请问：怎样读硬盘序列号？

笨办法:
读磁盘逻辑0扇区的0x43处,4个字节.

我记得好象有个API函数可直接得到,但忘了.

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
);

//获得硬盘各盘的序列号，不知道是不是你想要的
