My Raspberry Pi, on which I host a Minecraft server, suddenly froze. I cannot not SSH in, nor can I join the Minecraft server. I ran the Minecraft server in Docker, via itzg/docker-minecraft-server. I turned off the Raspberry Pi, took out its microsd and plugged it into my PC, to at least attempt to run the Minecraft server from my PC to see if I still have the data. I tried to copy it with cp, but I got an input-output error. Could this be the filesystem’s fault? And how can I fix this? If you need any additional info about this crash, please do not hesitate to ask.
I believe your SD it’s fried, you should try using a variant of SBC with eMMC support. Like for example a Banana Pi M4 Berry or a Orange Pi 3B with eMMC module.
