:warning: Warning: Using MPTools carries significant risks.

If you found TC58NC6623 + SSS6698-BA on a drive larger than 64GB, it is almost certainly a fake capacity drive. The real hardware limit for this controller with that BA bridge is:

If your drive claims 128GB, 256GB, or 1TB, the MPTool will appear to succeed, report a "Pass," but the drive will corrupt data after the first 32GB. You are recovering a hardware-limited device. tc58nc6623 sss6698-ba mptool

If Windows detects the drive but shows 0MB, skip this. If the drive is completely unrecognized, you need ROM Mode:

If you have searched for "TC58NC6623 MPTool" and found nothing, or downloaded random "SSS6698-BA" tools that don't work, here is why:

First, understand that SSS stands for Solid State System, which was acquired by Silicon Motion, Inc. (SMI). Therefore, the SSS6698-BA is an SMI controller. The TC58NC6623 is a variant—often a Toshiba-branded part number—that utilizes the same underlying SMI 6698 architecture.

The TC58NC6623 (SSS6698-BA) MPTOOL is a powerful, dangerous, and essential piece of software. It bridges the gap between a bricked flash drive and a functioning one. The key to success is:

While the tool looks like it was designed for Windows 98, it remains the only lifeline for millions of USB drives using this controller. Use it wisely, respect the hardware limitations of TLC NAND, and always maintain a backup. With this guide, you should be able to turn that dead drive from a paperweight back into a usable storage device. Click the "Setting" or "Config" button

When a USB flash drive with the TC58NC6623 controller (often paired with SSS6698-BA

firmware) becomes "write-protected," it usually indicates a critical firmware error or that the NAND memory has reached its end-of-life and locked itself to prevent data loss. Standard Windows tools like

often fail in these cases because the lock is at the hardware level.

To "write piece" (re-flash or fix) this specific drive, you typically need a Mass Production Tool (MPTool) compatible with the Solid State System (SSS) controller family. Repair Steps for TC58NC6623 / SSS6698-BA Identify the Exact Controller : Use a tool like ChipGenius Flash Drive Information Extractor to confirm that your controller is indeed the SSS6698-BA. Download the Correct MPTool : Look for a version of the SSS MPTool that explicitly supports the series (e.g., SSS6698 B7000 or similar). Run as Administrator Inside the settings, look for these tabs:

: Open the MPTool executable. If the drive is detected, it will show up in one of the numbered slots. Configure the Tool (or use the default configuration if available). You may need to select a specific

or ISP file provided with the tool download that matches your NAND flash type (Toshiba/SanDisk/etc.). Start the Process to begin the low-level format and firmware re-write. Using an MPTool will erase all data

on the drive. If the tool returns an error like "ISP Not Found" or "Flash Not Supported," the hardware may be physically defective beyond software repair. Alternative Recovery (If MPTool Fails)

Before trying the low-level MPTool, you can attempt to clear software-level flags: : Open Command Prompt as Admin, type select disk X (your USB), and attributes disk clear readonly Registry Fix
