Ok, I’m still not clear on exactly what you’re trying to achieve as I can’t quite see the connection between somehow preventing certain files being duplicated when cloning the disk and preventing yourself from reinstalling the system.
Premises:
Very important files on disk (somehow) protected from copy/mv/clone whatever.
Reinstalling my OS wipes the disk.
Therefore, I would lose those very important files if I were to attempt a wipe. If said files are important enough for me to reconsider wiping, then the act of protecting them from copy/mv/clone has fulfilled its job of preventing me from reinstalling the OS.
Bear in mind that reinstalling the system would replace all of the OS, so there’s no way to leave counter-measures there, and the disk itself can’t do anything to your data, even if it could detect a clone operation.
I understand.
If what you’re trying to protect against is someone who knows everything you do accessing your data, you could look to use TPM to store the encryption key for your FDE. That way you don’t know the password, it’s stored encrypted with a secret key that is, in turn, stored and protected by your CPU. That way a disk clone couldn’t be used on any hardware except your specific machine.
Very interesting. A couple of questions:
Is it possible to only protect a set of files through this? So not the entire disk?
