Platte kaputt? Warum findest SMART nichts?

Hallo,

habe hier ein RAID1 mit zwei SAMSUNG HD753LJ.

Heute vormittag im Log:

Sieht ja zunàchst mal danach aus, als ob die Platte hinüber wàre. Aber:

SMART findet keinen Fehler. Müsste SMART nicht die Fehler mitgeloggt
haben?

Wie verlàsslich ist die SMART-Diagnose? Ich werde die Platte natürlich
trotzdem tauschen, aber es wàre interessant zu wissen, ob dieser
Widerspruch zwischen dem Syslog (also dem Kernel-Treiber) und SMART
erklàrbar ist, oder ob man sich auf die Ergebnisse von SMART
grundsàtzlich nicht verlassen kann?

Die beiden da oben würden mir schon ausreichen. Auch wenn
der "Qualitàtsindex" jeweils noch auf 100% steht.
