*4 Normalized 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.
*5 Worst ever normalized
This is the worst attribute value among the attribute values collected to date. This value
indicates the state nearest to a failure so far.
*6 Raw attribute value
Raw attributes data is retained.
*7 Off-line data collection status

If bit [7] is 1, it indicates that automatic off-line data collection function is enabled.
*8 Self Test execution status byte [16Bh]
Bit 0-3: Self Test remain time.
The values in these bits indicate the remaining percentage (0% - 90%) of Self Test until
completion by 0h-9h.
Bit 4-7: Self Test execution status
00h: Self Test has been completed normally. Otherwise Self Test has not
performed.
01h: Self Test has been interrupted by host.
02h: Self Test has been interrupted by the soft/hard reset from the host.
