A very short term power cut corrupted my SD card.
I formatted the card and installed a copy of the card, but could not SSH in to the pi. IPscan24 reported I had two pi’s on different ips, neither of which was accessible.
I changed the card for a complete new install on another card and that worked fine. Presumably something went wrong when I read the card back in to the PC using Win32DiskImager.
Is there a better way to copy an SD card?
Any recommendations for a ups system that can take over during short term outages.
