Yesterday my Home Assistant system failed to boot after doing upgrades. I have some not so recent backups on my NAS with which I restored my system. But I did a backup immdiately prior to the upgrade, but it must be on the non-booting SD card. I’ve tried mounting it via a USB SD card adapter on the restored system, and on a Debian machine, but am having trouble finding it in /dev. Any ideas on what to look for? And if I find the SD card device, what format is it for mounting? Or is the card hopelessly corrupted?
