关于ASP读取硬盘序列号的问题
下面两个代码都是网上找的，怎么读出来的号不一样呢？硬盘序列号是唯一的吗？到低哪个是正确的，我下了两款软件读出来的序列号都不一样。
<%@ LANGUAGE=VBScript%>
<%
Response.Buffer = True
Response.Expires = 0
Response.CacheControl = "Private"
Set fs = Server.CreateObject("Scripting.FileSystemObject")
Set drv = fs.GetDrive(Left(Server.MapPath("."), 2))
Response.Write "SerialNumber is " & drv.SerialNumber & "<br>"
Response.Write "TotalSize is " & drv.TotalSize & "<br>"
Set drv = Nothing
Set fs = Nothing
%>


<%
 Sub ShowDriveInfo(drvpath)
  Dim fs, d, s, t
  Set fs = CreateObject("Scripting.FileSystemObject")
  Set d = fs.GetDrive(fs.GetDriveName(fs.GetAbsolutePathName(drvpath)))
  Select Case d.DriveType
  Case 0: t = "未知"
  Case 1: t = "可移动"
  Case 2: t = "固定"
  Case 3: t = "网络"
  Case 4: t = "CD-ROM"
  Case 5: t = "RAM 磁盘"
  End Select
  s = "驱动器 " & d.DriveLetter & ": - " & t
  s = s & vbCrLf & "序列号： " & d.SerialNumber
  response.Write(s)
End Sub
call ShowDriveInfo("c:\")
%>

------解决方案--------------------
觉得这个读出来的是某个盘的序列号，比如D盘E盘的，而不是整个硬盘
