I’ve had this happen a couple of times: Sold a board on ebay that I’d tested with a couple of SSDs, working fine. Customer, or their tech, installs their board and it can’t find the SSD, despite trying multiple SSDs. Board gets returned - I try my SSDs and everything’s working fine. Is there something happening with a firmware clash on these? I know that there can be a clash between 2016 and 2017 SSDs, but there shouldn’t be an issue within the years, should there?
