Aide à l'analyse état du DD

Bonjour,
Suite à des problemes de DD, j'ai téléchargé HD Tune. Je vous soumets les différents rapports en espérant qu'on m'aide à comprendre si il y a un probleme matériel ou si je dois regarder coté logiciel.
Plusieurs partitions correctement defragmentées apres verification, espace libre suffisant et toujours ce probleme de transferts de fichier entre partition qui met un temps fou (10min au lieu d'une trentaine de secondes il y a quelquejours pour un fichier similaire)
