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.
You must log in or # to comment.
Try CrystalDiskInfo or WD Data Lifeguard.
That way you can check if the SMART data is really wrong, or just Seatools has a mistake.
SMART data is basically worthless.
