Layer) and attempts to rebuild it by scanning all of the NAND blocks.
You will typically find this controller in popular high-capacity flash drives, such as:
Other common causes include:
drive can act as a "Human Interface Device" (HID), typing malicious commands into a computer at lightning speed the moment it is plugged in.
While it is a reliable component for data storage, it gained significant notoriety in the cybersecurity and enthusiast communities due to its susceptibility to firmware modifications and "BadUSB" exploits. Technical Specifications Phison Ps2251-07-ps2307-
Built upon an enhanced 8051 microprocessor core , executing specialized internal application firmware.
According to community resources like USBDev.ru , you need to match the firmware burner to the specific NAND flash inside the drive. If the drive is detected but the MPALL
: Reflashing requires a specific "Burner" file (BNxx.bin) and a "Firmware" file (FWxx.bin) that matches the specific NAND chip inside the drive.
