我编写了三种不同的方法,它们使用本机CreateFile
和DeviceIoControl
调用来检索 HDD 序列号(而不是型号)。第一个用S.M.A.R.T.
,第二个用Storage Query
,第三个用SCSI PassThrough
。我的大部分代码都是基于这个线程的内容(有一些修复和改进)。
以下是我使用diskid32 实用程序得到的结果:
Trying to read the drive IDs using physical access with admin rights
Drive Model Number________________: [ST975XXXXX]
Drive Serial Number_______________: [ 6WS2XXXX]
Trying to read the drive IDs using physical access with zero rights
Product Id = [ST975XXXXX]
Serial Number = [6WS2XXXX]
Trying to read the drive IDs using Smart
Drive Model Number________________: [ST975XXXXX]
Drive Serial Number_______________: [ 6WS2XXXX]
现在,这里是使用我的方法的结果:
S.M.A.R.T. = 6WS2XXXX
Storage Query = 6WS2XXXX
SCSI PassThrough = ST975XXXXX
嗯...休斯顿我们这里有问题。使用前两种方法,我得到了正确的序列号。最后一个我得到了非常糟糕的型号。现在,这是我的代码:
--- METHOD ---
internal static String GetHardDiskSerialSCSIPassthrough(SafeFileHandle deviceHandle)
{
IntPtr bufferPointer = IntPtr.Zero;
String serial = String.Empty;
UInt32 bytesReturned;
SCSIPassthroughBuffered bspt = new SCSIPassthroughBuffered();
bspt.SPT.Length = (UInt16)Marshal.SizeOf(bspt.SPT);
bspt.SPT.CommandDescriptorBlockLength = 16;
bspt.SPT.DataIn = 0x1;
bspt.SPT.DataTransferLength = 64;
bspt.SPT.DataBufferOffset = new IntPtr(Marshal.SizeOf(bspt) - 64);
bspt.SPT.TimeOutValue = 60;
bspt.SPT.CommandDescriptorBlock = new Byte[] { 0x12, 0x1, 0x80, 0x0, 64, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0 };
Int32 bufferSize = Marshal.SizeOf(bspt);
try
{
bufferPointer = Marshal.AllocHGlobal(bufferSize);
Marshal.StructureToPtr(bspt, bufferPointer, true);
if (DeviceIoControl(deviceHandle, 0x4D004, bufferPointer, (UInt32)bufferSize, bufferPointer, (UInt32)bufferSize, out bytesReturned, IntPtr.Zero) && (bytesReturned > 0))
{
SCSIPassthroughBuffered result = (SCSIPassthroughBuffered)Marshal.PtrToStructure(bufferPointer, typeof(SCSIPassthroughBuffered));
serial = Encoding.ASCII.GetString(result.Buffer, 0, result.Buffer.Length).Replace("\0", String.Empty).Trim();
}
}
finally
{
Marshal.FreeHGlobal(bufferPointer);
}
return serial;
}

我究竟做错了什么?也许使用了错误的 CDB?
