10.8.1 Attributes Attributes are the specific performance or calibration parameters that are used in analyzing the status of the device. Attributes are selected by the device manufacturer based on that attribute's ability to contribute to the prediction of degrading or faulty conditions for that particular device. The specific set of attributes being used and the identity of these attributes is vendor specific and proprietary. 10.8.2 Attribute values Attribute values are used to represent the relative reliability of individual performance or calibration attributes. Higher attribute values indicate that the analysis algorithms being used by the device are predicting a lower probability of a degrading or fault condition existing. Accordingly, lower attribute values indicate that the analysis algorithms being used by the device are predicting a higher probability of a degrading or fault condition existing. There is no implied linear reliability relationship corresponding to the numerical relationship between different attribute values for any particular attribute. 10.8.3 Attribute thresholds Each attribute value has a corresponding attribute threshold limit which is used for direct comparison to the attribute value to indicate the existence of a degrading or faulty condition. The numerical value of the attribute thresholds are determined by the device manufacturer through design and reliability testing and analysis. Each attribute threshold represents the lowest limit to which its corresponding attribute value can be equal while still retaining a positive reliability status. Attribute thresholds are set at the device manufacturer's factory and cannot be changed in the field. The valid range for attribute thresholds is from 1 through 253 decimal. 10.8.4 Threshold exceeded condition If one or more attribute values are less than or equal to their corresponding attribute thresholds, then the device reliability status is negative, indicating an impending degrading or faulty condition. 10.8.5 S.M.A.R.T. commands The S.M.A.R.T. commands provide access to attribute values, attribute thresholds and other logging and reporting information. 10.8.6 S.M.A.R.T. operation with power management modes The device saves attribute values automatically on every head unload timing except the emergency unload, even if the attribute auto save feature is not enabled. The head unload is done not only by Standby, Standby Immediate, Sleep command, and Hard Reset, but also by the Standby timer. So it is not necessary for a host system to enable the attribute auto save feature when it utilizes the power management. If the attribute auto save feature is enabled, attribute values will be saved after 30 minutes have passed since the last saving, besides above condition. 10.9 Security Mode Feature Set Security Mode Feature Set is a powerful security feature. With a device lock password, a user can prevent unauthorized access to a device even if it is removed from the computer.

Travelstar 5K100 (Serial ATA) Hard Disk Drive Specification

10.8.1

Attributes

Attributes are the specific performance or calibration parameters that are used in analyzing the status of the device.

Attributes are selected by the device manufacturer based on that attribute's ability to contribute to the prediction of

degrading or faulty conditions for that particular device. The specific set of attributes being used and the identity of

these attributes is vendor specific and proprietary.

10.8.2

Attribute values

Attribute values are used to represent the relative reliability of individual performance or calibration attributes.

Higher attribute values indicate that the analysis algorithms being used by the device are predicting a lower proba-

bility of a degrading or fault condition existing. Accordingly, lower attribute values indicate that the analysis algo-

rithms being used by the device are predicting a higher probability of a degrading or fault condition existing. There

is no implied linear reliability relationship corresponding to the numerical relationship between different attribute

values for any particular attribute.

10.8.3

Attribute thresholds

Each attribute value has a corresponding attribute threshold limit which is used for direct comparison to the attribute

value to indicate the existence of a degrading or faulty condition. The numerical value of the attribute thresholds are

determined by the device manufacturer through design and reliability testing and analysis. Each attribute threshold

represents the lowest limit to which its corresponding attribute value can be equal while still retaining a positive

reliability status. Attribute thresholds are set at the device manufacturer's factory and cannot be changed in the field.

The valid range for attribute thresholds is from 1 through 253 decimal.

10.8.4

Threshold exceeded condition

If one or more attribute values are less than or equal to their corresponding attribute thresholds, then the device

reliability status is negative, indicating an impending degrading or faulty condition.

10.8.5

S.M.A.R.T. commands

The S.M.A.R.T. commands provide access to attribute values, attribute thresholds and other logging and reporting

information.

10.8.6

S.M.A.R.T. operation with power management modes

The device saves attribute values automatically on every head unload timing except the emergency unload, even if

the attribute auto save feature is not enabled.

The head unload is done not only by Standby, Standby Immediate,

Sleep command, and Hard Reset, but also by the Standby timer.

So it is not necessary for a host system to enable

the attribute auto save feature when it utilizes the power management.

If the attribute auto save feature is enabled,

attribute values will be saved after 30 minutes have passed since the last saving, besides above condition.

10.9

Security Mode Feature Set

Security Mode Feature Set is a powerful security feature. With a device lock password, a user can prevent

unauthorized access to a device even if it is removed from the computer.

New commands are supported for this feature as listed below:
