The software will map the drive to see if the advertised space matches the physical NAND reality.

The "USB Mass Storage Device (NAND USB2DISK)" identifier is a red flag. It reveals that your USB drive is a generic, low-cost device—most likely from FirstChip—with no branding or quality control. While some of these drives work adequately for temporary file transfers, they are .
