Apple

Hi,

I have studied this article of HFS Plus file system at http://dubeiko.com/development/FileSystems/HFSPLUS/tn1150.html and wants to implement this in Mac and for this I need to access disk drives at raw level so that I can read all parameters given in this article that’s why em asking for any help that could lead me to this…

In windows I can do this using c but how its works in Mac no idea so need help….

#include "stdafx.h"

#include <stdio.h>

#include <stdlib.h>

#include <windows.h>

#include <tchar.h>

#include <iostream>

#include <winioctl.h>

using namespace std;

unsigned long diskread(unsigned char Buffer[])

{

int _nsect=1;

unsigned long dwRet = 0;

HANDLE hDev=CreateFile(L"\\\\.\\PHYSICALDRIVE0",GENERIC_READ,FILE_SHARE_WRITE,0,OPEN_EXISTING,0,0);

SetFilePointer(hDev,_nsect*512,0,FILE_BEGIN);

ReadFile(hDev,Buffer,1024,&dwRet,0);

//ReadFile

CloseHandle(hDev);

return dwRet;

}

unsigned long diskwrite(unsigned char Buffer[])

{

unsigned long dwRet = 0;

HANDLE hDev=CreateFile(L"\\\\.\\PHYSICALDRIVE0",GENERIC_WRITE,FILE_SHARE_WRITE,0,OPEN_EXISTING,0,0);

WriteFile(hDev,Buffer,512,&dwRet,0);

CloseHandle(hDev);

return dwRet;

}

//int _tmain(int argc, _TCHAR* argv[])

void main(void)

{

unsigned char Buffer[1024]={0};

unsigned long dwRet = 0;

dwRet = diskread(Buffer);

int a=0;

// std::cin>>a;

//scanf("%d",a);

printf("dwRet = %ld", dwRet);

for(int i = 0; i < 1024; i++)

{

if(i == 0)

printf("\n\t");

printf(" ");

printf("X", Buffer[i]);

}

printf("\n");

//cin>>a;

//diskwrite(Buffer);

//return 0;

}
