+**NOTE:**  **FARM** (Field Accessible Reliability Metrics) is only supported on Seagate drives.
+To check if a disk is really new(ish), compare the **Power_On_Hours** vs. **"Power on Hours"** in the two results.
+  * Other values that can also be checked, include **"Head Flight Hours"** and **"Power Cycle Count"**; they should also roughly match what you would expect from a hard disk of a certain age.
+  * All near zero, of course, for a factory-new hard disk.
