Be sure to verify your drives when purchasing. Hope this helps!

@kulerkopf checking the head-flight-time it doesnt seem so bad. probably a hotspare which was never been written to. same here got 4 different drives all had an invalid warranty check and F.A.R.M Values exposed a PowerOnTime of more than 10.000 hours. However the Head-Flight time is very low, so i assume i’ll keep it, as i see no other options on the market now
I already checked the warranty, and it’s invalid for all of them (I also have 4).
Are you sure that the Head-Flight Hours weren’t reset together with the SMART values? Because mine are almost the same as the SMART Power_On_Hours (only a 3-hour difference).
The obvious difference that stands out to me is that I use Scale, while you are using Core. I assume that the tool in Core runs on an older version. According to the official smartmontools website https://www.smartmontools.org/, version 7.4 is available for FreeBSD, which, according to this Reddit post https://www.reddit.com/r/selfhosted/comments/1idlh8r/tool_to_verify_seagate_drive_authenticity_by/, is necessary to check the FARM values. However, I’m not sure if this version is available in the TrueNAS Core version you are using. I believe you can check the version of smartctl with smartctl --version.

smartmontools SVN rev 5530 dated 2023-08-01 at 11:00:21
smartmontools build host: x86_64-pc-linux-gnu
smartmontools build with: C++11, GCC 12.2.0
This is my output for reference.
Someone in the Reddit post mentioned that they connected their hard drive to a Linux machine without mounting it and were able to read the FARM values that way - maybe that could be an option for you as well. Otherwise, just go through the Reddit replies; maybe someone with TrueNAS Core/FreeBSD has already found a solution.
That was very helpful. The latest Truenas Core version uses smartmontools 7.2 so that explains it.
Is it possible to use a VM that runs the command on a Linux based OS? In any case, I will keep my eyes open for a good solution for Core users. Cheers.
The VM would need to have full access to the drives, which pretty much defeats the purpose of a NAS. I would rather shut down the NAS, boot a LiveUSB distribution to read FARM data, and go back to regular duties.
Thank you for pointing this out…For some reason my Truenas Core built was stuck in 13.0 U6 when searching for the latest update in the WebUI and it would sometimes give security updates, so I just assumed it was the latest version ._.
I installed 13.3 manually and that did it; I have smartmontools 7.4 and I just read my FARM log on my drives.
Thankfully the FARM values are identical to my SMART values and they all show 12k hours which is right.
Thank you guys for helping out, I appreciate the support!
returned all the Exos Drives and purchased a Iron Wolf Version which seems brand new.
i’ve a question to TrueNas Scale implemented SMART Test. I ran the LONG Test but there is no summary page or the output is very limited. Is there a GUI option to see the more details?
13.0 is the train on which CORE Enterprise runs.
13.3 is a “community only” curtesy version for those who wish to do a last update of their jails to FreeBSD 13.3/13.4; it is a manual update by design.
