Before downloading software, you need to be certain of your hardware. The is a controller chip manufactured by Solid State System (SSS) but frequently found in Toshiba-branded or generic OEM drives. In the world of flash drive repair, this is functionally identical to the SSS6698BA .
Select "Auto" or the specific NAND flash detected. 3. Running the Flash Process Click OK to close the settings. Press the Start button (or press F1).
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. tc58nc6623 sss6698ba mptool fixed
The Flash ID is the most critical piece of information—it tells you which ISP (firmware) file you’ll need during the MP Tool process.
If successful, it formats the drive and assigns a new, healthy partition. Important Considerations Data Loss: Before downloading software, you need to be certain
If you only need the data (not the drive itself):
Click or "Run" to begin the mass production/flashing process. Select "Auto" or the specific NAND flash detected
What is the of the drive? (Found via ChipGenius) What operating system are you using to run the tool?
Even if you think you know the chip, verify it.
If successful, the box will turn and say "OK" or "Pass." Troubleshooting Common Errors
The controller is completely locked up or drawing incorrect power. Try moving the USB drive to a rear motherboard USB port if you are on a desktop PC, or utilize a USB 2.0 hub.
