"ls -l" shows the exact size per file. 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.
