: Scans the NAND flash for physical defects and maps them out, effectively "healing" the drive at the cost of some storage space.

: Access the "Settings" (often requires switching to Chinese to avoid crashes in some older versions) to select the scan mode. Scanning : Use Standard Scan first to identify the NAND.
