That's a good result, not bad; those number count downwards.. that's
why the threshold is lower than the current or worst value.
See the manual page for smartctl for more information on interpreting
the output of the tool:
"Each Attribute also has a Threshold value (whose range is 0 to
255) which is printed under the heading "THRESH". If the Nor-
malized value is less than or equal to the Threshold value, then
the Attribute is said to have failed. If the Attribute is a
pre-failure Attribute, then disk failure is imminent."
Not reallocated sectors. I new disk has "zero" reallocated sectors.
