ls -l  provides the file size in terms of number of bytes used. Not sure
which incantation of ls s needed to get allocated blocks.

when you INIT, i believe that by default, it places some of the
structures in the middle of the disk.

So the container file of say 1 gig would have some structure probably
written at the start and its middle, but nothing after. So the file
system would think the logical end of file is the highest byte written,
hence near the middle of the disk.
