Hey,

I think the problem that you are seeing is due to freebsd reserving some space for the root user.

Somewhere in the handbook is says when you format a drive there will be around 10% of the drive reserved for root.

I think you can change that number but you will have to look in the handbook for that.

Hope this helps
