Eine 500-GB-Festplatte von Seagate Barracuda wurde kürzlich (vor einigen Wochen) einem Firmware-Upgrade unterzogen. (von CC38 bis CC49 Firmware Version) In der letzten Woche gab es auch Gewitter in der Gegend (einschließlich mehrerer Stromausfälle) Die Festplattenleistung hat sich vor zwei Tagen drastisch verschlechtert - kontinuierliche Lesevorgänge werden mit einem Durchsatz von ~ 800 KB / s durchgeführt. Ich habe versucht, den SATA-Anschluss zu ändern, ein anderes Betriebssystem zu starten, und verwende derzeit einen anderen PC, um die Daten der Festplatte zu sichern. Es scheint die Daten korrekt auszulesen, wenn auch unglaublich langsam. SMART Tools melden die bestandenen Tests:

Das Laufwerk muss offenbar ausgetauscht werden. Ich bin jedoch gespannt, welche Art von Schaden solche Symptome verursachen kann. Und warum wird dieser Schaden von SMART nicht gemeldet? Irgendwelche Vermutungen und Vorschläge sind willkommen.
