JMicron USB to ATA/ATAPI Bridge (0100) wird erkannt aber nicht die sich am Adapter befindende Festplatte.Seltsam ist das der Geräte Manager kein Medium erkennt. Mir ist auch nicht bekannt was sich auf der Platte befindet. Kann es sein das eine Partition fehlt. Geparted erkennt sie nicht. /fdisk -f ausgeführt. Gerät boot. Anfang Ende Blöcke Id System

Wer kann mir da weiterhelfen.

Habe ich gemacht, aber sie bleibt unsichtbar. Wie kann ich die reparieren. Vermutlich ist ein Superblock beschädigt.
