You must verify the exact Controller Vendor and Part Number before downloading software. The tool is specific to the controller, not the brand of the USB (like SanDisk or Kingston).
Even with the fixed version, you may encounter issues. Here is how to resolve them:
| Error Message | Cause | Fix |
| :--- | :--- | :--- |
| Bad Block over setting | Too many physical defects on TC58NC6623 | In settings -> Bad Block, increase "Allow Bad Block %" to 10–15% |
| Compare Flash ID fail | Wrong ISP file or corrupted NAND | Manually paste Flash ID: 98 3E 98 B3 76 F2 in the .ini file |
| Disk Write protected | Controller locked due to bad blocks | Short pins 29 & 30 of the SSS6698BA (hardware recovery – advanced) |
| Hang at Step 4 (Download ISP) | Power issue or bad USB port | Use a USB 2.0 port (lower current = stable flashing) |
| Device not found | Driver conflict | In Device Manager, uninstall “USB Mass Storage” with “Delete driver”. Then refresh. |
Search for “SMI MPTool” or “SSS6698-BA MP Tool”.

Silicon Motion’s SSS6698-BA controller, often paired with Toshiba TC58NC6623 NAND flash, is found in many budget USB 3.0 drives. These drives frequently suffer from firmware corruption, incorrect capacity detection (e.g., 8MB or 0MB), write-protection, or device not recognized issues. This paper presents a verified method to restore full functionality using a specific MPTOOL (Mass Production Tool) version and configuration parameters tailored for the TC58NC6623. A step-by-step recovery procedure, common failure points, and post-repair validation are provided.

To repair a USB flash drive with the Toshiba TC58NC6623 (also labeled as SSS6698-BA
) controller, you typically need the 3S (Solid State Systems) MPTool (Mass Production Tool). This specific controller is commonly found in Kingston and Toshiba drives. 1. Identify Your Hardware Details Before flashing, use a utility like ChipGenius Flash Drive Information Extractor
to confirm your specific Flash ID (FID) and controller revision. Controller: SSS6698-BA / TC58NC6623 Common VID/PID: 0951:1665 (Kingston) or 0930:6544 (Toshiba) www.pc-3000flash.com 2. Download the Correct MPTool Look for the 3S USB Mass Production Utility versions that specifically support the SSS6698 controller. Commonly used version: 3S MPTool v2.182 or later. If prompted for a configuration password, is a common default for 3S tools. 3. Basic Fix Steps Preparation tc58nc6623 sss6698ba mptool fixed
: If the drive is not recognized at all, you might need to put it into "Test Mode" by shorting specific pins on the flash chip to force it into a generic state. Configuration : Open the tool and load the
file that matches your flash memory type (e.g., Toshiba or Hynix MLC/TLC). Low-Level Erase : Some recommend running the U3S SafeEraseUtility
first to clear bad blocks before attempting to flash new firmware.
: Click "Start" in the MPTool. If successful, the status bar will turn green, and the drive will be re-partitioned and formatted. Important Precautions : This process performs a low-level format and destroys all data on the drive. Firmware Mismatch
: Using the wrong firmware version can permanently "brick" the controller. OS Compatibility : These tools often require Windows 7 or XP
to run correctly; they may fail on Windows 10/11 due to driver signature enforcement. for a specific version of the MPTool? My Flash-Device - USBDev.ru
The TC58NC6623 and SSS6698-BA identify a specific USB flash drive controller manufactured by Solid State System (3S), commonly found in Toshiba TransMemory and certain Kingston DataTraveler drives. Repairing these drives when they show "No Media" or "Write Protected" requires a specialized Mass Production Tool (MPTool) to reflash the firmware. Identification and Requirements
Before attempting a fix, verify your drive's internal hardware using a tool like Flash Drive Information Extractor or ChipGenius.
Controller: TC58NC6623 (Toshiba part number) or SSS6698-BA (3S part number). Target Device: Typically 8GB–32GB USB 2.0 flash drives.
MPTool Version: The most compatible utility is usually 3S USB Mass Production Utility ver 3.287 or similar. Repair Process using MPTool
Reflashing the firmware will permanently erase all data on the drive. You must verify the exact Controller Vendor and
Download the Tool: Locate the 3S USB MPTool specifically for the SSS6698/TC58NC6623 controller from reputable repositories like USBDev.ru.
Configuration: Open the utility and select the appropriate .INI configuration file that matches your flash memory's ID (FID).
Safe Erase (Optional but Recommended): Use the U3S SafeEraseUtility (password: 5526568) to clear existing bad blocks before reflashing.
Flash Firmware: Connect the drive, wait for the tool to detect it, and click Start to begin the mass production process. This re-initializes the NAND and recreates the partition. Common Issues
Missing Binaries: These controllers often lack public binary (.BIN) files. If the MPTool does not include a specific firmware file for your NAND chip, the repair may fail.
"No Media" Status: If the tool cannot detect the drive at all, you may need to enter "test mode" by shorting specific pins on the controller chip (advanced users only).
For simpler software-level corruption, you can try Windows' built-in CHKDSK command or the diskpart "clean" command before resorting to firmware flashing. SSS [Solid State System] - USBDev.ru
The journey to reviving a "dead" USB drive using the TC58NC6623 (also known as the SSS6698-BA
) controller is a classic tale of digital archeology. It usually begins with a flash drive that suddenly shows "No Media" or becomes write-protected, leaving the user with a useless piece of plastic and metal. The Search for the Solution
The story starts with a diagnostic tool like ChipGenius, which acts as the "X-ray" for the broken device. It reveals the hidden identity of the internal chip: the Solid State System (SSS) 6698-BA
controller. With this specific ID, the user embarks on a hunt through specialized firmware forums and "foreign" tech repositories to find the holy grail—the 3S USB Mass Production Tool (MPTool). The "Fixed" Moment Even with the fixed version, you may encounter issues
Using the 3S MPTool (specifically versions like v2.084), the user enters the "Mass Production" phase:
The Connection: The tool detects the corrupted drive, often displaying a red or blank status until the correct configuration is loaded.
The Flash: The software performs a low-level format, clearing bad blocks on the NAND memory and reinstalling the firmware.
The Result: After a tense progress bar, the tool flashes green. The drive is "fixed"—reborn with its original VID/PID (Vendor and Product IDs) and a fresh, usable partition. Key Resources for the Journey
For those looking to replicate this "fixed" status, these resources are often the roadmap:
3S USB MPTool v2.084: A common utility used to re-flash SSS controllers found on sites like Flash Drive Repair.
Low-Level Guides: Technical blogs like USB-Fix provide the specific "OnCard Sorting" instructions recommended by experts for 3S chips.
CMD Alternatives: If the hardware isn't fully corrupted, some users find success with simpler commands like attributes disk clear readonly in Diskpart.
Title: Guide: Fixing and Recovering the TC58NC6623/SSS6698BA USB Flash Drive (MPTool Solutions)
If you are reading this, your USB flash drive is likely showing the dreaded "No Media" error, 0 bytes capacity, or is not being recognized by Windows. You've identified the controller as TC58NC6623 or SSS6698BA, and you are looking for the "fixed" MPTool to repair it.
This guide covers how to safely recover your drive using the correct tools and procedures.
| Error in MPTOOL | Cause | Fix |
|----------------|-------|-----|
| Pretest Fail: No supported Flash | Wrong INI or NAND ID mismatch | Manually enter NAND ID from ChipGenius (0x98,0x3C,0x98,...) in Flash database |
| ISP Download Fail | Incorrect ISP version | Use SM3268AB ISP TLC 16K, not SM3267 version |
| Device removed | Power drop | Use USB 3.0 port with dedicated power; add 10µF cap across VBUS-GND |
| Bad block count >1000 | NAND physically failing | Set capacity lower (e.g., 32GB from 64GB) and skip bad blocks |
