Using Balena Etcher 1.5.112 I get a failure at flashing a 128Gb SD card with an image created from a Raspberry Pi 128Gb SD card system.
Below are the snippets of the log output when the failure occurs (I’ve not included all of the log entries showing the successful writes up to the point of failure)
