Re : Copie de fichier qui n'en fait qu'a sa tête.
Répondre #11 –
Bonjour,
Parfois l'image saute, parfois le fichier est illisible, parfois rien n'est visible à l'oeil nu.
J'ai essayé de copier avec dolphin, cp et scp. Le problème est toujours là...
Parfois même mes fichiers sont identiques si je les compares tout de suite après la copie puis différents quelques minutes après...
En cherchant un peu je suis aussi tombé sur ça quand je fais un dmesg (il semblerait que ce problème arrive lorsque l'ordinateur passe en mode hibernation)

Je penche de plus en plus pour un rootkit ou autre saloperie de ce genre ( je n'ai pas que des amis sur internet ) comment on peut procéder pour vérifier de ce côté là ?
