Seagate Hard Disk FARM Log
Since version 6.20.7, Hard Disk Sentinel Pro can detect and read the internal Seagate Field Access Reliability Metrics log (FARM) log of Seagate SATA hard disk drives (if supported by the drive). The Seagate Field Access Reliability Metrics log (FARM) log contains details about the hard disk drive, including but not limited to the power on time, number of heads, recording type (CMR / SMR), error counters / statistics and so.
To check the internal Field Access Reliability Metrics log (FARM log) of the Seagate drive, please select the drive and use the Disk menu -> Device Specific Information function which reads the internal error logs, test logs and the FARM log - so you can examine all details:
To make things very simple and easy, Hard Disk Sentinel Pro automatically verifies the accuracy of the power on time value reported by the drive via "normal" S.M.A.R.T. attribute and compares to the power on hours value reported by the Seagate FARM log and displays both values automatically on the top of the window and the results:
if the value is correct and accurate
if the power on hours value altered/cleared/reset (and what is the difference, eg. how long the drive worked before the value reset)
In addition, the FARM log contains several information about the drive lifetime, operation environment statistics like temperature, power use, humidity (if supported by the drive). The following example is a complete Seagate Field Access Reliability Metrics log (FARM log) saved from a Seagate ST14000NM001G-2KJ103 SATA hard disk drive:

Looking forward to detect and report additional details and ideally hard disk drives of other manufacturers will provide same level (or similar) details like the Seagate Field Access Reliability Metrics log (FARM log) Hard Disk Sentinel can detect from the supported Seagate hard disk drives.
