Abstract

A method, apparatus and computer-readable medium for adjusting Predictive Failure Analysis (PFA) polling rates based on a temperature of an electronic device is presented. In one embodiment, the method includes the steps of by recognizing the danger that high temperatures pose to the HDD, adjusts PFA polling rates. In one embodiment, the invention includes the steps of setting a maximum temperature at which an electronic device (for example, a hard disk drive) can operate without damage; measuring a temperature of the electronic device; and increasing a frequency of Predictive Failure Analysis (PFA) operations as the temperature of the electronic device approaches the maximum temperature. The PFA operations include, but are not limited to, polling performance data that is being collected in real-time for the electronic device.
