Take a look at man tunefs and the option -m Your issue is likely related to this. Besides that, UFS possibly uses more space to store metadata, etc... Haven't looked into this in long time, your inode size probably also affects total space available. When you were copying your data, were you doing it as root as normal user? Normal user won't be able to go beyond the reserved 8% (default), but root can, although this is bad a idea long-term. -Simon On Wed, 6 Jun 2012 11:32:50 -0300, Rafael Henrique Faria wrote: >Hi. >I'm transferring a disk from my MacBook to my FreeBSD server, it's a 500GB >3,5" disk in an USB enclosure. >As I was using it in MacOS, it was formated with HFS+.
