Poor error handling
Poor error handling. I had an error in the source partition I was cloning. EaseUS did not handle this well. It reported that the target SSD was too small and aborted leaving the target SSD unrecognizable by both Windows and EaseUS. After a bunch of online research and resorting to cmdline tools, I recovered everything. EaseUS should have reported an error in the source SSD and then put the target back into a usable state.
