Synology DSM warns of Western Digital NAS drive lifespan.
Some Western Digital hard drives used in Synology NAS are flashing warning alerts triggered by the manufacturer's internal SMART data that reports usage stats and monitors health, after being powered on for three years. The warnings can get people to miss real issues like reallocated sectors. Western Digital's documentation indicates to flag for drive replacement as a recommended action at the three-year mark. The Synology subreddit has had discussions about how to disable WDDA and thereby ignore the warning to use all Synology features again.
