Actually, you could fool a lot of people by creating a hidden disk partition. Nobody would know there was anything hidden unless they did ... this is very easy in unix: put your secret stuff in a directory, then mount a file system on that directory.
Another nice way is to remove the dev files for the disk at shutdown time. Then at reboot, you'd have to manually create dev files (knowing the major and minor numbers) and manually mount the file system. There'd be no trace. This would work real well with big disks... Is that a 1.0, 1.1 or 1.2G filesystem? How much swap is allocated, anyway? You could also use a litte steganography and spare out a set of ``bad'' sectors. Some controllers will do the sector sparing for you (transparently to the OS)... All sorts of opportunities ;-) Eric Blossom
