6TB HDD, UFS and SMB share, size problem

[stefanirulez]

Hi everybody, I'm a Nas4Free beginner and I've just installed a brand new 6tb hard drive in my NAS (that has nas4free v9.3.0.2.1283 installed).

All ok with the configuration; from a Windows PC in my LAN, I can read and write to the hdd without problems.

I've formatted my brand new hdd with UFS file system as I've read that it's a native file system fully supported in n4f.

Now I have the new hdd working and reachable using Samba. The hdd is actually empty and I've noticed that the free space is incorrect.

As you can see from the images below, it has a total size of 5,3TB that is correct. But why I can only use 4.9TB?

I dont think UFS file system has a huge overhead like this one or am I missing something?

Why are there about 400GB missing when I ask for free space? Do you have similar problem with your UFS file system drives?

Thanks in advance for your support!
