If the device is in the process of performing its off-line data collection activities and is interrupted by a STANDBY IMMEDIATE command from the host, the device shall suspend or abort its off-line data collection activities, and service the host within two seconds after receipt of the command. After receiving a new command that causes the device to exit a power saving mode, the device shall initiate or resume off-line data collection activities without any additional commands from the host unless the device aborted these activities.

If the device is in the process of performing its off-line data collection activities and is interrupted by a SMART DISABLE OPERATIONS command from the host, the device shall suspend or abort its off-line data collection activities and service the host within two seconds after receipt of the command. Upon receipt of the next SMART ENABLE OPERATIONS command the device may, after the next vendor specified event, either re-initiate its off-line data collection activities or resume those activities from where they had been previously suspended.

If the device is in the process of performing its off-line data collection activities and is interrupted by a SMART EXECUTE OFF-LINE IMMEDIATE command from the host, the device shall abort its off-line data collection activities and service the host within two seconds after receipt of the command. The device shall then re-initiate its off-line data collection activities in response to the new EXECUTE OFF-LINE IMMEDIATE command.
