当硬盘在 IDE Primary master 时,该函数不用作任何改动就能正常运行(98、2K、XP下通过)取得硬盘序列号(98下要将system下的smartvsd.vxd先复制到Windows/system下的IOSUBSYS目录下,重新启动后才可以使用)但当硬盘在其它端口时 IDE Primary slave(IDE Secondary master/slave),函数不能取得硬盘序列号后来研究了一下,发现有两个地方是硬盘接口的参数:
1.
hDevice := CreateFile( '\\.\Scsi0:',
GENERIC_READ or GENERIC_WRITE,
FILE_SHARE_READ or FILE_SHARE_WRITE,
nil, OPEN_EXISTING, 0, 0 );
//win2000中,当硬盘在 IDE Primary master/slave 时应为Scsi0
//当硬盘在 IDE Secondary master/slave 时应为Scsi1
2.
bDriveNumber
//win2000中,当硬盘在 IDE Primary master/slave 时应为 0
//当硬盘在 IDE Secondary master/slave 时应为 1上面在win2000里测试通过,但在98下不知道该如何更改参数(适应上面说的四种情况)?有实际做过的能不能给予提示,非常感谢!!!
早就放弃它了可能是PhysicalDriver0这样吧现在都以2000为基本平台了
以前有好多。。
有个叫三尺不立之弓的朋友写过个 demo 你找找
我可以放弃Win98,但不能放弃使用Win98的用户呀
PhysicalDriver0这样是不行的,我在Win2000里试了,是Scsi0/Scsi1,对应master/slave,但98里不知道这样设置boytomato(深爱一人叫颖的女孩!):那些函数与此函数都差不多呀98里怎么设置CreateFile函数的文件名?
{$IFDEF WIN32}
var
pdw : pDWord;
mc, fl : dword;
{$ENDIF}
begin
{$IfDef WIN32}
New(pdw);
GetVolumeInformation(Pchar('c:\'),nil,0,pdw,mc,fl,nil,0);
Result := pdw^;
dispose(pdw);
{$ELSE}
Result := GetWinFlags;
{$ENDIF}
end;

ntemp1:=GetHDserialNumber;
IDE Primary master时, 文件名为Scsi0,bDriveNumber为0
IDE Primary slave 时, 文件名为Scsi0,bDriveNumber为1
IDE Secondary master时,文件名为Scsi1,bDriveNumber为0
IDE Secondary slave 时,文件名为Scsi1,bDriveNumber为1win98中,
IDE Primary master时,文件名为SMARTVSD,bDriveNumber为0测试通过
但其它三种情况下,文件名为SMARTVSD,bDriveNumber为0时不能通过,不知道参数怎么设置PhysicalDrive0是不行的,2000里都不行!
我公司的项目都放弃Win98用户了:)
还有,如果cmos中设置不用S.M.A.R.T控制硬盘,则smartvsd就不能管理该硬盘。
1.取硬盘序列号:有的硬盘没有序列号(如三星),且没有在各种操作系统(98/2K/XP)下的通用的获取方法
2.CPU序列号:有的CPU就没有序号
3.主板序列号:有的主板也没有序号
4.网卡序列号:很多机器不装网卡,也不行哎,不知道计算机里那个部件的序列号是唯一的,并且有通用的获取方法?(用于软件注册)
