I'm afraid I can't tell you what the raw numbers here mean -- except to
say that since the normalized values are all greater than the threshold
values, nothing is wrong.
This appears to be an older version of Maxtor's firmware, so perhaps they
are using the raw values in different ways than the current firmware.
And it may be that (in spite of being rate-type Attributes) these are
actually counters and hence always increasing.
Perhaps someone else can help explain this.
Cheers,
Bruce
