So I've been sitting here trying to figure out how to respond to this (and one
or two other messages).  I think there must be some sort of miscommunication
happening because I can't otherwise explain why you're asking what you are.
The options seem to be:

1. You're unaware of how vulnerable to faults ECC is.
2. You're unaware that computers experience faults.
3. We're talking at cross purposes/miscommunicating in some way.

Before I type up a long essay on #1 or #2 (which I'm not terribly keen on
doing) I want to make sure that you're really asking what you appear to be
asking, and one or both of us hasn't misinterpreted the others' position.

Peter.
