S.M.A.R.T. Technology
Self-Monitoring Analysis and Reporting Technology or S.M.A.R.T is a diagnostic method initially developed by IBM and used to determine or prevent failures in hard disks (Predictive Failure Analysis). The technology was designed in order to predict or determine the cause of breakdown for IBM disks, but in the end it became widespread and popularly known as S.M.A.R.T.
Large manufacturers include this technology into their hard disks. S.M.A.R.T. analyzes a number of mechanical attributes. Such analysis allows determining incorrect disk operation before its complete failure as well as the cause of such failure.
How To Correct a S.M.A.R.T. Error
In spite of S.M.A.R.T. allowing predicting future problems, most of them are impossible to prevent. Therefore, S.M.A.R.T.is a technology which is often there to warn the user of the hard disk soon to break down. S.M.A.R.T. values cannot be corrected and there is no need to spend time on that.
If you don’t replace the hard disk, the error window will appear again and again. In this case, the only justified action would be saving data from the disk sectors which are still available. After complete breakdown, data on such disk cannot be read by any software. That is why your first step should be taking your data elsewhere.
