WMI的硬盘序列号换位 [英] WMI HDD Serial Number Transposed
问题描述
我有一些代码来获取从WMI硬盘驱动器的序列号。
<预类=郎-CS prettyprint-覆盖>
SelectQuery selectQuery =新SelectQuery（Win32_PhysicalMedia）;
ManagementObjectSearcher搜索=
新ManagementObjectSearcher（selectQuery）;
的foreach（的ManagementObject wmi_PM在searcher.Get（））
{
字符串str = wmi_PM [的SerialNumber];
}
起初我还以为这是工作和获取正确的序列号。试图虽与比较使用它之后，我发现了WMI报告的数量是不完全正确的。该WMI序列号包着一堆以及字符被调换的空间。
印刷在贴纸并返回由一些工具（可能是实际的驱动器序列号使用的DeviceIoControl）为3RH8B1BG，WMI却返回&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP; R38H1BGB。
真正的连环＃：3RH8B1BG
WMI序列号：R38H1BGB
一些工具，如SiSoftware Sandra里虽然返回此衬垫和转数，它不是实际的序列号。该WMI值是序列号，如果你每转其他职务。这正常吗？我只是代码将其移至正确的价值？
我会尽量避免使用WMI，但它似乎怎么办在网上的东西，现在带回WMI例子任何搜索。
生产用于不同的2种不同的硬盘驱动器的WMI值的序列号都被调换所以它不是一个单一的磁盘。
更新：发现使用的DeviceIoControl
&NBSP一些代码; NBSP&; NBSP&; NBSP&; NBSP&;的 http://addressof.com/blog/archive/2004/02/14/392.aspx
令人惊讶地，DeviceIoControl的返回一个转置的序列号为好。
在由CorySmith上面的代码它有一个SwapChars功能
专用共享功能SwapChars（BYVAL字符（）为CHAR ）作为字符串
。对于我作为整数= 0〜chars.Length - 2步骤2
chars.Reverse（字符，1,2）
下一步
返回新建字符串（字符） .Trim

C ++的，他提到代码具有翻转为：
<预类=郎-C prettyprint-覆盖>
//功能IDE硬盘
的序列号//使用IOCTL_STORAGE_QUERY_PROPERTY命令解码
的char * flipAndCodeBytes（为const char * str中，
INT POS，
INT翻转，
的char * BUF）
{
...
}
想这是对的DeviceIoControl和WMI，斜面标准相信任何其他的解决方案或例子我跑的横跨没有这个。
找到工作解决方案进行解码的真正高清连续剧。下面的链接包含的代码，即使没有管理员权利解码：的解码源
但如果你从上面Vista中的Win32_PhysicalMedia WMI类获得连续出版物可能不会在所有情况下工作。然后，你必须使用Win32_DiskDrive类（根据此链接： 10月27日周二计量戈的回答2009年上午03时12
我添加的代码（在VB，因为我通常是在VB.NET代码）。我不想去偷别人的代码。我包括尽可能多的相关信息，仍然有些链接到在代码中原来的编码器，现在还包括可移动驱动器解码Serialnumbers（在相同的例程）。
希望它帮助。

I have some code to fetch a hard drive serial number from the WMI.
SelectQuery selectQuery = new SelectQuery("Win32_PhysicalMedia");
ManagementObjectSearcher searcher =
new ManagementObjectSearcher(selectQuery);
foreach (ManagementObject wmi_PM in searcher.Get())
{
string str = wmi_PM["SerialNumber"];
}
At first I thought it was working and retrieved the correct serial number. After trying to use it with a comparison though, I found out the number the WMI reports is not exactly correct. The WMI serial number is padded with a bunch of spaces as well as the characters are transposed.
The actual drive serial number printed on the sticker and returned by some tools (probably using DeviceIoControl) is "3RH8B1BG", WMI however returns " R38H1BGB".
Real Serial#: 3RH8B1BG
WMI Serial#: R38H1BGB
Some tools like SiSoftware Sandra, return this padded and transposed number, its not actual serial number though. The WMI value is the serial number if you transpose every other position. Is this normal? should I just code to transpose it to the correct value?
I try to avoid using the WMI but it seems any search for how to do something on the net now bring back WMI examples.
The WMI value serial number for 2 different hard drive of different manufactures are both transposed so its not a single disk.
Update: found some code using DeviceIoControl
http://addressof.com/blog/archive/2004/02/14/392.aspx
Surprisingly, DeviceIoControl returns a transposed serial number as well.
In the code by CorySmith above it has a SwapChars function
Private Shared Function SwapChars(ByVal chars() As Char) As String
For i As Integer = 0 To chars.Length - 2 Step 2
chars.Reverse(chars, i, 2)
Next
Return New String(chars).Trim
End Function
The c++ code he mentions has the flip to:
// function to decode the serial numbers of IDE hard drives
// using the IOCTL_STORAGE_QUERY_PROPERTY command
char * flipAndCodeBytes (const char * str,
int pos,
int flip,
char * buf)
{
...
}
guess that's standard for DeviceIoControl and WMI, cant believe any of the other solutions or examples i ran across did not have this.
Found a working Solution to decode the real HD-Serials. The following Link contains the code to decode even without admin-rights: Decoding Source
But if you get the Serials from the Win32_PhysicalMedia WMI class above Vista it may not work in all cases. Then you have to use the Win32_DiskDrive class (according to this Link: Jiliang Ge's Answer from Tuesday, October 27, 2009 3:12 AM
I added the code (in VB, since I usually code in VB.NET). I didn't want to steal someone else's Code. I included as much Infos and still some links to the Original Coder within the code. It now also includes decoding Serialnumbers from Removable Drives (in the same routine).
Hope it helps.
