Forum ever reply help me.
Could you say why you need it (MBR)?
You can just open the raw disk device:
Code:CFile f,w;
unsigned char buf[512];
f.Open(L"\\\\.\\PHYSICALDRIVE0",0);
f.Read(buf,512);
f.Close();
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.Quote:

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.Quote:

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

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

Sorry, there's no intention to offend or urge you to something like snarling at me back, but if I heard somebody asks questions of the kind in public forums (what gives me out a completely unprofessional approach) and then releases another "file recovery!!!" product in a half a year, I would do all my best to avoid the one.
No it's my project.Quote:

Is it possible to read MBR in VC++? Or i can try some other language.Please advice me
Question to all: Is there really no way to open a sector image of the volume instead of the physical disk? This would entirely bypass the MBR and I really can't believe that it isn't possible in current Win incarnations (at least if you have sufficient rights to access the MBR anyway).Quote:

You think wrong. MBR stands for Master Boot Record. It has nothing to do with files and folders, but describes disk partitions instead.Quote:
