SMART Screen

Use this screen to view indicators of your NSA's hard disk(s) health.

Self Monitoring, Analysis, and Reporting Technology (S.M.A.R.T) detects and reports the reliability of hard disks using standard indicators (called "attributes"), to help you anticipate possible disk failures.

Note: The fields included the screens may vary depending on the hard disk that you use.

S.M.A.R.T. Information
Brief Summary	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.
Full Summary	Select a volume and click this to display more detailed information about the volume.
The table lists your hard disks. Click a column's heading to sort the entries by that criteria.
Status	This shows the condition of the hard disk volume.
Name	This shows the name assigned to the hard disk.
Temperature	This shows the temperature of the hard disk in degrees celsius.
Performance	This shows your hard disk's performance.This displays: Good - This shows when you compare each Value with the Threshold Value and all the Value is greater than the Threshold Value. Bad - This shows when you compare each Value with the Threshold Value and at least one Value is less than or equal to the Threshold Value.
Type	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.
Volume Name	This shows the name of the hard disk volume.
Model Name	This shows the factory model of the hard disk.
Capacity	This shows the total hard disk space of the hard disk volume.

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-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.
Updated	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.
When Failed	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 displays if the attribute is not failing now and has never failed in the past. FAILING_NOW: This displays if the attribute's current normalized value is less than or equal to the threshold. In_the_past: This displays if the attribute's current normalized value is greater than the threshold but the worst recorded value is less than or equal to the threshold.
Raw Value	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.
