获取SCSI硬盘序列号
问题提出/摘要:
对于IDE硬盘,你可以使用S.M.A.R.T. API的函数来获取序列号。但对SCSI硬盘,它无法工作。但我们可以使用DeviceIoControl来获取DeviceIoControl设备序列号.
回答:
下面是代码:
program ScsiSN;
// 目的:简单的控制台程序来显示SCSI硬盘的序列号
{$APPTYPE CONSOLE}
uses
Windows, SysUtils;
//-------------------------------------------------------------
function GetDeviceHandle( sDeviceName : String ) : THandle;
begin
Result := CreateFile( PChar('//./'+sDeviceName),
GENERIC_READ or GENERIC_WRITE,
FILE_SHARE_READ or FILE_SHARE_WRITE,
nil, OPEN_EXISTING, 0, 0 )
end;

通过它你可以获取型号名称, firmware revision,序列号以及其它有关IDE硬盘的信息.
回答:
相关构件:
IdeInfo.zip
许多FAQ中推荐使用GetVolumeInformation来获取硬盘序列号。但是那获取的是卷的序列号,而不是硬盘的序列号。卷的序列号是在分区格式化时生成或修改。一些公司使用复制工具来为全部新计算机安装软件----通过将一个硬盘复制到其它硬盘,当然,所有这些计算机上卷的信息(包括序列号)都是相同的。
我建议另外的一个方法:获取真正硬盘的序列号。
不幸的是,下列代码只能工作在IDE硬盘上。
