DESCRIPTION
Select Brief Summary to display basic information about the drive and its
status.
Select Full Summary to display advanced details about the drive and its
status.
This field displays the identifier number of the S.M.A.R.T. attribute.
This field displays the text name of the S.M.A.R.T. attribute. See
6.9.9 on page 156 for a list of common S.M.A.R.T. attributes.
This field displays the S.M.A.R.T. attribute's flag.
This is the attribute's current (or most recent) normalized value. These
normalized values range from 1 to 254 and are almost always mapped so
higher values are better. Compare this with the threshold value.
This is the hard drive's worst recorded normalized value for this attribute.
Compare this with the threshold value.
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.
Attributes can be one of two types: Pre-failure (Pre-fail) or Old age
(Old_age).
Pre-failure attributes are ones that indicate imminent hard drive failure if
the attribute value is less than or equal to the threshold.
Old age attributes indicate end-of-product life from old-age (normal
wearing out) 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. If only means this if the current normalized
value of the attribute is less than or equal to the threshold.
This indicates when the hard drive updates the value for this attribute.
Always means the hard drive updates this attribute during normal
operation and during offline activities. Offline means the hard drive only
updates this attribute when no one is accessing the hard drive.
