Tc58nc6623 Sss6698ba Mptool | Work
| Problem | Solution |
|---------|----------|
| Tool sees 0MB / Bad Block > 100% | NAND ID mismatch – correct FlashList.dat or use forced ID via uDiskToolBar |
| Error: "Download ISP Fail" | Wrong ISP version – try ISP from SM3268AB_TC58NC6623 pack |
| Error: "Compare Fail at 0xXXX" | Bad NAND (replace chip) or poor soldering |
| Drive not detected after short | Use USB 2.0 port; remove battery from laptop; try different short point (D-/D+ to VSS) |
| MPTool crashes on Win10 | Run in Windows 7 compatibility + Administrator |
Once the MPTOOL reports success and your drive appears with the correct capacity, perform these final steps:
If you matched the NAND correctly, the progress bar will move from "Pretest" to "ISP Download" to "Format."
If the GUI settings fail, directly edit the UFD_SSD.INI file (located in the ini folder). Add or modify these lines under [FUNCTION]:
ENABLE = 1
FORCEDLOWLEVELFORMAT = 1
ERASEALLBADBLOCK = 1
IDBLOCKVERSION = 2
TESTCAPACITY = 0 ; Set to 1 to force a safe lower capacity
Then, under [OPTION], add:
SETAP = 1 (This forces Auto Production mode, bypassing many initial checks).
For 99% of users: The TC58NC6623 / SSS6698-BA cannot be repaired with public MPTools.
The controller was deliberately locked by Toshiba/Kingston to prevent third-party reflashing. Unlike older SM3257 or SM3267 controllers, the TC58NC6623: tc58nc6623 sss6698ba mptool work
| Parameter | Value |
|-----------|-------|
| Controller | TC58NC6623 = SSS 6698-BA |
| Best tool | SM3268AB_TC58NC6623_MP_v2.5.59_v3 |
| Key file to edit | FlashList.dat |
| ISP type | TSOP48 15nm (Toshiba) |
| Debug switch | /d + ENABLE=1 |
| Success rate (good NAND) | ~85% |
Final recommendation:
Use the SM3268AB_TC58NC6623 repack from usbdev.ru (search for post #71289).
Do not mix with Innostor or Alcor tools – this is strictly a Skymedi family controller.

Restoring a USB drive with the Toshiba TC58NC6623 controller (also known as the SSS6698-BA
) is a technical process that involves using specific "Mass Production Tools" (MPTools) to re-flash or repair corrupted firmware. This is often necessary when a drive shows as "No Media" or "Write Protected" due to software errors in the controller. Understanding the TC58NC6623 / SSS6698-BA TC58NC6623 is a rebadged version of the Solid State Systems (SSS) 6698-BA
controller. It is commonly found in Toshiba and Kingston flash drives (like the DataTraveler series) | Problem | Solution | |---------|----------| | Tool
. Because these controllers are identical, tools designed for the SSS6698-BA are the primary solution for repairing these devices. Using the MPTool for Repair
To fix a drive with this hardware, you must use a compatible version of the 3S USB Mass Production Utility Identification
: Before starting, verify your controller details using a tool like ChipGenius . It will confirm the

or later are used to interface with the controller. These tools allow you to "sort" bad blocks or reload the firmware to make the device usable again. Configuration
: To make changes in these utilities, you often need a password; for many SSS tools, the default configuration password is The Flashing Process Run the utility and ensure it detects your drive. Access the settings using the password mentioned above. Once the MPTOOL reports success and your drive
Select the correct firmware binary (often included in the tool's folder) that matches your specific Flash ID (e.g., Toshiba TLC-8K).
Execute the "Start" or "Flash" command to rewrite the controller's internal instructions. Risks and Warnings Using an MPTool is a destructive process
