Reallocated sectors: what they mean in practice
Spare pools exist to absorb defects — your job is noticing when consumption accelerates.
Static low counts
Factory margins sometimes ship small non-zero values — trend matters more than day-one integers.
Monotonic climbs
Week-over-week increases indicate progressive surface or head issues — prioritize cloning while reads remain stable.
Pending sectors staging realloc
Pending counts represent unstable regions — watch them resolve into realloc or recover after rewrite attempts.
