Win32_DiskDrive 签名属性

发布于 2024-08-03 00:39:42 字数 88 浏览 3 评论 0原文

有谁知道 Win32_DiskDrive WMI 类的 Signature 属性是什么？它是唯一的还是用户可以像磁盘卷序列号一样更改它？

谢谢。

“签名”属性是随 Windows XP 引入的，用于用作共享群集磁盘的磁盘。根据我的理解，它是在磁盘第一次连接到 Windows 系统时创建的，即使磁盘通过另一个控制器连接（或者在集群场景中，甚至通过另一台计算机）也不会更改。

详细解释参见MSDN：

我可以通过提供有关“Win32_DiskDrive WMI 类”的一些重要详细信息来帮助您。

将以下代码复制到您的 C# 项目。

    public static string HardDiskID()
    {
        ManagementClass partionsClass = new ManagementClass("Win32_DiskDrive");
        ManagementObjectCollection partions = partionsClass.GetInstances();

        string hdd = string.Empty;

        foreach (ManagementObject partion in partions)
        {
            hdd = Convert.ToString(partion["SerialNumber"]);

            if (hdd != string.Empty)
                return hdd;
        }

        return hdd;
    }

注意 - 上面代码的“SerialNumber”字符串可以替换为以下任何硬盘属性。

  uint16   Availability;
  uint32   BytesPerSector;
  uint16   Capabilities[];
  string   CapabilityDescriptions[];
  string   Caption;
  string   CompressionMethod;
  uint32   ConfigManagerErrorCode;
  boolean  ConfigManagerUserConfig;
  string   CreationClassName;
  uint64   DefaultBlockSize;
  string   Description;
  string   DeviceID;
  boolean  ErrorCleared;
  string   ErrorDescription;
  string   ErrorMethodology;
  string   FirmwareRevision;
  uint32   Index;
  datetime InstallDate;
  string   InterfaceType;
  uint32   LastErrorCode;
  string   Manufacturer;
  uint64   MaxBlockSize;
  uint64   MaxMediaSize;
  boolean  MediaLoaded;
  string   MediaType;
  uint64   MinBlockSize;
  string   Model;
  string   Name;
  boolean  NeedsCleaning;
  uint32   NumberOfMediaSupported;
  uint32   Partitions;
  string   PNPDeviceID;
  uint16   PowerManagementCapabilities[];
  boolean  PowerManagementSupported;
  uint32   SCSIBus;
  uint16   SCSILogicalUnit;
  uint16   SCSIPort;
  uint16   SCSITargetId;
  uint32   SectorsPerTrack;
  string   SerialNumber;
  uint32   Signature;
  uint64   Size;
  string   Status;
  uint16   StatusInfo;
  string   SystemCreationClassName;
  string   SystemName;
  uint64   TotalCylinders;
  uint32   TotalHeads;
  uint64   TotalSectors;
  uint64   TotalTracks;
  uint32   TracksPerCylinder

i can help you with by giving some important details about "Win32_DiskDrive WMI class".

copy following code to your c# project.

    public static string HardDiskID()
    {
        ManagementClass partionsClass = new ManagementClass("Win32_DiskDrive");
        ManagementObjectCollection partions = partionsClass.GetInstances();

        string hdd = string.Empty;

        foreach (ManagementObject partion in partions)
        {
            hdd = Convert.ToString(partion["SerialNumber"]);

            if (hdd != string.Empty)
                return hdd;
        }

        return hdd;
    }

Note--above code's "SerialNumber" string can replace with following any hard disk attributes.

  uint16   Availability;
  uint32   BytesPerSector;
  uint16   Capabilities[];
  string   CapabilityDescriptions[];
  string   Caption;
  string   CompressionMethod;
  uint32   ConfigManagerErrorCode;
  boolean  ConfigManagerUserConfig;
  string   CreationClassName;
  uint64   DefaultBlockSize;
  string   Description;
  string   DeviceID;
  boolean  ErrorCleared;
  string   ErrorDescription;
  string   ErrorMethodology;
  string   FirmwareRevision;
  uint32   Index;
  datetime InstallDate;
  string   InterfaceType;
  uint32   LastErrorCode;
  string   Manufacturer;
  uint64   MaxBlockSize;
  uint64   MaxMediaSize;
  boolean  MediaLoaded;
  string   MediaType;
  uint64   MinBlockSize;
  string   Model;
  string   Name;
  boolean  NeedsCleaning;
  uint32   NumberOfMediaSupported;
  uint32   Partitions;
  string   PNPDeviceID;
  uint16   PowerManagementCapabilities[];
  boolean  PowerManagementSupported;
  uint32   SCSIBus;
  uint16   SCSILogicalUnit;
  uint16   SCSIPort;
  uint16   SCSITargetId;
  uint32   SectorsPerTrack;
  string   SerialNumber;
  uint32   Signature;
  uint64   Size;
  string   Status;
  uint16   StatusInfo;
  string   SystemCreationClassName;
  string   SystemName;
  uint64   TotalCylinders;
  uint32   TotalHeads;
  uint64   TotalSectors;
  uint64   TotalTracks;
  uint32   TracksPerCylinder
