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 Name

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.

 

 

Flag

This shows a code that S.M.A.R.T uses to determine the current state of the hard disk.

 

 

Value

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.

 

 

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-failindicate 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.
