解决方法
我讨厌组件所以这里是一些代码
var
RawMBR : array [0..511] of byte;
btsIO : DWORD;
begin
hDevice := CreateFile('\\.\PHYSICALDRIVE1',GENERIC_READ,FILE_SHARE_READ or FILE_SHARE_WRITE,nil,OPEN_EXISTING,0);
if hDevice <> INVALID_HANDLE_VALUE then
begin
SetFilePointer(hDevice,512 * 0,FILE_BEGIN); // replace 0 with sector that you wish to read
ReadFile(hDevice,RawMBR[0],512,btsIO,nil);
CloseHandle(hDevice);
end;
end;
