Fujitsu MHY2100BS Status Flag, Current attribute value, Attribute value for the worst case so far

5.3 Host Commands

•Status Flag

Bit	Meaning
0	If this bit is 1, it indicates normal operations are assured with the
	attribute when the attribute value exceeds the threshold value.
1	If this bit is 1 (0), it indicates the attribute only updated by an on-
	line test (off-line test).
2	If this bit 1, it indicates the attribute that represents performance.
3	If this bit 1, it indicates the attribute that represents an error rate.
4	If this bit 1, it indicates the attribute that represents the number of
	occurrences.
5	If this bit 1, it indicates the attribute that can be collected/saved
	even if SMART is disabled.
6 to 15	Reserve bit

•Current attribute value

It indicates the normalized value of the original attribute value. The value deviates in a range of 01h to 64h (range of 01h to C8h for the Ultra ATA CRC error rate and communication error rate). It indicates that the closer the value is to 01h, the higher the possibility of a failure. The host compares the attribute value with the threshold value. If the attribute value is larger than the threshold value, the drive is determined to be normal.

•Attribute value for the worst case so far

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

•Raw attribute value

Raw attributes data is retained.

•Off-line data collection status
