2.  dd if=/dev/zero of=/Volumes/tank/100GB-file bs=1m count=102400
3.  du -s -h /Volumes/tank/100GB-file

What is the expected output? What do you see instead?
Should see

so does du show file size (what it's supposed to be) or how much space it 
actually takes on the drive (ie, compressed down to 512 bytes) ?
