Not a problem..I mean...not consecutive blocks...but want to write/read the whole file. not 1,2,3...something like...1,50,2000, etc....till 1 GB

Did you see my last post ?
You can use the func SeekTo_NthBlock to write to any block at any time.

// Writing randomly
short IsWritten[10485];
memset(IsWritten, 0, 10485*sizeof(short));
int TotalWritten = 0;
int WriteToBlock;

while (TotalWritten < 10485 )
{
      WriteToBlock = rand() % 10485;
      if ( IsWritten[WriteToBlock] )      continue;
      SeekTo_NthBlock(fp, WriteToBlock, 102400);
      fwrite(buff, 1, 102400, fp);
      IsWritten[WriteToBlock] = 1;
      ++TotalWritten;
}

Is it okay now ?

I guess you are able to read the post just above yours.
What does while(TotalWritten < 10485) mean ??
