Bit 0 (pre-failure/advisory bit) - If the value of this bit equals zero, an attribute value less
than
or equal to its corresponding attribute threshold indicates an advisory condition where the usage
or age of the device has exceeded its intended design life period. If the value of this bit equals
one, an attribute value less than or equal to its corresponding attribute threshold indicates a
prefailure
condition where imminent loss of data is being predicted.
