DESCRIPTION
This is the identification number used to tag a hard disk attribute.
This is standard across all S.M.A.R.T-enabled storage devices. However it depends on the
storage vendor which attributes it will allow S.M.A.R.T to diagnose.
This refers to an attribute of the hard disk that S.M.A.R.T can assess. Attributes describe
the hard disk's physical state, performance, wear-and-tear, and so on.
This shows a code that S.M.A.R.T uses to determine the current state of the hard disk.
This is a value that corresponds to the Raw Value. Compare this with the Threshold
Value.
S.M.A.R.T compresses the raw value(s) into a digit from 1 to 253, where 1 indicates the
worst scenario while 253 indicates the best scenario.
The values 100 or 200 usually represent the mean or normal value.
This is the lowest value attained by the hard disk since S.M.A.R.T started its assessment of
the hard disk.
This is the attribute's threshold value. If the attribute's current normalized value is less
than or equal to the threshold, the attribute has failed. An attribute value close to or below
the threshold indicates the hard drive is no longer reliable.
This shows S.M.A.R.T's assessment of the hard disk.
Old_age indicates end-of-product life from old-age (normal wearing out) if the attribute
value is less than or equal to the threshold.
Pre-fail indicate imminent hard drive failure if the attribute value is less than or equal to
the threshold.
Note that just because an attribute is of the Pre-fail type does not mean your hard drive is
ready to fail. It only means this if the current normalized value of the attribute is less than
or equal to the threshold.
