Problem with DeviceIoControl function

finixfinix usaPosts: 1

This is my code:

Code:
HANDLE HandelUsb= CreateFile(L"\\.\G:", GENERIC_READ | GENERIC_WRITE, FILE_SHARE_WRITE, NULL, OPEN_EXISTING, 0, NULL);
if (HandelUsb == INVALID_HANDLE_VALUE)
{
printf("Terminal failure: Unable to open usb ERROR CODE:0x%x\n", GetLastError());
return 1;
}

    DISK_GEOMETRY d = { 0 };
    DWORD dwReturned = 0;

    int gs =DeviceIoControl(HandelUsb, IOCTL_DISK_GET_DRIVE_GEOMETRY, NULL, 0, &d, sizeof(DISK_GEOMETRY),&dwReturned, NULL);
    printf("%d\n", gs);

    if (d.MediaType == RemovableMedia)
    {
        DWORD dwReturned2 = 0;
        MEDIA_SERIAL_NUMBER_DATA data={ 0 };
        if (DeviceIoControl(HandelUsb, IOCTL_STORAGE_GET_MEDIA_SERIAL_NUMBER, NULL, 0, &data,sizeof(MEDIA_SERIAL_NUMBER_DATA), &dwReturned2, NULL)) {
                printf("SerialNumberLength %d\nResult %d\nReserved[2] %s\nSerialNumberData[1] %s ", data.SerialNumberLength, data.Result, data.Reserved, data.SerialNumberData);
        }
        else {
                printf("faild to get serial number ERROR CODE:0x%x\n", GetLastError());

        }
    }

    CloseHandle(HandelUsb);
    return 0;

Everything works well except for the function
Code:
DeviceIoControl(HandelUsb, IOCTL_STORAGE_GET_MEDIA_SERIAL_NUMBER, NULL, 0, &data,sizeof(MEDIA_SERIAL_NUMBER_DATA), &dwReturned2, NULL)
It always fails (returns a value of 0), GetLastError returns the value 0X1 (problem function).

Maybe someone here can show me what I'm missing here?

  • I ran Windus 7
  • i tried to Change the permissions function CreateFile (Add GENERIC_EXECUTE , replace to GENERIC_ALL add FILE_ATTRIBUTE_NORMAL ), play with the parameters of the DeviceIoControl.
