DESCRIPTION
ID
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.
Attribute
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.
Value
This is a value that corresponds to the Raw Data. Compare this with the Threshold.
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.
Worst
This is the lowest value attained by the hard disk since S.M.A.R.T started its assessment of
the hard disk.
Threshold
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.
Type
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.
