Error information
(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.
When the failure prediction feature is disabled, 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.
