Vor einiger Zeit wurde meine Hauptfestplatte sehr langsam. SMART-Tests schlugen fehl oder führten zu Fehlern, also kaufte ich eine neue.
Nun, meine sterbende Festplatte ist nicht völlig tot; manchmal funktioniert sie und manchmal reagiert sie nicht. Ich weiß nicht viel über Festplatten, ich habe zum Beispiel etwas über das Reparieren/Ausschließen fehlerhafter Blöcke gehört.
Ich bitte niemanden, darüber zu spekulieren, ob der Normalbetrieb des Laufwerks wiederhergestellt werden kann. Ich frage vielmehr, ob ich etwas tun kann, um dies zu versuchen.
Hier ist die Ausgabe von smartctl, die den SMART-Status zeigt:
$ sudo smartctl -a /dev/sdb
