U disk prompt: write-protected. Please cancel write protection or use another disk.

Check whether your USB flash drive has a write protection switch. If there is, turn it off.

If you don't open the software in the computer system that may lock the USB flash drive, then cancel this locking function. For example, the anti-virus software of U disk usually turns on the immune function of U disk to prevent U disk of unknown origin from being displayed in the system. As long as this function is cancelled or this USB flash drive is included in the kill-free list, it can be used normally.

If your USB flash drive is write-protected, only the related folders or files in the USB flash drive are write-protected, then the problem is not the cause of the USB flash drive, but the cause of the system settings. At this point, you only need to disinfect the system once, and then change the properties of the folder or file.
