Persistent Data

I needed someone to write me a DLL in C, C++, VB or any language of his or her choice. The DLL should be able to write and retrieve information from certain sectors of the hard disk. Therefore, it will not be accessible by windows and won't be recognized as a file. Those sectors will be encrypted and can only be understood and accessed by the DLL. Of course, I understand if the user formats his hard disk, the sectors will be lost. Coders who are able to avoid that get a honest bonus. My idea is to keep the data even after a format, is to somehow mark the sector as bad but yet keep information in it. I don't know if this is possible and only an experienced C or C++ developer could tell me. So, basically, my software will be treating the DLL as a DLL for normal file access whereas it would be much complicated and would encrypt and store the information on raw sectors of the hard disk. Let me repeat what I want it to achieve doing this is: 1)Non accessible by Windows or any Windows Software 2)Non readable by any software (especially on other Operating Systems or in DOS) with help of encryption 3) Remains on disk as long as the Disk isn't formatted (unless u fool this too). There shouldn't be any problem if the disk is defragmented. I would like to close a deal with a buyer asap. If you are interested... we can discuss further.
