Running Seatools on a job lot of used disks, a WD Blue 2 TB came up as 0 power-on hours. It has Windows 10 installed (but no user files), so should be a few hours at least. The other SMART data looks plausible. I have used Seatools on WD drives before, and it always showed many hours for those.
Try CrystalDiskInfo or WD Data Lifeguard.
That way you can check if the SMART data is really wrong, or just Seatools has a mistake.
