Differentiation between a USB drive and a USB hard drive in Windows

Question

I am trying to distinguish between a USB drive and a USB hard drive in Windows using the Win32 API.

The GetDriveType () function will return DRIVE_REMOVABLE if the drive is removable and the USB drives are, of course, removable. But I think that Windows probably also considers removable USB drives (unfortunately, I don't have access to a USB hard drive to check it out).

Thanks in advance.

//  Method      OpenVolume

//              if you just want to inquire if it removable.

    HANDLE volume = ::CreateFile(volumeName, GENERIC_READ | GENERIC_WRITE, FILE_SHARE_READ | FILE_SHARE_WRITE, NULL, OPEN_EXISTING, 0, NULL);
