Apart from how many spare inodes you have, & the spare (root only accesible), mainly think block sizes (eg fsize bsize as shown by disklabel - though I see mine are now zero) efficiency depends on data type, a directory full of news & mail needs lots of little files, so use small blocks, films=movies are more efficient with large blocks. man tunefs # -b man newfs > > 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+.
