    Stop EFI partition from USB drive having a letter assigned?


    Hello, when i plugin my USB drive which has some EFI partition on it, Windows 10 automatically assign it a letter which is annoying as you guess (can't access, being asked to format, etc..); how do i stop this from happening? Neither in diskpart, neither with 3rd party apps i could prevent that from happening.. ;/

    And what kind of USB drive? Thumb drives generally come formatted as FAT32, USB HDDs can be one of several formats, usually NTFS but my latest 4TB drives are exFAT.
