如何得到硬盘序列号[C#]
如何得到硬盘序列号[C#]

硬盘序列号（Serial Number）不等于卷标号（Volume Name），后者虽然很容易得到，但是格式化分区后就会重写，不可靠。遗憾的是很多朋友往往分不清这一点。
要得到硬盘的物理序列号，可以通过WMI，也就是Win32_PhysicalMedia.SerialNumber。可惜的是Windows 98/ME的WMI并不支持这个类，访问时会出现异常。
受陆麟的例子的启发，我们还可以通过S.M.A.R.T.接口，直接从RING3调用API DeviceIoControl()来获取硬盘信息，而不需要写VXD或者DRIVER。这样这个问题就解决了，我对它进行了封装，大量使用了P/Invoke技术，一个完整的Library。支持Windows 98-2003。
使用上很简单：
HardDiskInfo hdd = AtapiDevice.GetHddInfo(0); // 第一个硬盘
Console.WriteLine("Module Number: {0}", hdd.ModuleNumber);
Console.WriteLine("Serial Number: {0}", hdd.SerialNumber);
Console.WriteLine("Firmware: {0}", hdd.Firmware);
Console.WriteLine("Capacity: {0} M", hdd.Capacity);
下面是全部代码：
using System;
using System.Runtime.InteropServices;
using System.Text;
namespace Sunmast.Hardware
{
[Serializable]
public struct HardDiskInfo
{
///
/// 型号
///
public string ModuleNumber;
///
/// 固件版本
///
public string Firmware;
///
/// 序列号
///
public string SerialNumber;
///
/// 容量，以M为单位
///
public uint Capacity;
}

不要在装有SCSI硬盘的机器上尝试了，因为SCSI硬盘根本不存在序列号。
