Hallo,

mein Schwiegervater hat einen iMac aus dem Jahre 2009, Intel Core 2 Duo 2,66 GHz.
Darin ist eine 320GB HDD von Western Digital verbaut (WDC WD3200AAJS-40H3A0). Deren SMART-Werte habe ich vorhin mal mit DriveDX ausgelesen.
Die Übersicht sah für mich als Laien soweit ganz gut aus, aber den Wert 195 Hardware ECC Recovered verstehe ich nicht. Könnt Ihr mir sagen, ob die Platte für ihr Alter noch okay ist oder kurz vor Exitus steht!?

Probleme macht das Gerät keine.

195 Hardware ECC Recovered
An sich kein kritischer Wert, aber ein Hinweis auf elektromechanische Probleme.
Die Spinup Time ist ja auch schon höher.
Solltest du halt früher oder später ersetzen.
Mach auf jeden Fall häufig Backups.
