Look for Vendor ID 058F and Product ID 6366 or 6371 .
This tool is designed for the AU6366 and AU6371 series of controllers, which are common in older USB drives and internal laptop card readers.
The verified tool (often version 2.1.xx or higher) automatically detects the difference and loads the correct firmware.
A tool has been submitted to communities like USBDev.ru , FlashBoot.ru , or Reddit r/datarecovery and cross-checked against original Alcor SDK releases. Verification includes:
The tool should scan and display your flash drive's information, including the model, capacity, and serial number.
: It performs deep formatting to bypass file system corruption, effectively resetting the drive's software.
If any test fails, rerun the tool with "Low Level Format" enabled. If still failing, the NAND flash may be physically dead.
