Advice on 'new' Seagate Ironwolf disc FARM data (zerobytes.monster)

I've just purchased a supposed to be new Seagate Ironwolf. The FARM data reported by SMARTmon Tools reports power on hours as 11925 but spindle power on hours and head flight as 0. Hardware resets shows 3. As I understand it FARM data can't be reset so I'm wondering if there is something janky in how that value is reported or, I have a disk that's been used a hot spare for over a year or they just weren't able to reset that particular metric and the others have been zeroed. Any insights would be appreciated as I'm curious.

On another note I brought this from Amazon with eyes open as to the likely situation. It cost me £220 and a comparable Western Digital disk from a more reputable supplier would be closer to £400. For the usage I have planned for this disk that seems a worthwhile risk and for similar overall costs I could have the data on two drives for redundancy. The down side is if they die in a couple of year then my costs work out higher. When I upgrade my NAS backup storage for non and hard to recover data I'll probably be going with WD Red's again.
