6.3.2.8.2 SMART Device Error Log Reporting
The intent of SMART Device Error Log Reporting feature is to augment the SMART feature set to provide
additional diagnostic information on device that have generated error conditions. The device retains a
specified amount of previously executed commands, and write this data along with the time of a triggered
error condition to the existing SMART Read Logging Sectors.
The errors that device reported are gathered at all times the device is powered on except that logging of
errors when in reduced power modes “standby mode and sleep mode”. The last five errors that device
reported are gathered in summary SMART error log, and The last 255 errors that device reported are
gathered in comprehensive SMART error log. The summary SMART error log duplicates the five error
entries in the comprehensive SMART error log. A host can deliver the error information using the SMART
READ LOG SECTOR command. If SMART is disabled by the host, the device does not disable SMART
device error log. Disabling SMART will only disable the delivering of error log information via the SMART
READ LOG SECTOR command.
If a device receives a firmware modification, all error log data will be discarded and the device error count for
the life of the device will be reset to zero by client software “Download Utility”.
6.3.2.8.3 SMART Operation with Power Management Modes
When used in a system that is utilizing the power management feature set, a SMART enabled device
automatically saves its attribute values upon receipt of an IDLE IMMEDIATE, STANDBY IMMEDIATE, or
SLEEP command. If the device has been set to utilize the standby timer, The device automatically perform a
SMART SAVE ATTRIBUTE VALUES function prior to going from an Idle state to the Standby state.
6.3.2.8.4 SMART Function Default Setting
The device is shipped from the device manufacturer's factory with SMART feature disabled. The system
manufacturer or the applications shall enable SMART.
