It's not Etcher because you followed my dd-and-sync instructions, effectively identical to those from thepihut above if you also did their instruction to sync, and you got read EIO errors: twice at two different places. To narrow down what bit of hardware is at fault, continue to read from the now known-good card, writing to /dev/null, swapping bits of hardware in the chain between CPU and card, including cables. Each time, note the chain's contents and the result. A `success' doesn't mean the chain's good; you may have just got lucky given the EIOs aren't at consistent locations, but it adds weight to your deliberations once you've done a few different chains. A `fail' is hopefully with the same error as before; the location would be worth noting to ensure it keeps moving, i.e. it's not the card itself.
