为什么在C盘和在D盘得到的系统盘序列号不一样？

ice__man 2003-08-24 11:10:45

源代码如下：

procedure TForm1.Button1Click(Sender: TObject);
var
VolumeSerialNumber : DWORD;
MaximumComponentLength : DWORD;
FileSystemFlags : DWORD;
SerialNumber : string;
cPath : array[0..255] of char;
sPath : string;
driver : string;
begin
if GetWindowsDirectory(cPath,256)<>0 then
begin
sPath:=cPath;
driver:=ExtractFileDrive(sPath);
end
else
raise Exception.Create('System Error！');
GetVolumeInformation(PChar(driver),nil,0,@VolumeSerialNumber,
MaximumComponentLength,FileSystemFlags,nil,0);
SerialNumber := IntToHex(HiWord(VolumeSerialNumber), 4)+'-'+IntToHex(LoWord(VolumeSerialNumber),4);
Edit1.Text:=SerialNumber;
end;

为什么上面的程序在系统盘（例如：C盘）得到的是错误的，而把程序放到其他盘中，就可以得到正确的呢？

windows没有自带工具可以看到
只能使用HWinFO软件和一些专业的Sis之类的测评软件才能获得
ADIA32都可以，MyDrivers.com上有

有什么windows自带底工具可以直接看硬盘物理序列号不？
或者硬盘标签上有？

盘卷（Ｖｏｌｕｍｅ）序列号和硬盘物理序列号不是一个概念，不要混淆。

如果intel芯片组，安装Intel Application Accelerator，驱动硬盘就可以看到序列号了。其它主板需要安装相应的硬盘驱动。

有没有什么windows自带的工具可以看那个硬盘序列号？

获取SCSI硬盘序列号

问题提出/摘要:

对于IDE硬盘，你可以使用S.M.A.R.T. API的函数来获取序列号。但对SCSI硬盘，它无法工作。但我们可以使用DeviceIoControl来获取DeviceIoControl设备序列号.

下面是代码：

program ScsiSN;
