Par avance, merci.

Re : Disque dur interne endommagé
Ton disque a 17.000 heures de vol et 1 "Current_Pending_Sector".
Il était à 43°C au moment de ton test.
1) Cela veut dire qu'il est prudent de le remplacer rapidement. Avant que son usure ne s'aggrave et que la conservation de tes données ne devienne ardue, voire en partie impossible.
Pour plus de sûreté des mesures, redonne les données SMART à partir d'une session live, mais il est probable que le secteur défectueux ne sera pas récupéré. Et il est certain que d'autres vont suivre.
2) Par ailleurs, quand tu auras changé ton disque n'oublie de surveiller sa température et de modifier, si besoin, ses réglages pour qu'il ne dépasse pas 40°.
A titre d'exemple, j'ai quasiment le même disque que le tien, et si j'oublie de lancer au démarrage :
sudo hdparm -B 240 /dev/sdasa température peut monter à 55° (et je n'ai pas flashplayer qui échauffe les disques).
Mais quand je lance cette commande, qu'il est possible d'automatiser, la température ne dépasse pas 41 °C, même en utilisation intensive.
Les têtes de lectures de ton disque, pendant sa vie, ne se sont mises au repos que toutes les 6 minutes en moyenne, d'où l'échauffement. (chez moi : 1 minute).
