Why can't I write a program that tries to expand itself to use any available space, then runs in to a wall if the "empty space" is actually encrypted data? If the space used by data + my program adds up to less than the total capacity of the disk, it indicates something is hiding right?
- ehsanu1 15y agoYou seem to be misunderstanding. Read your parent's last line again. "Empty space" is indistinguishable from encrypted data. On the hard disk, everything will just look like randomized bits, empty space and data alike. There is no way to write the program you propose without the encryption key(s). So there's no way to tell, unless you have all the keys.
- tomflack 15y agopraptak's reply above yours explained exactly what I needed explained. The encrypted data will just be written over.
- praptak 15y agoThe program will just overwrite the data of the hidden volume. That's why it's important to have a lot of empty ("empty") space on the primary volume when you have a hidden volume there.
