[Bruce A. <ba...@gr...>]

Just to follow through....

The key thing here is to IGNORE the huge numbers like:
18446744073709551615 =3D 2^64-1

They are "un-normalized" raw values.  In fact in hexidecimal notation
the number above is:
FFFFFFFFFFFFFFFF

which just corresponds to "all bits set".  I think I might modify smartctl
to not print this value... let me think abou it.

The thing to look at is the three numbers:
162   162   000

The first is the actual Attribute value (162)
The second is the lowest (worst) value ever recorded (162)
The third is the "fail" threshold (0).

So if the first number drops to zero, this means that a Usage (old-age)
attribute is failing.  If the second number drops to zero, this means that
it has failed in the past.
