Re: [Dev-C++] How to read/write directly a track/sector in a hard disk or CD

IMHO, there are many reasons for doing such, including security, data recovery, etc.  However, I've never seen this done in C/C++.  As you have to access low level IO functions, this is preferentially done is assembly, as I don't believe C/C++ have this capability.  At least, I've never found the need to research it.
 
I would recommend Googling for low level disk IO.  If you're really diligent, you can find out that there are undocumented features to disk controllers that significantly enhance data security.
