This command causes the device to immediately initiate the activities that collect SMART data in an
off-line mode and then save this data to the device's non-volatile memory, or execute a self-diagnostic test
routine in either captive or off-line mode.
The sector Number register will be set to specify the operation to be executed.

11.8.42.5.1 Off-line mode
The following describes the protocol for executing a SMART EXECUTE OFF-LINE IMMEDIATE
subcommand routine (including a self-test routine) in the off-line mode.
a) The device executes command completion before executing the subcommand routine.
b) After clearing BSY to zero and setting DRDY to one after receiving the command, the device will not set
BSY nor clear DRDY during execution of the subcommand routine.
c) If the device is in the process of performing the subcommand routine and is interrupted by any new
command from the host except a SLEEP, SMART DISABLE OPERATIONS, SMART EXECUTE
OFF-LINE IMMEDIATE, STANDBY IMMEDIATE or IDLE IMMEDIATE command, the device suspends or
aborts the subcommand routine and service the host within two seconds after receipt of the new
command. After servicing the interrupting command from the host the device may re-initiate or resume
the subcommand routine without any additional commands from the host.
d) If the device is in the process of performing a subcommand routine and is interrupted by a SLEEP
command from the host, the device will suspend or abort the subcommand routine and execute the
SLEEP command. If the device is in the process of performing any self-test routine and is interrupted by
a SLEEP command from the host, the device will abort the subcommand routine and execute the SLEEP
command.
