Oh, here's a fun thought: "(...) memory corruption can cause disk corruption. This is especially annoying because memory corruption can cause you to take a checksum of bad data and write a bad checksum." The amount of things that can go wrong in a computer scares me a little.

Seriously though: how do you guard against memory corruption? Hash as soon as you get data, check when you write, write hash to disk then read hash from disk and check hash against written data again? Is this... is this how we prevent things from breaking?
