已知盘符,怎么取得它的硬盘号? (100分)

当有多块硬盘的时候,用盘符,怎么得到它的硬盘号?
我用DeviceIoControl的IOCTL_DISK_GET_DRIVE_LAYOUT参数取过
开始我以为是Signature的值,但是取出Signature后发现这个数很大(倒有点像系列号)
并且第一块硬盘和第二块硬盘之间的Signature值差距很大

谁有这方面的经验,来聊聊

试试这个行不行。
function tform1.Get_DiskSerialNo(DriveID : char) : string;
var
VolumeSerialNumber : DWORD;
MaximumComponentLength : DWORD;
FileSystemFlags : DWORD;
begin
result := '';
try
GetVolumeInformation(PChar(DriveID + ':/'),
nil, 0, @VolumeSerialNumber,
MaximumComponentLength, FileSystemFlags,
nil, 0);
result := IntToHex(HiWord(VolumeSerialNumber), 4) +
'-' + IntToHex(LoWord(VolumeSerialNumber), 4);
except

end;
end;

to 飘摇客:
谢谢你的回答,不过
我不是要系列号,我是要硬盘号
有两块盘,就会有0号和1号(在计算机管理的磁盘管理里边,你可以看到)

win2000能用就行

下面方法可以准确的得到硬盘的型号和生产序列号等参数！

如果硬盘有多个的话，修改里面的参数就可以查出第二、第三个硬盘的型号、ID等参数。


这是我程序中使用的。供参考！
procedure TForm1.BitBtn1Click(Sender: TObject);
var
S1, S2, S3: string;
W5: Word;
W4, W3: ULong;
begin
StaticText1.Caption = '薛自影设计 xueziying@cn99.com'
GetIdeDiskSerialNumber(S1, S2, S3, W3, W4, W5);
Label1.Caption := '序列号：' + S1;
Label2.Caption := '硬盘型号：' + S2;
Label3.Caption := '硬件版本：' + S3;
Label6.Caption := 'TotalAddressableSectors：' + inttostr(W3);
Label7.Caption := 'SectorCapacity：' + inttostr(W4);
Label8.Caption := 'SectorsPerTrack：' + inttostr(W5);

to Block_K_E:
你的这段代码很有用,我会给你一些分.但是这个还不是我要的答案.
可能我前面没说明白,再举个例子吧:
有两块硬盘(主盘,副盘,编号是0和1),在它们上面的逻辑分区分别是:
0: C: F: H:
1: D: E: G:
我现在拿到一个"E:",怎么知道它是在1号盘上面?
如果拿到的是"C:",怎么怎么它是在0号盘上面?
这就是我的问题

刚才看了你的代码,发现有一个参数: DFP_RECEIVE_DRIVE_DATA
在Delphi6的MS DSK帮助上找不到,可能是帮助太老了,全部没有DFP打头的参数
你能不能再帮我研究一下?
或者给点提示
thanks
