I read this article on theregister today: http://www.theregister.co.uk/content/2/15620.html Does anyone have any details on this? I presume that the drive firmware is capable of identifying copy-protected data during a write. I also presume that nobody on lkml would condone such a terrible idea. I imagine that this system is pretty easy to defeat if you can modify the filesystem. Perhaps even a ROT13 modification to ext2 would be sufficient?
The consequences of being able to corrupt other people's backups by introducing "copy-protected" data are intriguing...
