Hello,
I received a 512GB USB stick purchased on Amazon and my Windows indicates that there are 460GB free out of 460GB total.
I've lost 52GB along the way... Can someone tell me how I can get the full 512GB please?
Thank you so much :)

    Hello
    USB key connected
    Go to "Disk Management"
    Right-click on the icon in the bottom left corner of Windows and click on Disk Management
    or
    On your keyboard, press the Windows key + R
    then in the Run window, type diskmgmt.msc and finally click OK
    the Disk Management window opens
    Provide a screenshot

      Hello, here it is :)
      The USB key is visible in "This PC" as "USB Drive E:".

      Hi,
      And on top of that, the partition tables and the file systems of the partitions also take their share! Even if it's not much compared to everything else, of course.

      And to continue, the size of the sectors can cause a sector not to be fully filled, which is especially annoying with lots of small files...

      Thank you :) I might be a bit slow, but I don't understand the article.

      The seller displays a 512GB USB flash drive... So... actually... it would be less because for him 1GB = 1000MB while in reality 1GB = 1024MB.
      So... unless I'm mistaken, there is 2.34% missing in the story. (24MB represents 2.34% of 1024MB).
      But 2.34% of 512GB = 11.98GB.
      So I should have Windows showing me 512GB - 11.98GB = 500.02GB
      Right? Did I make a calculation or understanding error? Thank you ;)

      There are no files on the USB drive.

      Your key is 500 Gigabytes
      which is equivalent to 466 Gibibytes (value given by Windows)
      so everything is normal!!
