I’ve actually been getting this error on and off for months without having swapped out my SSD at all. It only happens after my FW16 has been in Hibernation for a little while. No idea on timing because it’s always overnight. I wake up to that error and the fans kicked on at full tilt and a lot of heat coming from the bottom for some reason. Have yet to figure it out. Also running W11 on a 4TB 2280 SSD. I have a ticket to support on thermal issues referenced in this thread so hopefully I’ll get a new mainboard that will solve both issues, but I hope there’s a better solution.
