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.
