ID Attribute Name Description Rational
12 Device Power
Cycle Count
This attribute indicates the count of full
hard disk power on/off cycles.
Normalized Equation:
100 - (PCC /
1024)
Normalized Value Range:
Best = 100
Worst = 0
Raw Usage:
[3-0] : Cumulative lifetime power cycle
count (PCC)
[6-4] : None (0x00)
The normalized equation for
Power Cycle Count decrements
by 1 for each 1024 power
cycle.
171 Program Fail
Count
Counts the number of flash program
failures.
Usage:
[3-0] : Program Error Count
[6-4] : None (0x00)
This Attribute returns the total
number of Flash program
operation failures since the
drive was deployed.
This Attribute is identical to
Attribute 181.
172 Erase Fail Count Counts the number of flash erase
failures.
Usage:
[3-0] : Erase Error Count
[6-4] : None (0x00)
This Attribute returns the total
number of Flash erase operation
failures since the drive
was deployed.
This Attribute is identical to
Attribute 182.
174 Unexpected
Power Loss
Counts the number of unexpected
power loss events, as determined by
the number of times PFAIL has been
asserted (or other criteria?).
Usage:
[3-0] : Unexpected Power Loss Event
Count
[6-4] : None (0x00)
This Attribute returns the total
number of unexpected power
loss events over the life of
the drive.
