 >> Terminate command early due to bad response to IEC mode page
 A mandatory SMART command failed: exiting. To continue, add one or more '-T permissive' options.
 -------------------------------------------
 
 Apparently this does not happen with a SATA disk connected to the same controller.
 
 The command 'smartctl -T permissive -a /dev/da0' does show the rest of the information (see below); however, scripts that look for the string 'SMART is: enabled' cannot work even with this workaround.
