What's with this highlighted comment? Are you guaranteed corruption on every half terabyte?

Based on my reading of the article, it says that OpenBSD always uses the same key, scr_key[0], and does not implement the use of different keys for different parts of the disk. I haven't looked at the OpenBSD source code to confirm this, though.
