Well I not on a windows machine at the second so I can't look at the Platform SDK. But I'm pretty sure you are looking for EnumDevices() or something like that.

Okay, ignore my ramblings That is completely wrong. I'm taking a look on msdn to see what is available.

Ah here we go:

BOOL GetVolumeInformation(
  LPCTSTR lpRootPathName,
  LPTSTR lpVolumeNameBuffer,
  DWORD nVolumeNameSize,
  LPDWORD lpVolumeSerialNumber,
  LPDWORD lpMaximumComponentLength,
  LPDWORD lpFileSystemFlags,
  LPTSTR lpFileSystemNameBuffer,
  DWORD nFileSystemNameSize
);

Enjoy!

code:----------------------------------------------------------------------------
BOOL GetVolumeInformation(
LPCTSTR lpRootPathName,
LPTSTR lpVolumeNameBuffer,
DWORD nVolumeNameSize,
LPDWORD lpVolumeSerialNumber,
LPDWORD lpMaximumComponentLength,
LPDWORD lpFileSystemFlags,
LPTSTR lpFileSystemNameBuffer,
DWORD nFileSystemNameSize
);
--------------------------------------------------------------------------------


But GetVolumeInformation() works for partitions just like C:, D:, and so on.....

Does it gives hard drive's serial number or partition's serial number ?

Judging by the 4th parameter of the function; yes, it does. You could try looking it up on MSDN.
