Modern USB flash drives utilize NAND flash memory, which has distinct physical characteristics, including bad blocks and specific page sizes. A true "low-level format" on a USB drive today essentially resets the drive to its factory state. It involves marking bad sectors, resetting the translation layer that maps logical block addresses (LBA) to physical NAND blocks, and in some cases, updating the firmware. Unlike a high-level format, which simply clears the file allocation table, a low-level format scrapes the underlying structure of the drive.
