Frage zu SMART-Werten

Blog Benutzer
Hallo zusammen,

bei eBay habe ich eine HGST Festplatte gekauft, die als "neu" angeboten wurde. Gerade bin ich etwas im Zweifel, ob nicht an den SMART-Werten herum manipuliert wurde. :rolleyes: Die Verpackung war auch etwas ungewöhnlich. Die Festplatte stammt aus dem Jahr 2013.

Hier mal die SMART-Werte:

Ich habe einen Selftest mit "smartctl -t long /dev/sdb".

Was mich etwas stutzig macht, sind die 22914 Stunden, die dort angegeben sind. Kann ich hier davon ausgehen, dass die Platte schon etwa 3 Jahre in Betrieb war?

Jap, zur Laufzeit von 22914 Stunden wurde ein SMART-Test ausgeführt.

Was mich auch stutzig macht ist, dass sich die Power_On_Hours zwischen den Tests negativ verändert, obwohl sie ja steigen müsste.

Code:
# 1  Extended offline    Completed without error       00%         7         -
# 2  Short offline       Completed without error       00%     22942         -
# 3  Vendor (0xb0)       Completed without error       00%     22914         -
# 4  Vendor (0x71)       Completed without error       00%     22914         -
Entweder kann da jemand Zeitreisen, oder die Festplatte ist nicht ganz koscher.
Die Festplatte bzw. die SMART-Werte wurden womöglich manipuliert.
