The actual situation is attached as image.

The image shows 29GiB "usato". My guess the disk is still corrupted. My advice is: check it is not mounted with mount; run sudo mkfs.ext4 /dev/sdb1. After it has finished, unplug the disk and plug it back in. Assuming /dev/sdb1 is the right device!

The procedure you proposed worked like a charm. Unfortunately, I have the same issues (the disk has the key in the gparted screen).

Here si the /etc/fstab listing:

# /etc/fstab: static file system information.

# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).

Any more hints? Should I try to change the disk permissions?

For some reason "root" is the owner and there is no write permissions for users...

luigi@luigi-Aspire-MC605:/media/luigi/6d719155-2cd3-420e-be1c-b871ca32e4af$ sudo chmod a+w . should do it

I also had to apply a chown to get through. Thanks folks, not it seems working!
