If you follow this guide carefully, you have a high chance of saving your USB drive. If you fail, the drive's NAND chip has likely reached the end of its physical life—and no tool, software, or magic can fix that.
To safely identify your controller chip without physically breaking open the USB plastic casing, use a free hardware diagnostic tool called or Flash Drive Information Extractor . Download and run ChipGenius . Plug your problematic USB drive into your computer. Select your USB drive from the device list. Look at the information panel for the following fields: Controller Vendor : Solid State System (or 3S) Controller Part-Number : SSS6698 / SSS6698BB / SSS6698-B8
: Use the "Auto-Detect" or "Scan" button. If the drive is recognized, the tool will display the Flash ID and capacity. Start the Process sss6698bb format tool
Go to the tab, check Run this program as an administrator , and click Apply. Step 3: Configure the INI Initialization File
If the MPTool reports "ISP Not Found" or "Flash ID Not Supported," the issue may be a physical hardware defect (e.g., a dead NAND chip) rather than a software corruption. for a specific MPTool version? If you follow this guide carefully, you have

For the , yes, generally speaking. If the controller matches, the tool is safe. If the controller does not match, the tool usually just won't detect the drive, though there is always a minor risk when flashing firmware. Download and run ChipGenius
Be careful. This tool is specifically for . Other common variants (like SSS6691, SSS6695, or SSS6697) require different versions. Using the wrong MP Tool can permanently brick your drive.
The is a specific controller used in USB flash drives, primarily by manufacturers like Kingston. When these drives become "write-protected," show "no media," or fail to format using standard Windows or macOS tools, you need a specialized "Mass Production Tool" (MPTool) designed for that specific chip. 1.
