(28)SMART (X'B0)

This command performs operations for device failure predictions according to a subcommand specified in the FR register. If the value specified in the FR register is supported, the Aborted Command error is posted.

It is necessary for the host to set the keys (CL = 4Fh and CH = C2h) in the CL and CH registers prior to issuing this command. If the keys are set incorrectly, the Aborted Command error is posted.

In the default setting, the failure prediction feature is disabled. In this case, the Aborted Command error is posted in response to subcommands other than SMART Enable Operations (FR register = D8h).

When the failure prediction feature is enabled, the device collects or updates several items to forecast failures. In the following sections, note that the values of items collected or updated by the device to forecast failures are referred to as attribute values.
