New? Hmm ...

This disk is from Deskstar 7K1000 series, released ~2007.

Run a short self-test (smartctl -t short ...) and wait a few minutes for 
completion. Compare the Power_On_Hours raw value with the 
LifeTime(hours) value from the self-test log.

If both match, the power on time is probably correct (4 years + 10 month).
