Hallo Leute!
Ich bin dabei mein PC zu erneuern. Ich installiere derzeit auf eine Festplatte, die ich vor kurzem von dem PC meiner Frau genommen habe, Debian 8. Dafür nutze ich einen anderen Rechner. Der Plan ist, sobald alles fertig ist, die Festplatte an meinem PC anzuschließen und das neue System genießen. So weit so gut, aber ich merke oft, dass der Rechner sehr langsam wird und, obwohl kaum zu tun hat, oft der Load relativ hoch ist (mal sogar bei 5). Insbesondere wenn ich vieles mit der Festplatte mache (zB: Synchronisierung der Daten und gleichzeitig andere Dateien schreiben, bzw. eine Directory auszulisten, wo gerade geschrieben wird), "hängt"...
Das gefällt mir eigentlich gar nicht, weiß aber nicht, ob das Problem bei der Festplatte oder bei dem Rechner ist...
Ich habe deswegen gerade smartctl aufgerufen und ist folgendes zu sehen:

Was ist eure Meinung? Soll ich mir Sorgen machen? Wenn das Problem nicht bei der Festplatte ist, hat jemand eine Ahnung, warum der Load so hoch ist, obwohl top und ps meinen, kein Prozess nutzt mehr als 0.0% der CPU?
