Could you say why you need it (MBR)?

You can just open the raw disk device:

  CFile f,w;
  unsigned char buf[512];

  f.Open(L"\\\\.\\PHYSICALDRIVE0",0);
  f.Read(buf,512);
  f.Close();

You can just open the raw disk device:

That will only give you the data of track 0. It doesn't enable you to read the FAT/MBR if you don't know how to interpret the data of track 0.

Agreed, but the OP asked how to read it, not interpret it.

[OReubens]

the interpretation is just the same as when you would be able to read sectors explicitely as well. you would "need to know" how to interpret it then also.

opening the disk as a physical volums essentially puts all the sectors of the disk one after the other and you can access it linearly using the known file functions. It takes the cylinder/track/sector calculations out of the issue so it's a lot simpler at least. But interpretation still is the same.

For retrieve deleted folder and files.

Why not just use one of the many utilities out there that do that already?

Sir, you have no posting history here and you're asking questions that indicate you could be up to no good. You won't get that kind of help here, so you'll need to explain why you're asking what you're asking.

Sir so many expert here.I ask How to read MBR table for FAT and NTFS? I think in MBR have some kind of information,so i ask How to read MBR table for FAT and NTFS.
If i am wrong then please give me information how to get deleted folder and file.

And I asked why not just download one of the utilities that are available, which is a reasonable question, and you got snippy.

Personally, I have no idea, but if my goal was to retrieve deleted files, I'd let somebody else do the work and use what was out there.

What does MBR ( http://en.wikipedia.org/wiki/Master_boot_record ) have to do with File Allocation Table? with deleted folder and files?
