Almost all SD cards include a slider on the side that acts as a locking mechanism. When it’s at the bottom position, it locks the card and prevents you from changing anything on it. Eject the SD card from your device and make sure the slider is at the top, away from the Lock position.

    There are a few FORMAT programs in Windows.
    Hp Usb Disk Storage Format Tool 2.2.3
    Rufus 2.16 Beta
    Sd Card Formatter 5.0.0
    Yumi 2.0.5.1

    As well, many partition & file manager programs will allow creating & formatting MOST storage media. Usually I use GPARTED in Linux to quickly examine why the storage flash drive cannot work. This can be done with a Flashstick version of "Live" Linux, such as Xubuntu, or "Mint".

    Usually I discover that the flash storage has no partition of any kind at all. So Gparted will "see" this, and allow removal of any rubbish there, then allow creation of the partition. Some flash devices however seem to have inbuilt electronic problems, and can never be rescued, it seems.
