It doesn't need to boot. And the 3rd member doesn't need to autodetect, although I do want to be able to mount it independently if needed. Should it work to use the raw disk instead of a partition?
thats by "cylinder", which is an old MSDOS legacy thing. I believe parted and probably some other programs let you partition by sector instead.

so, a 'cylinder' is 8225 kbytes per that. simply cutting that down by a few kbytes will get you on your 4K boundary. right now a cylinder is 255*63 = 16065 sectors. which is most certainly not divisible by 8 (8 512 byte sectors is 4K bytes)
