Hi
when I was programming under DOS and FAT16 I was using this code to read
sectors and store them into a file for future needs, now my partition are
FAT32 and I stuck in Microsoft Windows , Although I am using both 98 and XP
but I have problem in both.
My problem is I cant use absread() and abswrite() anymore, I dont know any
function for my aim,...
If anyone can help me to change this source code to a code that BCB5 could
compile and I can use it for FAT32, please tell me , thanks a milion :-)

#include "stdio.h"
#include "stdlib.h"
#include "conio.h"
#include "dos.h"

#define SECTORS_PER_READ 16
#define END_SECTOR  1000
void main(void){
  int i, strt, ch_out, start_sector=0;
  char buf[512*SECTORS_PER_READ];
  if (absread(2, SECTORS_PER_READ, start_sector, &buf) != 0){
   perror("Read ABS from Disk Problem! Program Exit !");
   exit(1);
  }
  printf("Reading OK and going on...\n");
  for (i=0; i<END_SECTOR; i++){
    //do something like store in a file
  }
}

Look at the documentation on the function CreateFile.  Look for
where it speaks of Physical Disks and Volumes.

Also look at the DeviceIoControl function and the IOCTL_* messages,
including IOCTL_DISK_GET_DRIVE_GEOMETRY_EX to get information which
will help in understanding where on the disk to look.

You can get that information from the platform SDK or from the
MSDN site:
