TINY DEVICE(s) Mini ITX/PICO BOARDS AND MULTI-PARTITION SD CARDS

Usually I work with mini ITX boards on my sailboat,
especially with a 12VDC plug so I am trying to
create a "TINY DEVICE" that boots with an SD Card
and fit in an ultra-flat thin case.

I may try a PICO board if I get this working.

When I formatted a TERRABYTE SD CARD and
it shows as

/dev/sdc with FAT32 LBA type C partitions
/dev/sdc1 - primary, about 70gig and active
/dev/sdc2 - primary, about 400 gig
/dev/sdc3 - primary, about 400 gig
/dev/sdd1 - primary, about 150 gig

...using SUDO REBUILDFSTAB I only get

/mnt/sdc1

/dev/sdc2,sdc3,sdc4 don't show.

Is there another command  to light up
the other partitions?

I used
MKDOSFS -F 32 -n LXSD1 /dev/sdc1
MKDOSFS -F 32 -n LXSD2 /dev/sdc2
MKDOSFS -F 32 -n LXSD3 /dev/sdc3
MKDOSFS -F 32 -n LXSD4 /dev/sdc4
respectively.

Thanks for the tip.

Also, I noticed my laptop won't boot from
the SD Cards, but only USB so I tried a USB/SD Cradle
and it almost worked but couldn't get grldr or menu.lst
in time. I wondered if extending the USB DELAY in menu.lst
might help. Otherwise booting from SD CARD - the point
of this adventure, may prove impossible.

Hi, grandma!

I feel uncertain reminiscences about FAT and some frightening threshold of 130 GB. Why FAT?

FAT32 max partition size is 2T, but I'd still use something else.
