N5200 RAID 5 zerstört nach Migraion

Mein Thecus N5200 lief bislang mit 3 x 750 GB Festplatten im RAID 5 Modus.
Das Gerät war mit 1 TB Daten gefüllt.

Gestern habe ich eine 4. Festplatte gleichen Typs in Schacht 4 gesteckt und im Web-Interface die Migration gestartet.
Innerhalb der letzten Stunden erhielt ich per mail die folgenden Nachrichten vom N5200:

Nun habe ich das Problem, das gar kein RAID mehr angezeigt wird, auch nach Reboot nicht.
Kann man noch etwas retten? Kann das RAID recovered werden?

Hier die Daten meines N5200:
