There may also be differences if the file system types are
different between the systems (e.g. reiserfs vs ext3).
There is overhead on all file systems, so that a fresh, empty
file system will have less free space than one might expect based
on the size of the disk, number of sectors, and block size.
I would expect that a newly built file system would have more
available space after loading files from another system would
have a bit more free space, all other things being equal, because
new files would likely be in contiguous space, not spread about
as may happen with growing database files.
