如何获得本机硬盘号(200分)

请问如何获得本机硬盘号,请大侠发正确的代码过来

>> function GetHDSerialNumber: LongInt;

> Description : Get the Serial Number of the Hard Disk where the Key File
lives.

> Input : none

> Output : Returns Serial Number of disk where is fKeyFileName
if success or -1 on error.
> Notes : This only returns SerialNumber under Win 95/NT, for
: win 3.1, I am using GetWinFlags which returns a LongInt
: that contains CPU and Mode information. Not as good, but
: far more reliable than trying to query the HD information
: from Win 3.1

==============================}
function GetHDSerialNumber: LongInt;
{$IFDEF WIN32}
var
pdw : pDWord;
mc, fl : dword;
{$ENDIF}
begin
{$IfDef WIN32}
New(pdw);
GetVolumeInformation(nil,nil,0,pdw,mc,fl,nil,0);
Result := pdw^;
dispose(pdw);
{$ELSE}
Result := GetWinFlags;
{$ENDIF}
end;

TO康凌,
要分也不可以这样要呀

查一下吧，好多这种帖子的。上面这个是取分区序列号的，不过一旦格式化分区，此号
就变了。现在给你一种取硬盘物理序号的（从DFW时找的）。不过在98下要做一个处理。
要把某个文件拷贝到某个目录中去，文件名好象是SMARTVSD.vxd,路径记不清了，在DFW
上搜一下或者在DFW离线资料库中搜一下就可以找到的。

truecat,你好这个在2000下怎么得不到硬盘号呢.请指正

Lbl_DriveType:Tlabel;
　　DriveType:WORD; //定义驱动器类型变量
　　DriveType:=GetDriveType(RootPathName); //获得RootPathName所对应的磁盘驱动器信息
　　case DriveType of
　　DRIVE_REMOVABLE:Lbl_DriveType.Caption:= '软盘驱动器';
　　DRIVE_FIXED : Lbl_DriveType.Caption:= '硬盘驱动器';
　　DRIVE_REMOTE: Lbl_DriveType.Caption:= '网络驱动器';
　　DRIVE_CDROM: Lbl_DriveType.Caption:= '光盘驱动器';
　　DRIVE_RAMDISK: Lbl_DriveType.Caption:= '内存虚拟盘';
　　end; //将该磁盘信息显示在Lbl_DriveType中
　　二、 用GlobalMemoryStatus函数获取内存使用信息
　　MemStatus: TMEMORYSTATUS; //定义内存结构变量
　　Lbl_Memory:Tlabel;
　　MemStatus.dwLength := size of(TMEMORYSTATU?
S);
　　GlobalMemoryStatus(MemStatus); //返回内存使用信息
　　 Lbl_Memory.Caption := format('共有内存: %d KB 可用内存: %dKB',[MemStatus.dwAvailPhys div 1024,MemStatus.dwTotalPhys div 1024]);
　　//将内存信息显示在Lbl_Memory中
　　三、 用GetSystemInfo函数获取CPU信息
　　SysInfo: TSYSTEMINFO;
　　Lbl_CPUName:Tlabel;
　　GetSystemInfo(SysInfo);//获得CPU信息
　　case SysInfo.dwProcessorType of
　　PROCESSOR_INTEL_386:Lbl_CPUName.Caption:=format('%d%s',[SysInfo.dwNumber Of Processors,'Intel80386']);
　　PROCESSOR_INTEL_486:Lbl_CPUName.Caption:=format('%d%s',[SysInfo.dwNumber Of Processors, 'Intel 80486']);
　　PROCESSOR_INTEL_PENTIUM:Lbl_CPUName.Caption:=format('%d%s',[SysInfo.dwNum
berOfProcessors, 'Intel Pentium']);
　　PROCESSOR_MIPS_R4000:Lbl_CPUName.Caption:=format('%d%s',[SysInfo.dwNumberOfProcessors, 'MIPS R4000']);
　　PROCESSOR_ALPHA_21064:Lbl_CPUName.Caption:=format('%d%s',[SysInfo.dwNumberOfProcessors, 'ALPHA 21064']);
　　end;//把CPU信息显示在Lbl_CPUName中。(

不会吧，不过我也见有有取不到的。
因为还是有一部分硬盘是没有序列号的，尤其是三星的硬盘。

能正常支持光驱(光盘)的检测。

注：如果返回值为'0000-0000'，则未检测到。

function GetHDSerialNumber(Drv : String): String;
var
VolumeSerialNumber : DWORD;
MaximumComponentLength : DWORD;
FileSystemFlags : DWORD;
begin
if Drv[Length(Drv)] =':' then Drv := Drv + '/';
GetVolumeInformation(pChar(Drv),
nil,
0,
@VolumeSerialNumber,
MaximumComponentLength,
FileSystemFlags,
nil,
0);
Result := IntToHex(HiWord(VolumeSerialNumber), 4) +
'-' +
IntToHex(LoWord(VolumeSerialNumber), 4);
end;

可以用下面单元文件中的函数试一下：

用TVicHW32吧，它可支持win9x,nt,2k,不仅是硬盘ID
用google搜一下，
如果找不到合适的，我可email you 5.0的破解版

谢谢,若有好的方法继续发给我.我定会补分给你
