POH/PC The tracking information for how many power-on-hours (POH) the drive
has had since it was shipped from Quantum. This is how many hours the
drive has had power applied regardless of the number of times it is turned
on and off. POH is updated once every 60 minutes the drive has had
power applied to it with no interruptions.
Power cycles (PC) is how many times the drive has experienced a power
on cycle. Each time a drive logs a Hard Event, it will increment this count
as well.
