The number in FAT12/FAT16/FAT32 is the number of bits per entry in the file allocation table, so it's the logarithm of the maximum number of clusters.  As a result, FAT16 can't be used for partitions larger than 2 GB; whether it's worth using FAT32 on smaller partitions depends on what type of files you have, but usually FAT16 will be more efficient.

Nobody uses FAT12 anymore except on floppy disks (and I guess hardly anybody uses those anymore.)  But doesn't Windows still use FAT16 by default on small partitions?

Maybe it would be useful for somebody to write a partitioning-and/or-formatting tool for the 84+ itself, since small USB disks are getting hard to find.

Can you give me a link to the full format of the FAT disks. I've been trying to find one, and can't seem to.

Wikipedia actually has a reasonably complete description of the filesystem data structures.  Is that sufficient?

For the record, my calculator has missing pages and runs msd8x, with a few graphical glitches, but usable all the same.

Yes, but I never liked wikipedia for full information like that. Is there a utility that I can look at the structure of devices I already have?

EDIT: I know about HxD, but something for mac/linux would be preferable.

dd and od or hd, perhaps?  I don't know about any newfangled GUI tools.

(E.g., to show the contents of your MBR in hex: dd if=/dev/sda bs=512 count=1 | hd)

Hmm, maybe I can look into USB8x again, then. I never got it to work, but it would be cool if I could use it.

Does anybody here know why msd8x doesn't support .8xk files? Does it have something do with signing? Or has it just not been programmed because it is too difficult?

Probably the difficulty part. Signing shouldn't be a problem AFAICT.

It will run and send single-page apps, but it doesn't have the OS validate them so they spontaneously delete after 16 runs :(
