Hier ist eine Festplatte mit einigen seltsamen Mount-Fehlern auf einem Ubuntu-System. Ich bin mir nicht sicher, ob es an falschen Einstellungen in der fstab oder an einem tatsächlichen Hardwarefehler liegt. Ich führe smartctl aus, um den Status der Festplatte zu überprüfen. Ich habe keine Erfahrung mit dem Lesen der Ergebnisse, aber für mich sieht es so aus, als ob es schwerwiegende Probleme mit dieser Festplatte gibt. Aber die Leute in dem Laden, in dem die Festplatte gekauft wurde, sagten, die Festplatte sei in Ordnung. Hat jemand etwas Zeit, um mir Hinweise zum tatsächlichen Zustand der Festplatte und zur Bedeutung der SMART-Ergebnisse zu geben?

Antwort1
Die Parameterwerte werden auf 100 normalisiert, niedriger ist schlechter, und wenn sie unter dem angegebenen Schwellenwert liegen, wird dies als Fehler gekennzeichnet.
Sie weisen eine erhebliche Fehlerrate beim Rohlesen auf und die Festplatte hat alle ihr zu diesem Zweck zur Verfügung stehenden freien Blöcke bereits neu zugewiesen.
Die Festplatte funktioniert also nicht, aus welchem Grund auch immer. Sie können möglicherweise noch alles lesen (vielleicht hat der Typ im Laden das getestet), aber möglicherweise nicht mehr lange.
Erstellen Sie so schnell wie möglich eine Sicherungskopie, bevor es zu spät ist, und besorgen Sie sich eine neue Festplatte.

Stellen Sie für die Sicherung sicher, dass das Laufwerk schreibgeschützt ist. Der Superblock wird während des Mountens markiert. Wenn das Laufwerk ihn nicht schreiben kann, versucht, ihn zuzuweisen, und keine Reserven mehr zum Zuweisen hat, liegt ein Problem vor, das zu den von Ihnen erwähnten „seltsamen Mountfehlern“ führen kann.
(Ja, ich habe gelesen, dass Sie bereits eine Sicherungskopie erstellt haben, aber möglicherweise liest dies in Zukunft jemand anderes.)
