    It's normal with a fusion drive.

    thanks...for your reply but why my MAC give me in the first line that the disc is full (available 115KB)? Just to understand...

    Your first screenshot shows Macintosh HD 'Logical Volume Group' (Gruppo volume logico) which is actually not a single drive, but  a group of two combined, so that most of OS X sees it as one large, somewhat faster, drive.


    The software/hardware that controls it, allocates most all of the space on both drives, and so Disk Utility reflects that.


    The second screenshot is a logical partition (something that things can actually write to), and Disk Utility shows that there is space available.


    Perhaps it's a bit like Apple reserving all the rooms in 2 hotels  & allocating them as they like; so when you ask the hotel manager (the volume group) - all are taken.

    Go to Apple reservations (logical partition), & they'll say there's plenty of space & put you (your data) somewhere suitable in one or both hotels.
