[smartmontools-support] smartctl / Airflow_Temperature_Cel, In_the_past-values

[Bruce Allen]

Hi Robert,

Before your fan malfunction, the highest temperature that your disk had
reached was below the design threshold.  During the fan malfunction,
your disk went above the design threshold temperature.  As a result, the
disk is now marked as having exceeded the "old age" failure threshold.
This is because the worst value "43" is below the threshold value "45".
However currently the value of 62 is well above the threshold.  So
currently the temperature is within the acceptable operating range.

If the drive has fluid bearings and is now acting OK, then you can
probably ignore this overtemperature in the past.  But for example if
you return the disk under warranty then it's possible that Seagate will
say that you have operated it under conditions not covered by the
warranty, and won't service/replace it.

I don't know how to interpret the "in the past" values.  Seagate might
tell you if you ask them.

Cheers,
	Bruce
