Problema mount HD esterno WD

[somp66]

Buona sera a tutti
Ho un problema con un Hd esterno (marca WD), in pratica quando lo collego al pc mi da il seguente errore:

Codice: Seleziona tutto

Error mounting: mount exited with exit code 12: Failed to read last sector (3907027119): Invalid argument
HINTS: Either the volume is a RAID/LDM but it wasn't setup yet,
   or it was not setup correctly (e.g. by not using mdadm --build ...),
   or a wrong device is tried to be mounted,
   or the partition table is corrupt (partition is smaller than NTFS),
   or the NTFS boot sector is corrupt (NTFS size is not valid).
Failed to mount '/dev/sdc1': Invalid argument
The device '/dev/sdc1' doesn't seem to have a valid NTFS.
Maybe the wrong device is used? Or the whole disk instead of a
partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?

Premetto che all'interno si trovano files caricati da Windz ma prima di staccare l' HD ho fatto: Rimozione sicura dell'hardware.
Cosa posso fare per montare il mio HD?

Grazie

P.s. Ubuntu lo riconosce come da immagine allegata:
