I run a node with a raspi using all the hardware the process on the umbrel site. I switched cases to a heat sinc/fan and like an idiot broke my MicroSD in the process.

I bought a new one, loaded the Umbrel OS, and plugged it back in thinking it would boot up again and it is not. Any tips on how to fix? I am fully prepared to format everything and redownload the ledger if I have to but I can’t even access anything

Just did, now getting error

failed to connect to external device

It gives me the option to restart or shut down. I tried both but still am stuck on this screen.

That have nothing to do with your mSD. Is clearly your external drive that is failing to connect.
