| Outline of Final Research Achievements |
It is required to predict the failure of the hardware of the computer system, while the system has become large scale. We analyzed the prediction of hard disk failure by machine learning of S.M.A.R.T. information on hard disk. A so-called positive predictive value (PRE) was used as an evaluation index. As a result, it was observed that the closer the day of failure is, the more unique signs affecting PRE appear. In addition, by improving the detection accuracy by machine learning of S.M.A.R.T. information, it was shown that prediction of disability can be expected with considerably high precision. It was found that the detection power of the judging machine during the period close to the number of days before failure was high.
