Retrieve serial number from USB memory (Windows environment c++) -

i need retrieve serial number usb memory, namely hard disk's serial number manufacturer assigns. reason cannot use getvolumeinformation() suggested in other threads. need have "unique" number

i kindly ask if can share example in c++ , windows environment (visual c++)

thanks!

you device number calling deviceiocontrol() handle device:

dword getdevicenumber( handle devicehandle ) {    storage_device_number sdn;    sdn.devicenumber = -1;    dword dwbytesreturned = 0;    if ( !deviceiocontrol( devicehandle,                           ioctl_storage_get_device_number,                           null, 0, &sdn, sizeof( sdn ),                           &dwbytesreturned, null ) )    {       // handle error - bad handle.       return u32_max;    }    return sdn.devicenumber; } 

next here method recognize if volume removable media (e.g. usb or firewire disk):

bool isremovablemedia( s32 vol ) {    char rootpath[5] = "@:\\";    rootpath[0] = (char)( vol + 'a' );     char szdosdevicename[max_path];    char dosdevicepath[3] = "@:";     // drive type    uint drivetype = getdrivetype( rootpath );     if ( drivetype != drive_removable )       return false;     dosdevicepath[0] = (char)( vol + 'a' );    querydosdevice( dosdevicepath, szdosdevicename, max_path );     if ( strstr( szdosdevicename,"\\floppy") != null )    {       // floppy       return false;    }     return true; }
