Close but not quite. "Allocation block size grows by 0.5kb for every
32,767kb a partition is in size." Thus a 127mb partition would have
block size of 2kb, and a 135mb partition would have a block size 2.5kb.
OTOH, if all you are concerned with is block size, you might as well go
up to the next multiple of 32kb.
The quote above is from the documentation that comes with FWB's Hard
Disk Toolkit software. I'm suspicious of the number 32,767 -- I suspect
it ought to be 32,768.
