So you've had one more of these POR events.

ID # 235 Power Recovery Count
A count of the number of sudden power off cases. If there is a sudden
power off, the firmware must recover all of the
mapping and user data during the next power on. This is a count of the
number of times this has happened.

I wonder if there is a correlation with these POR events and
corruption? And I wonder what's causing the POR event? Is this machine
crashing/hanging and you're doing a force power off? Or is it suspend
to RAM or suspend to disk? And if you stop doing those things, does
the corruption still happen?
