Bon, voila, un disque maxtor acheté en 2004, est en train de me pêter dans les doigts, il est branché sur l’ide d’un fixe, en slave:
- il y a quelques jours, le disque n’est pas reconnu au démarrage. Je dois rebouter pour qu’il le soit.
- ce matin, le système ne démarre pas, le boute reste bloqué sur un message d’erreur concernant /dev/hdb? et le disque en question fait clac clac de temps en temps. J’éteins je débranche hdb et reboute, démarrage sans soucis.
- je rebranche alim et ide sur le disque fautif, je reboute, et c’est OK.
Depuis, je n’ai pas osé éteindre la bécane. Je n’ai pas de quoi sauvegarder les données pour le moment… En gros la question que je me pose est “est-il plus prudent de laisser la bécane allumée jusqu’à ce que j’ai de quoi sauvegarder le bazar ou je peux éteindre la bécane et croiser les doigts?”
