Do not guess your controller version. Download a diagnostic utility like ChipGenius or Flash Drive Information Extractor (FDIE) . Plug in your drive, run the diagnostic, and confirm that the "Controller Part Number" explicitly says FC1178 or FC1179 .
Broad compatibility for the FC1178/1179 series, including support for various 3D Flash memory types.
Before installing Mptools V1.0.4.3, ensure your computer meets the following system requirements: Firstchip Mptools V1.0.4.3 Fc1178 Fc1179
| Feature | Description | | :--- | :--- | | | Writes zeros to every NAND cell, ignoring the existing partition table. | | Bad Block Scanning | Reads every block to identify physically damaged sectors, mapping them out as "bad." | | Capacity Setting | Allows you to set a lower capacity (e.g., forcing a 32GB drive to 16GB) to bypass bad blocks. | | Firmware Re-flashing | Rewrites the bootloader and ISP (In-System Programming) code to the controller. | | LED Settings | Customizes the behavior of the drive’s activity LED (on/off/flash frequency). | | VID/PID Modification | Changes the Vendor ID and Product ID (useful for branding or bypassing Windows driver issues). | | Serial Number Generation | Automatically generates a unique serial number for each drive. |
: Failure. This often indicates a hardware-level NAND failure or incorrect settings. Try a deeper "Scan Level." Common Issues & Troubleshooting Do not guess your controller version
This indicates that version 1.0.4.3 does not natively contain the firmware database configuration for your exact sub-variant of memory. You may need to look for a slightly newer or older version of the Firstchip MpTools suite.
Return to the main screen and click the "Start" or "Begin" button. The MPTool will begin the process of low-level formatting and rewriting the firmware. This may take several minutes. Do not disconnect the drive during this process. | | Firmware Re-flashing | Rewrites the bootloader
Firstchip is a prominent semiconductor manufacturer whose controllers are widely used by major storage brands and budget USB manufacturers alike.
: Using this tool will permanently erase all data on the USB drive.
USB flash drives are essential tools for daily data transfer, but they are highly susceptible to corruption, write-protection errors, and sudden hardware recognition failures. When a flash drive stops working, the issue is rarely a broken physical connection. Instead, it is usually a firmware corruption issue within the mass storage controller.
