If the drive doesn't light up, shows 0 bytes of capacity, or is completely unrecognized in Disk Management, the controller chip or a power resistor has likely suffered physical burnout. In this scenario, the only option is a professional data recovery service. They will perform a "NAND chip-off" recovery—physically desoldering the memory chip from the circuit board and reading it using a specialized hardware programmer. Conclusion
The Master Boot Record (MBR) or GUID Partition Table (GPT) on the drive has been damaged, rendering the file system unreadable.

Use ChipGenius to identify the chip and rewrite firmware using an MPTool. Driver Nand Usb2disk Usb Device
Before changing software settings, rule out basic hardware connection issues:
Locate any entries named Nand Usb2disk , Unknown USB Device , or mass storage devices marked with a purple bullet point (indicating disconnected history).
This error rarely happens without an underlying hardware or software trigger. The most frequent causes include: If the drive doesn't light up, shows 0
: Acts as the interface between the hardware (the physical USB stick) and the operating system's file system, managing tasks like logical sector reading, writing, and bad-block management.
Does it give you a specific (like Code 10 or Code 43) in Device Manager? I can give you more specific steps based on those details. Share public link
You might also see a yellow exclamation mark next to it, or a notification saying "Driver error." Don't panic. This is surprisingly common, and it doesn't necessarily mean your USB drive is dead. Conclusion The Master Boot Record (MBR) or GUID
Open (press Windows Key + X and select Disk Management) to see how Windows maps the drive.
Many generic USB drives purchased from online marketplaces are set to report a massive capacity (e.g., 2TB) even though they physically only contain a small NAND chip (e.g., 64GB). Once a user tries to write data past the physical limit, the controller can crash, leaving behind the raw generic “NAND USB2DISK” driver signature.
Run the manufacturer's recovery tool to format the drive at a low level and restore its factory identity.
