The MPTOOL operates at the firmware level. Standard Windows formatting ( format fs=ntfs quick ) or DiskPart cleaning does not touch the controller's internal firmware. The MPTOOL does. You will need it for: tc58nc6623 sss6698-ba mptool
This controller does not support standard SMI MPTool (e.g., SM32xT). It requires a forked version often labeled SSS6698-BA_MPTool_v2.x.x.x or integrated into Toshiba_U3_MPTool . or ISP file provided with the tool download
The is a USB 3.0 Flash Drive Controller manufactured by Toshiba (now Kioxia). The specific variant, SSS6698-BA , falls under the Silicon Motion (SMI) licensing/binning tree. While SMI typically produces the SM32xx series, the SSS66xx series (SSS = "Super Silicon") represents older or licensed IP blocks, often rebranded for Toshiba’s internal use. Standard Windows formatting ( format fs=ntfs quick )
Windows cannot "talk" to a raw NAND flash device. It relies on a translation layer (FTL) stored in the controller’s firmware. When that firmware is corrupted, the drive becomes a brick. The MPTOOL bypasses Windows’ driver stack and communicates directly with the USB controller in a hardware debugging mode.
