The TC58NC6623 is a rebadged version of the Solid State System (SSS) 6698-BA controller, commonly found in Toshiba flash drives like the TransMemory series. Repairing these drives often requires an MPTool (Mass Production Tool), which can re-flash corrupted firmware and isolate bad NAND blocks. Controller Identification
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
In many SSS MPTools, the process is called "Sorting." This optimizes the way data is distributed across the memory chips to ensure maximum capacity and speed based on the current health of the NAND. Common MPTool Versions for SSS6698 The TC58NC6623 is a rebadged version of the
3S USB Mass Production Utility (ver 3.287 or higher): This version is known to have some level of support for the SSS6698 series. Unlike older SM3257 or SM3267 controllers, the TC58NC6623:
Look for the Controller Part-Number. It should explicitly state TC58NC6623 or SSS6698-BA.
To repair a USB drive using the TC58NC6623 controller (which is a rebranded Solid State Systems SSS6698-BA ), you must use a specific Mass Production Tool (MPTool) to re-flash the firmware.
