===== Smartctl =====

<code bash>
sudo apt install smartmontools
</code>

To use:

<code bash>
sudo smartctl -x /dev/sda
</code>

and

<code bash>
sudo smartctl -l farm /dev/sda
</code>

<WRAP info>
**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.

===== Locate =====

<code bash>
sudo apt install plocate
</code>

<WRAP info>
**NOTE:**  This maintains a database of all your files and is re-indexed once a day by default.
