Ich seh jetzt vorallem das er wie anfangs beschrieben nur 5 HDDs im Raid erkennt und Platte Nummer 6 wird als removed auflistet.
Wie kann ich jetzt herausfinden an welchem SATA Kanal Platte Nummer 6 haengt und an welchem SATA Kanal die Ersatzplatte dran ist. Das scheint mir der naechste Schritt zu sein.
