There are several industry studies which have shown that correlation between SMART data, predictions made based on the data and actual failure rates, is NOT that strong.possibly only correlated in less than a third of hard drive failures. these ratings need to be taken in context, or at least take with grain of salt. Once data is returned, then SOME programs that try to calculate and give a 'probability' of failure or life expectancy rating. There really isn't any enforcement to keep manufacturers in line as far as how their devices report. Ultimately, the manufacturer of the drive decides how and what to report back. In many cases, manufacturers themselves don't adhere to the same interpretation of what a particular data field means relative to their product. Users need to realize, this app (and similar ones) are dependent and/or influenced by several external factors.ġ) The information returned by SMART is open to interpretation.
