  • My Pi-Hole sd card became corrupted or something. Luckily I had a clone taped to the lid so it was just a case of swapping cards and it was like nothing had ever happened.

    I noticed recently it was slower than usual over ssh and after running sudo shutdown -r now after updates, it wasn’t always coming back online. Last night it wouldn’t reconnect at all.

    I reformatted the card using the official sd formatted tool and re-imaged it with raspbian lite and there were no errors. I’m guessing it just overwrote a block or something and refused to boot normally. It’s been in 24/7 use for nearly a year but not under heavy writes.

    Always have a backup ready, folks.

  • Check your power supply, the Pi doesn't regulate the 5v passed through to the SD controller, I've read that SD card damage is quite common with iffy supplies.
