Bad assumption. HFS has a fixed block count, which means that for any disk
of any size, there can only be X blocks (I don't recall the value of X).
Hence the block size will be Disk_Capacity/X, and hence the larger the disk,
the larger the block size. HFS+ does not work this way, however IIRC there
is a max partition size of about 4 terabytes.

I don't recall any issues with file size inaccuracy on large volumes with
HFS, but there is a file size limit of I think around 2g.
