Zoran, re Brandon's "won't understand it any more."
Dont despair & discard stick, you can rebuild the MBR: man fdisk
from memory start with fdisk -i -B /dev/da0 

sometimes I then remove & reinsert or even reboot, to make certain
the OS has the new numbers.  I don't recall I've needed to reduce
from FAT32 to FAT16.

Ive not read the uefi page as happily no boxes are uefi here,
but I've often created FAT32 partitions, my notes at
http://www.berklix.com/~jhs/src/bsd/fixes/FreeBSD/src/jhs/etc/devd/berklix.conf

The advice about letting the other native MS FAT device format if it will,
is quickest solution though.

PS Max size of FAT32 = 2TB

First, thanks all for replies!
After a bit of puzzling, I found that the problem was every Transcend
usb stick I have. They are all fine for mundane tasks and newfs_msdos
makes it able to work on freebsd. My music player was picky and has
something to say against. When I inserted old and forgoten Verbatim
drive, without making f32, it presented itself and files were ready
to play. Unbelievable.
Yep, I did fdisk step after I posted the question. No go on Transcend.
Might be hardware incompatibility or else. Btw, I always do just newfs
on back up usb disks and never had any problem, so far, on freebsd.
Once again, thank you for help.
