    This kind of problem wasn't on RS1. Could you help me to get one drive? Thanks in advance.

    What does Disk Management show? Does this particular USB have two partitions? Windows 10 Creators Update is the first edition of Windows capable of using all partitions on a flash drive, previously only the first partition could be accessed.

    May I make one partition in this situation or better leave it?

    P.s. Thanks for the information about capability of using all partitions by Win10 CU.

    17MB really is not of much use now-a-days considering a 1 minute YouTube video usually is between 2.5 and 4 MB in size. If the drive is otherwise working I'd leave it as is.

    Your Disk 3 has a single bootable partition J: (translation: Healthy (active, primary partition) ) while the 17MB at the end is show as Unallocated. You could add this unallocated space to the existing partition, but it's very small, and as I have no idea what this bootable USB is for I think it's best to leave it as it is.

    But Disk 3 only has one partition, It still doesn't explain where your K: USB drive came from. Which disk does Disk Management show as being K:? It looks like you really do have two USBs plugged in.

    Please note that the whole flash drive Dysk 3 has the drive letter K.:)

    The J: drive is shown as Multiboot. To me that indicates that this USB flash drive was formatted with a third party program and the 17MB partition is some sort of boot partition in some file format that native Windows cannot read. If it were my flash drive, I would copy everything off of it that I wanted to keep. Run the diskpart "clean" command on it, reformat the whole thing as one FAT32 or NTFS partition.

    Yup, try it for yourself. You can use Diskpart to make a few partitions on a USB :)

    And Disk Management too! Sorry I can't give you a Rep but I have to "spread it around" first!

    Only once the USB has an MBR (most don't). Diskpart can create the MBR, after that Disk Management can be used. It's Cerebus who deserves the Rep for spotting this first....
    CU supports multiple partitions on a standard USB Flash Drive
