Hallo,
Titel sagt eigentlich schon alles, sobald ich eine Imagedatei *.dmg auf mein NTFS Laufwerk kopiere wird diese nicht mehr lesbar. Imagemounter sagt die Image-Daten wären defekt.
Was kann ich dagegen tun? Wäre auch schön wenn es noch eine Möglichkeit gäbe meine schon kopierten Imagedateien zu retten.

MfG

Terminal output von hdiulti imageinfo, wie es scheint gehen Partitionsinformationen verloren

Hier die defekte Imagedatei:
