The S.M.A.R.T. attributes are specific properties (parameters) of various parts of a hard drive. S.M.A.R.T. uses attributes to monitor the disk condition and to analyze its reliability (e.g.: the “Temperature” attribute indicates the temperature of the hard disk, the “Power-On Hours” attribute indicates the count of hours in a power-on state, etc.) Various manufacturers may use different sets of attributes.
