The journey to reviving a "dead" USB drive using the (also known as the SSS6698-BA
The SSS6698-BA is a single-channel USB 3.0 NAND flash controller from Silicon Motion. It supports several NAND vendors, including Toshiba (now Kioxia). The TC58NC6623 marking typically indicates a Toshiba 3D TLC NAND die. In mass production, these drives are initialized by vendors using an MPTOOL. When firmware metadata is corrupted — due to unsafe ejection, voltage fluctuation, or bad blocks — the controller enters a factory mode or reports incorrect parameters. Users then see:
The results were nothing short of miraculous. The crashes stopped, data loss became a thing of the past, and users could once again rely on MPTool to get their work done. The team's dedication had paid off.
If you’ve plugged in your USB drive only to be met with "Device not recognized," "Disk is write-protected," or a generic "No Media" error, you are likely dealing with a corrupted controller firmware. For drives utilizing the (which is often a rebranded SSS6698BA controller), the solution lies in using a Mass Production Tool (MPTool).
Even with the fixed version, you may encounter issues. Here is how to resolve them:
