Once you have confirmed the controller type, you can attempt a low‑level repair using the manufacturer’s .

Unplug the USB drive, wait 10 seconds, and plug it back into a different USB port to trigger a fresh hardware initialization sequence. Step 4: Reassign Drive Letters and Check Disk Management nand usb2disk usb device driver exclusive

Since these drivers are often unsigned, you may need to disable in Windows to install them: Go to Settings > Update & Security > Recovery . Under Advanced startup , click Restart now .

If the files stored on the malfunctioning drive are irreplaceable, . Standard data recovery software cannot communicate with a drive trapped in a "NAND USB2Disk" bootloader loop.

If the mass production tool fails to see

If the issue is caused by a glitching Windows driver stack, resetting your USB controllers through Device Manager can force the operating system to re-initialize the connection cleanly. Press Windows Key + X and select .
