SD card is dead?

Hello! Around a year I am on this RP 3B+ and samsung evo (64) and APC for stable electricity. Today morning no automations were working and UI is not loading.
Actually - I had issues with electricity last month and APC got off 5-6 times, but I fixed it and for a week everything is fine with electricity.
I reloaded pi and that did not help, I changed pi and that did not help.
How can I 100% check that it is SD card issue?
Finally looking for cheap nuc.

This thread may help you, it covers how to recover any snapshot, and that process will tell you if the SD itself has failed.

You can also connect a monitor and keyboard before starting it up, to see what’s going on.

This is by the way what I see on monitor going over and over again :slight_smile:

Actually, I do not need to recover it, I will start from scratch on nuc. Just wanted to be sure that it is sd card issue, not software.

From that image, I’m pretty sure it’ll turn out to be a dead/corrupt SD

If you don’t need the data on the SD card, format it in run f3write then f3read on the card to check if the card is OK.
