在Delphi7中，如何检索硬盘唯一的序列号？

标签： delphi hardware delphi-7

您好 我想检索HDD唯一（硬件）序列号。 我使用了一些功能，但在Windows 7或Vista中，由于管理员权限，它们无法正常工作。 是否可以在不以管理员身份运行的情况下检索它？

根据发布的问题评论Sertac中的链接，我发现了这个interesting C++ question，其中Fredou回复了codeproject example showing how to do this in .NET的一个很好的链接，而link to Borland C++ code又是基于article和this C++ code。

很酷的是，http://www.delphipraxis.net/564756-post28.html也可以作为非管理员用户使用！

现在你需要有人帮助你将这个C ++代码翻译成Delphi。

编辑：找到一个为您完成此任务的Delphi单元。

我为它写了一些示例用法：

program DiskDriveSerialConsoleProject;

{$APPTYPE CONSOLE}

uses
  Windows,
  SysUtils,
  hddinfo in 'hddinfo.pas';

const
  // Max number of drives assuming primary/secondary, master/slave topology
  MAX_IDE_DRIVES = 16;

procedure ReadPhysicalDriveInNTWithZeroRights ();
var
  DriveNumber: Byte;
  HDDInfo: THDDInfo;
begin
  HDDInfo := THDDInfo.Create();
  try
    for DriveNumber := 0 to MAX_IDE_DRIVES - 1 do
    try
      HDDInfo.DriveNumber := DriveNumber;
      if HDDInfo.IsInfoAvailable then
      begin
        Writeln('VendorId: ', HDDInfo.VendorId);
        Writeln('ProductId: ', HDDInfo.ProductId);
        Writeln('ProductRevision: ', HDDInfo.ProductRevision);
        Writeln('SerialNumber: ', HDDInfo.SerialNumber);
        Writeln('SerialNumberInt: ', HDDInfo.SerialNumberInt);
        Writeln('SerialNumberText: ', HDDInfo.SerialNumberText);
      end;
    except
      on E: Exception do
        Writeln(Format('DriveNumber %d, %s: %s', [DriveNumber, E.ClassName, E.Message]));
    end;
  finally
    HDDInfo.Free;
  end;
end;

begin
  ReadPhysicalDriveInNTWithZeroRights;
  Write('Press <Enter>');
  Readln;
end.

编辑： RAID配置需要特殊规定。

例如，我有一个带有多个RAID 5阵列的RAID系统;只显示第一个，并且它不显示驱动器序列号，而是显示RAID阵列的序列号：

VendorId: AMCC
ProductId: 9550SXU-16ML
ProductRevision: 3.08
SerialNumber: 006508296D6A2A00DE82
SerialNumberInt: 688416000

答案 1 :(得分：6)

您可以使用WMI (Windows Management Instrumentation)获取与Windows硬件相关的信息。

存在两个wmi类，它们公开了一个名为SerialNumber的属性，它存储the Number allocated by the manufacturer to identify the physical media.这些类Win32_DiskDrive和Win32_PhysicalMedia。来访问这些类的SerialNumber属性您必须知道磁盘的DeviceId类，这类是\\.\PHYSICALDRIVE0。另一种方法是使用将物理驱动器与逻辑驱动器（C，D，E）链接的关联类

因此您必须先找到此链接以获取序列号。找到这种关联的顺序是这样的。

Win32_DiskPartition - ＆gt; Win32_LogicalDiskToPartition - ＆gt; Win32_DiskDrive

注意1 ：Windows {@ 1}}类的SerialNumber属性在Windows Server 2003，Windows XP，Windows 2000和Windows NT 4.0中不存在，所以你如何正在谈论使用Windows Vista或Windows 7，可以正常使用。

注意2 ：代码不需要管理员帐户运行。
