Re: How do you get the number of physically installed hard disks (Win32)?

fine. you can get total number of physical drives and also the interface
name (in form guid) by calling another setup API func. Are you aware of any
function which can give me indivual device name in form of

Sounds like you remember NtQuerySystemInformation() with info class

But the IMHO recommended way to do this is the Setup API:

#include <windows.h>
#include <initguid.h>
#include <setupapi.h>
#include <devguid.h>

hDevInfoSet = SetupDiGetClassDevs(

DevInfoData.cbSize = sizeof(SP_DEVINFO_DATA);
dwDisks = 0;

while ( SetupDiEnumDeviceInfo(hDevInfoSet, dwDisks, &DevInfoData) )


BTW, you don’t have relatives in Germany, do you? It’s just that the
names translate perfectly … :wink:
