event type. This field indicates the type of log.

POH/PC The tracking information for how many power-on-hours (POH) the

drive has had since it was shipped. This is how many hours the drive

on and off. POH is updated once every 60 minutes that the drive has

had power applied to it without interruptions.

power-on cycle. Each time a drive logs a Hard Event, it will increment

this count as well.

first time the media is used, to aid in tracking the media to the different events.

This ID does not correlate to any media ID used by application software.
