Your image is itty-bitty here in Lemmy-land, at least, but a dead SD card on HA is… unsurprising.
It might be recoverable if you plug it into a linux box and try to extract the data, but as for recovering it, it’s the same as a dead hard drive: you might get data back, but the physical media is trash.
You probably want to NOT use a SD card and pick any other option (USB real SSD, NVMe hat, etc.) because, well, SD cards are not very good at this kind of use case. (HA writes a lot of historical data, and is basically always chattering away on the disk.)
This is one of the main reasons why I’ve been a boring stick in the mud and stuck to com/net/org domain names for stuff I’m that I intend to use for anything that’s going to be around for more than a short period.
Odds are they’re not going to end up vanishing due to things utterly outside the control of, well, anyone or get sold to a horrible steward of them that jacks up prices insanely or does other stupid shit.
I will admit to owning a few .us domains, but as a US-ian, if the .us TLD vanished, I’m pretty sure my domain names would be very, very, very far down the list of shit I’m actually concerned about at that moment.
