Subject: Guide: Restoring TC58NC6623/SSS6698BA Flash Drives Using MPTool

Standard restoration tools for SSS controllers are often available on technical repositories such as FlashBoot.ru or USBDev.ru.

Step 1: Identification (ChipGenius) Before you can fix it, you must confirm the hardware. You need a tool called ChipGenius.

1. Full Windows Format: Use diskpart → clean → create partition primary → format fs=ntfs quick.
2. CrystalDiskMark Test: Run a benchmark. The SSS6698-BA controller should deliver ~100-130 MB/s read and 20-40 MB/s write (for TLC NAND). If speeds are under 10 MB/s, you used the wrong NAND preset.
3. h2testw Verification: Fill the entire drive with data to confirm no hidden bad blocks remain. Any error means you need to rerun MPTOOL with a more conservative capacity.

If you absolutely must experiment, search for SM3268AB MPTool 2.5.70 v14 Q1106 (a rare Chinese forum release) and expect to manually patch NAND definitions for weeks.
