when the attribute exceeds the threshold.

Current attribute value

The current attribute value is the normalized raw attribute data. The value
varies between 01h and 64h. The closer the value gets to 01h, the higher the
possibility of a failure. The device compares the attribute values with
thresholds. When the attribute values are larger than the thresholds, the
device is operating normally.

Attribute value for the worst case so far

This is the worst attribute value among the attribute values collected to date.
This value indicates the state nearest to a failure so far.

Raw attribute value

Raw attributes data is retained.

Failure prediction capability flag

Bit 0: The attribute value data is saved to a medium before the device enters

power saving mode.

Bit 1: The device automatically saves the attribute value data to a medium

after the previously set operation.

Bits 2 to 15: Reserved bits
