S.M.A.R.T. monitors the main characteristics of the drive, each of which is assessed. Characteristics can be divided into two groups:
- parameters reflecting the natural aging of the hard disk (the number of revolutions of the spindle, the number of movements of heads, the number of cycles on-off);
- current parameters of the drive (height of heads above the disk surface, the number of reallocated sectors, seek time and number of errors.
Data is stored in hexadecimal format, called "raw values" and then converted to value - the value that symbolizes the reliability with respect to a reference value. Value is usually in the range from 0 to 100 (some attributes have values from 0 to 200 and 0 to 253).
A high score indicates the absence of changes in this parameter, or slow its deterioration. Low - about a possible failure in the near future.
A value less than the minimum at which the manufacturer guarantees trouble-free operation of the drive means the output of node failure.
Technology S.M.A.R.T. allows:
-monitoring of state parameters;
-the surface scan;
-the surface scan with the replacement of bad sectors on normal.
-It should be noted that the technology S.M.A.R.T. allows to predict the failure of the device due to mechanical faults, which is about 60% of the causes of hard drive crash. To predict the consequences of a power surge or mechanical shock S.M.A.R.T. is not capable.
Features of GSmartControl:
-automatically reports and highlights any anomalies;
-allows enabling/disabling SMART;
-allows enabling/disabling Automatic Offline Data Collection - a short self-check that the drive will perform automatically every four hours with no impact on performance;
-supports configuration of global and per-drive options for smartctl;
-performs SMART self-tests;
-displays drive identity information, capabilities, attributes, and self-test/error logs;
-can read in smartctl output from a saved file, interpreting it as a read-only virtual device;
-works on most smartctl-supported operating systems;
-has extensive help information.
Installation latest version into Linux Mint:
sudo apt install gsmartcontrol
You can configure the check disk at every boot of the system. Installing GSmartControl, in advance, you will know that soon your hard disk will die. Forewarned is forearmed!!!
