Det är en räknare för hur många gånger som disken har parkerat huvet/spunnit ner disken för att antingen spara kraft eller i detta fallet då det är en laptop skyddat sig från en stöt.

Frågan är mer hur länge som du har haft disken, om den går upp mycket då laptopen står med strömmen i på ett bord eller så?

Talet i sig är inte högt, beroende på disk skälvklart är gränserna olika den som är i min har en gräns satt av tillverkaren att den skall klara 650.000 parkeringar så..

haft den 3 dagar , körde kanske 5h med batteri, vid test tillfället så hade jag AC.

Vad kan jag se Load_Cycle_Count ber s/min/h/dag?

PS. är detta korrekt eller har det stor skillnad om man kör med batteri eller inte?

600000 / 7 = antal min / 60 = antal timmar / 24 = antal dagar / 365 = antal år

antal år = 0,163 år!!!

Troligtvis ännu mindre. hours_power_on = 21
