BOOL GetVolumeInformation(

LPCTSTR lpRootPathName, // address of root directory of the file system
LPTSTR lpVolumeNameBuffer, // address of name of the volume
DWORD nVolumeNameSize, // length of lpVolumeNameBuffer
LPDWORD lpVolumeSerialNumber, // address of volume serial number
LPDWORD lpMaximumComponentLength, // address of system's maximum filename length
LPDWORD lpFileSystemFlags, // address of file system flags
LPTSTR lpFileSystemNameBuffer, // address of name of file system
DWORD nFileSystemNameSize // length of lpFileSystemNameBuffer
);

4. int main(int argc, char* argv[])
5. {
6.     char buff[1024];
7.     GetVolumeInformation("C:\\", buff, sizeof(buff)/sizeof(char), 0, 0, 0, 0, 0);
8.     printf("%s", buff);
9.     Sleep(5000);

invoke GetVolumeInformation, offset disk, 0, 0, 0, 0, 0, 0, 0
