GetVolumeInformation

[Happyledian]

aningstar,你在Delphi 5中调试过没有,我听说该程序在Win2000中也不行.不知能不能帮忙
测试一下!谢了.

GetVolumeInformation是得到硬盘逻辑分区号,不是我想要的.谁能看看.

one:

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

在Win2000中能不能实现?

用deviceioctrl，具体看msdn
