First, a critical revelation: The TC58NC6623 is not a standalone controller. In 99% of cases, this string appears in tools like ChipGenius or USBDeview when the USB drive uses a Silicon Motion (SMI) controller, specifically the SSS6698-BA.

Why the confusion? TC58NC6623 was originally a Toshiba (now Kioxia) part number for an early USB 3.0 controller. However, SMI licensed, cloned, or rebranded this design. When you see "TC58NC6623" in Windows, the actual silicon underneath is almost always an SMI SSS6698-BA. tc58nc6623 sss6698ba mptool work

To perform successful "MPTOOL work," you must target the SSS6698-BA using SMI’s toolset. Using generic USB tools will fail. First, a critical revelation: The TC58NC6623 is not

If you have a drive with this controller and want to try repairing it (e.g., "0 MB capacity" or "Write protected"), follow this procedure: To perform successful "MPTOOL work," you must target

If you are holding a modern Toshiba (now Kioxia) drive with the TC58NC6623 controller, you have likely discovered that standard formatting tools do nothing. You have entered the purgatory of "Controller ROM Mode."

Today, we are going to talk about fixing that using the SSS6698-BA MP Tool (Mass Production Tool).
