Hi Community,
ich habe seit ein paar Tagen eine externe USB3-Disk (HDD, Intenso 8TByte) die ich für Backups benötige. Die Disk schaltet sich alle 2 Minuten aus was natürlich lästig ist, wenn in kurzen Abständen die länger als die 2 Minuten sind, auf die Disk zugriffen wird.
Mir ist es bis jetzt nicht gelungen per hdparm den Powersleep zu verändern oder gar abzuschalten, obwohl das eigentlich funktionieren sollte.
Hier die SMART Infos:
