This happens frequently with MCH when used as a server, especially with PLEX MS that writes constantly in indexing, logs and metadata. No drive manufacturer will warranty against data loss with a situation such as the consumer product that is MCH. The new firmware 8.12.0-178 and above will help because it will avoid using the KDD virtual file system as before, but the culprit is mainly the SMR drive which can be cloned and changed out and sometimes rescued but not easily by the consumer.
