Je viens de découvrir que le cache du disque dur n'est pas actif par défaut sous Mint et que la fonction d'arrêt du disque en cas d'inactivité ne l'est pas non plus.
Pour activer tout cela il existe l'utilitaire Disques qui fait le café. Voici la manip :
1) Aller dans Menu > Accessoires > Disques
2) Sélectionnez votre disque (colonne de gauche)
3) Ouvrir les paramètres du disque sélectionné (raccourcis CTRL + E)
4) Activez et désactivez ce qui vous plaît dans chaque onglet (attention à ce que vous faites)
Et voilà (^_^)
Comment paramétrer parfaitement votre equalizer / mixer. C'est fou toute la différence que procure cette configuration !
