How to differentiate a floppy drive and a USB drive in VC++?

[code663]

Hi, how to differentiate a floppy drive and a USB drive in VC++ , i used GetDriveType and both have REMOVABLE property , and can some one explain how exactly to use "SetupDiGetDeviceRegistryProperty" to determine whether it's USB or FLOPPY

you could also use windows registry entry and settings to fetch values for hardware devices. :)

You can issue the IOCTL_STORAGE_GET_MEDIA_TYPES_EX to differentiate. Here is an example code:

//////////////////////////////////////////

DWORD dwOutBytes;
HANDLE hDevice = CreateFile(_T("\\\\.\\A:"), GENERIC_READ, FILE_SHARE_READ | FILE_SHARE_WRITE, NULL, OPEN_EXISTING, 0, NULL);

if (hDevice != INVALID_HANDLE_VALUE)
{
DEVICE_MEDIA_INFO dmi;
DeviceIoControl(hDevice,
IOCTL_STORAGE_GET_MEDIA_TYPES_EX,
NULL, 0,
&dmi, sizeof(dmi),
dwOutBytes,
NULL);

if ((MEDIA\_TYPE)dmi.RemovableDiskInfo.MediaType == RemovableMedia)
{
    //USB disk
}
else
{
    //Floppy
}

}

CloseHandle(hDevice);

Hope it is useful to you.
