Greetings,
i got my Seagate 12TB HDD today, and just launched the smartmontools farmlog, because i read some stories recently about Seagate HDDs.
It is an used HDD (open box, condition like new).
What do you think about those logs? The power on hours are likey correct, but the rest is so weird.
The Power on Hours of the FARM and SMART Log are identical.
Can FARM Logs be faked too?
I planned to use this Disk as a Backup for my NAS (4x4TB Raid5).
Thanks for your help guys.
