I was wrong about 32KB, it is 32 sectors of 512 when that is the block
size plus the MBR and header sectors, so 34 sectors at 512b, and yes
with 4K blocks you hit 24k.  Not sure if bigger sector sizes are likely
to happen at some point.  Maybe 32 or 64KB would be a safer starting
point and being a power of 2, slightly more likely to hit a disk aligned
block size.
