Learned something new there.  Thanks!

Agreed.  I just want a big chuck of storage (in this case the 2.0 GB that
I paid for, sigh...) and I don't care what format it is in.  As I said, I
am happy with FAT16 as long as I can use all (approximately) 2.0 GB of it.

This is something I will try.

Okay.  This is worth a try.

This is not for use in a camera.  It is just a quick and dirty way for me
to grab (about) 2.0 GB from one FreeBSD system and plop it onto another.

This SD card was purchased from a reputable firm in New York whose name
you would recognize were I to mention it.  I have had nothing but good
experiences buying from them in the past (many years > four).
