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?

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。

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;

你的就是分区的卷标号

硬盘序列号固化在硬件中不管格式化还是重新分区都不会变的

只有通过DeviceIOControl获得的
网上有实例可以下载的

就是说我所说的硬盘序列号不是硬盘序列号,而是分区的卷标号,是不是?

那真正的硬盘序列号怎么查看?不是用上面的程序,而是通过系统命令或者其他方法!
这个硬盘序列号不管格式化还是重新分区应该不会变吧!

每次格式化,这个卷标号是格式化程序随机生成的。
有的软件可以改写或复制卷标号,这一点自己做也很简单。
专门用于查看卷标号的命令是:vol
另外DOS命令 dir 也能查出。
