Temperatur

Temperatur

Hitachi

-H

Speziell für Hitachi Festplatten, lässt sich die Temperatur auslesen und anzeigen, ob dieser Wert im grünen Bereich ist. Besonders für sehr alte Geräte, oder welche, die kein SMART unterstützen (z. B. CF-Microdrives).

Beispiel

Temperatur eines 4GB Microdrives

# hdparm -H /dev/sdb

/dev/sdb:
 drive temperature (celsius) is:  26
 drive temperature in range:  yes

... einer Desktop Festplatte:

# hdparm -H /dev/sdc

/dev/sdc:
 drive temperature (celsius) is:  41
 drive temperature in range:  yes

Hier stimmt sie mit der von SMART übermittelten überein (RAW_VALUE)
