    [RESOLVED] Find device partition type

    Is there any way to know what type is a HDD device ? I need to test if a HDD partition has a specific type: NTFS, or FAT32 or EXFAT.

    From my researches I read that there is a structure that can be filled with this information: FILE_SYSTEM_RECOGNITION_STRUCTURE, taken from here: https://docs.microsoft.com/en-us/win...em-recognition But I don't know how to fill this structure: FILE_SYSTEM_RECOGNITION_STRUCTURE. Is there another way to achieve this information ?

    And where did you read that this struct contains any value that points to the type of a HDD device?
    typedef struct _FILE_SYSTEM_RECOGNITION_STRUCTURE {
    UCHAR Jmp[3];
    UCHAR FsName[8];
    UCHAR MustBeZero[5];
    ULONG Identifier;
    USHORT Length;
    USHORT Checksum;
    } FILE_SYSTEM_RECOGNITION_STRUCTURE;

    Use WMI, it gives drive info plus a whole lot more.

    Given the root directory name for the required device, use GetVolumeInformation(). The name of the type of format is returned via lpFileSystemNameBuffer.
