In the same Device Manager window, right-click the device and select Uninstall device . Unplug the USB, restart your computer, and plug it back in. Windows will attempt to reinstall the driver automatically.
When a flash drive degrades to a generic "Nand Usb2disk Usb Device" status, any data residing on the drive becomes structurally fragmented and unreachable by typical commercial data recovery software. If the data on the device is irreplaceable, . Flashing overwrites the memory registers completely. Instead, you must consult a professional clean-room data recovery service capable of physically desoldering the NAND chip from the circuit board to read the raw hex dumps. If the data is backed up elsewhere, using the low-level vendor MP tools remains the most effective method to restore your hardware to working order.
Do you need to off it, or do you just want the drive to work again?
Does the drive show up with or as 0 Bytes / No Media in Disk Management? Driver Nand Usb2disk Usb Device
Before diving into advanced technical procedures, it is crucial to perform a systematic hardware and software check. This can resolve the problem quickly if the cause is simple.
If none of the above steps work, the NAND flash memory itself may be damaged or dead.
: The controller chip on the drive may have physically failed. Fake Flash Drives In the same Device Manager window, right-click the
The term appears when:
When a USB drive functions normally, the controller communicates the drive's commercial identity (like "SanDisk Cruzer" or "Kingston DataTraveler") to your operating system. If Windows labels your drive as "Nand Usb2disk", it means the computer can only see the raw, generic hardware components. The operating system cannot read the drive's firmware, partition table, or file system. Common Causes of the Error
Description: [E:]USB Mass Storage Device(NAND USB2DISK) Device Type: Mass Storage Device Protocol Version: USB 2.00 Current Speed: High Speed VID = FFFF, PID = 1201 Device Revision: 0000 Manufacturer: NAND Product Model: USB2DISK Product Revision: 0.00 Controller Vendor: FirstChip Controller Part-Number: FC1178BC Flash ID code: 453E9803766C - SanDisk - 1CE/Single Channel [TLC] -> Total Capacity = 64 GB When a flash drive degrades to a generic
Many errors are fixed by completely removing and reinstalling:
Outdated motherboard drivers can cause communication breakdowns with newer or older USB chips. Open .
: Some inexpensive drives are programmed to report a larger capacity (like 2TB) than they actually have. When you exceed their real capacity, they often "brick" and show generic names. Step 1: Basic Hardware Checks
If the device belongs to a specific manufacturer (e.g., Fujitsu), check their official website for firmware or driver updates.
The device identifier " NAND USB2DISK USB Device " often indicates a low-level hardware issue where the USB controller is being detected, but the underlying NAND flash memory chip is failing or disconnected. This frequently results in the drive showing as "No Media" or "0 Bytes" in Disk Management. Troubleshooting and Driver Restoration
