I/O Errors

Jonathan Rentzsch:

I don’t have any statistics how common IO errors are versus total drive failures, but it’s clear that a single simple IO error could put most users into a jam they couldn’t get out of. As a user, I feel like there should be a high-level handling of this failure scenario. However, as a developer I’m unsure about the best course of action. Zero-filling was the right solution for this case, but certainly isn’t in many other cases, and it’s nontrivial for the software to make the decision for the user.
