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 last five 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". 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
