Media Creation Tool Error 0x80042405 0xA001B

I must be doing something wrong because I always have the update fail with some BS error like this. What are the proper steps to run this tool?

I download the tool to the desktop. I'm on an Admin account. I insert a 16GB thumb drive. I format it. I start the tool. I point it to the thumb drive. During the phase where the files are copied to the USB, I get some stupid error like this:

Why are my steps not good enough? Where is the hole in my logic? Or is this tool just written poorly. I'd like to use stronger language here as I used to have to start it all over again and burn bandwidth trying this failed endeavor over and over.

I've heard people make it work by running the tool FROM the USB. Why would that matter? I've tried to write files to the thumb drive just after the format and before running the tool to make sure I have successful writes. Doesn't help. 

As a workaround today, I left the error up for a bit. Tried to access the thumb drive and it said it needed to be formatted AGAIN! So I did. Then I just opened the C:$Windows.~WS\Sources\Windows and copied the files to the drive by hand. Made the dang thing myself! WHO WRITES THIS STUFF??

    PCR, 

    MS has no interest on making things more efficient, that is the strategy to force us to buy new machines... :(

    Now add 25% tariffs too :(

    MSFT is trying hard enough. There are glitches along the way, but I like the new Dashboard...

    I've had the same issue as op; needed to create a USB recovery drive to resolve an issue with Windows 10 on my Surface Go.  During the process (I think during copy, near the end), it failed with same error "0x80042405 0xA001B".  I have since tried multiple combinations of:

    1. 3 different USB drives, all >16GB, all unused
    2. Different USB ports
    3. Formatted USB w/ Explorer (FAT, FAT32, NTFS)
    4. Copied exe to usb and ran
    5. Ran as administrator
    6. Tried on 2 different PCs (none of them the problem PC)

    No solution.  8 hours wasted, original problem PC still unusable.  Would be great if released software worked.  😐

    Reading through this thread and other references, I finally found the following steps that solved my issue, maybe it could help you.  I am sure some of this is duplicate work (setting a partition then formatting), but I don't care about efficiency, I care about solving the problem.

    1. Download the Media Creation Tool (MCT) to your hard drive.
    2. Insert a >16GB USB in any USB slot
    3. Use the diskpart tool to format the USB
      1. Run the tool; Windows key, then type diskpart
      2. See all your disks to know which is the USB you are after; list disk
      3. Match the size listed to your USB and select it; select disk x (x is the listed Disk #)
      4. Remove all partitions and volumes; clean
      5. Create a partition; create part primary
      6. Select the new partition; select part 1
      7. Make it the partition; active
      8. Quick format the USB as FAT32; format fs=fat32 quick
      9. Close diskpart; exit
    4. Run the MCT and create the USB boot drive
      1. Run the MCT as an administrator from your computer; right click the exe, select run as administrator and accept any prompts
      2. Select the correct options you want in the tool; e.g. for another computer, select windows options, select USB drive you just formatted
      3. Wait…. Wait…. Wait….
      4. Success.
    5. Use your newly created USB Windows 10 recovery drive as you see fit.

    Good luck
