S.M.A.R.T. drives are designed to monitor specific parameters of their own performance, such as the rate of read-write errors, and issue an alert when these parameters indicate a potential problem. (Approximately 60% of hard disk failures are predictable.) The alert can be sent to the user and - Lenovo PC 300PL | Technical Information Manual 6275, 6285 - Page 51
