Select a hard disk volume from the list and click this to display information about the volume, such as the hard disk vendor, specific model, hard disk capacity and so on.

This shows volume type or file system that the hard disk is using, such as JBOD, PC Compatible Volume and RAID or FAT32, FAT16 and NTFS.

This shows the ATA version of the hard disk, which refers to an industry standard category for storage devices and connectors used.
|
|||||
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.
|
|||||||
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.
|
|||||||
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.
|
|||||||
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.

|
|||||||
This column indicates when (if ever) the attribute failed. An attribute has failed if the normalized value is less than or equal to the threshold.
|
|||||||
This is the attribute’s unprocessed raw data. These values show exact amounts of time or numbers of attempts or errors. The meaning to the raw values is specific to the hard drive manufacturer. Table 42 on page 156 has some information about whether a higher or lower individual raw S.M.A.R.T. attribute value is better.
