Ohjelman käyttö ei ole tuttu, enkä ole aiemmin tarvinnut tätä, joten viisaammat voinevat valaista minua.

Ja tiedosto sdf.smart.txt sisältää seuraavaa...

Noilla tiedoilla vaikuttaisi olevan kunnossa.
Kohdat 1,5,197 (attributes) kertovat aika paljon. Luvut on hyvä olla pyöreät 0.

CrystalDiskInfo näyttää samat tiedot ja se sisältää myös indikaattorit kullekin luvulle eli siitä ymmärtää pikaisella vilkaisulla onko joku luku pielessä vai ei.

Jos tosissaan haluaa varmistaa jotain, niin kannattaa käyttää kahta kolmea sovellusta samojen arvojen tuottamiseen ja tehdä niiden perusteella johtopäätös.
Tai jatkaa hutkimista.
