6.4.1 Introduction
Self-Monitoring, analysis, and reporting technology (SMART) is monitoring system that monitors device
condition based on the indicators reported by the device itself. This system is created to anticipate/predict
any failures that might happen before it actually happens in the hope that there is still time to take action.
This document is only created for the purpose to inform users about the SMART commands and SMART
attributes implemented by Silicon Motion, Inc, including the data structure returned by those command. For
more detail information on how to invoke the SMART command, please refer to the ATA specification since
the topic is outside the scope of this document. For the information, the current implementation is based on
the ATA-7 specification document.
6.4.2 SMART Command
The following table defines the SMART command set that is supported by SM2244/SM2250. Please note
that D1h and D3h are obsolete commands. Although obsolete, the interfaces are still provided to maintain
backward compatibility with the previous ATA specification.

respond to the command by returning normal output (provided the right command and parameters are

SMART Enable/Disable Attribute Auto-Save (D2h)

SM2244/SM2250, the auto-save feature is always enabled; regardless the disable function is invoked. This
will prevent SM2244/SM2250 to lose any information those might be critical for the device’s life indicators.
SM2244/SM2250 still responds by returning normal outputs when the command and right parameters are
executed.
SMART Save Attribute Values (D3h)
This command is obsolete starting from ATA-6 specification. The command interface is still supported for
backward compatibility with the older host implementing ATA-6. SM2244/SM2250 responds to the command
by returning normal outputs, provided the command and right parameters are entered. It is currently not
necessary to call this command since SM2244/SM2250 is saving the attributes values automatically. Please
refer to SMART Enable/Disable Attribute Auto-Save (D2h) for the reason of this auto-save.
SMART Execute Off-Line Immediate (D4h)
The purpose of this command is to immediately initiate any activities that collect SMART data or execute
self-diagnostic test routine in off-line mode or captive-mode depending on the given sub commands. The
offline data collection status, self-test execution status, and estimated time of completion for the off-line data
collection activity will be reported in the SMART data structure offset 362, 363, and 364 respectively. Please
refer to SMART Data Structure.
Although the interfaces are supported, however, SM2244/SM2250 does not currently have any off-line data
collection nor self-test defined in the firmware. Calling the off-line data collection sub-command will always
result in status value of 02h, which is “Off-line data collection activity was completed without error”. While
calling self-test sub-commands will always result in status value of 0, which means that “the previous selftest
routine completed without error or no self-test has ever been run”
The following sub command interfaces are currently accepted by SM2244/SM2250. Other sub commands
will result in command aborted error.

all the SMART command above will return command aborted error.

This command disables access to all SMART command operation. When the SMART operation is disabled,
accessing all the other SMART Commands (other than D8h and D9h) will return command aborted error.
SMART Return Status (DAh)
This command returns the reliability status of the device to the host. It will check the device’s attributes
against pre-determined threshold values and return the status result. If the attributes have reached the
threshold values, then the device will set the LBA Mid register to F4h and the LBA High register to 2Ch.
Otherwise, it will keep the original LBA Mid Register value of 4Fh and the LBA High register value of C2h.
Currently, SM2244/SM2250 only checks the total spare block available on the device against the minimum
spare block threshold. This spare block threshold value is set in the CID offset 0x2C.
