Every USB drive contains a tiny microcontroller chip (the "brain") and NAND flash memory (the "storage"). If the controller firmware crashes or enters a panic state, it locks the memory chips into a permanent read-only mode to safeguard data. Standard formatters cannot communicate with the microcontroller to reset this status. 3. NAND Flash Wear and Bad Sectors
Unplugging a drive while the controller is actively writing data is the number one cause of firmware corruption. Always click "Eject" in your system tray. mxt usb device format tool

Flash drives are meant for data transport, not permanent storage. Always keep a secondary copy of critical files on a cloud drive or physical external hard drive. Do you need to from it first, or just fix the hardware
