    Probably the space reserved for root, 5% by default. You can change it with tune2fs. You would need to change the blue part to the real /dev path for your device.

    Code:
    sudo tune2fs -m 0 /dev/sdbx
    The inodes and journal will still consume some space, but this is true of all file-systems.

    it is filesystem overhead which is about 5% for Ext4

    You can adjust it if you want

    But do some research before you blindly do that incase you dont want to, depending on types of data storage
