What do you mean by disk?
Hmm, some kind of copy protection?
This is not a simple task, which can be shortly answered on a discussion board.
I assume this is a try to hide some kind of passwort (?).
Low-level disk access would do it (e.g. writing the encrypted password or checksum to an unused sector on the disk), but this needs some advanced hardware and assembly knowledge.

Really hard task, not a "low hanging fruit" for a newbie, isn't it?Quote:

Besides, this software protection technique is not so reliable: many tools allow a sector-to-sector copy of a given drive
(e.g. Norton's DiskImage).
There are many other ways to do this :
- check for Disk Serial Number AND implement some password checking
- if you are selling your software on diskettes, mark some sectors as bad, and check for these upon each startup
etc.
Combining these methods will increase the protection.
A more advanced technique is hardware copy protection - a device placed on the serial or parallel port, which returns some predefined values when querying it's ports.
You'd perform a quick search on the net (e.g. on www.google.com with keywords like Software AND copy AND protection AND source), maybe you're lucky and find some ready to use component and/or source code.
Bye!
