Is that a fair analogy?
Either way, thanks for the helpful suggestions. I now know what to look out for.
One thing you know about both... the cause was a hardware failure. The other thing you know is that hardware is not self-healing (well, outside of Borg hardware, that is...).
You don't know (in your situation) specifically what hardware failed, but the usual suspects are either the hard drive or the memory card. And, it is my experience with hard drives, that random file corruption is nearly always an early warning for a more catastrophic drive failure. I'm not so sure about a flash card failure modes.
Of course, it could have been a bad connection or it could have been some other failure, but flash cards are inexpensive enough that I just would not trust it anymore and I would replace it.
It is unlikely to have been a random alignment of the stars or some other semi-mysterious event. It was a real failure with a real cause.
You have some protection since you use a dual card setup, but if one of your cards has exhibited failure in the past, it seems to me you have increased the chances of suffering a double failure. How risk averse you are is only for you to decide.
