So I bought a Samsung EVO Plus 500GB SSD 5 months back and I have noticed that after each shutdown the unsafe shutdowns counter increases with one. I’ve had maybe 5 times I had to forcefully reboot the system that I know of.
I usually shutdown using the GUI or with the systemctl poweroff command, no issues there. The counter also increases when I boot and shutdown my other Linux system which is installed on my secondary SSD.
What might be causing this?
By the way the Samsung SSD is installed using a PCIe x4 card adapter.
