How did you copy the files?
There have been some changes wrt filesystems. Too see if they have
anything to do with it, please try the following:
- run a 3.9 (or 3.8 if you do not have that) release kernel, and check
the numbers.
- umount the filesystem and run fsck -f on /dev/wd0d
- remount and check nunbers - go back to the snap kernel and repeat.
oh and report the output of df without -h, I like to see the raw numbers.
