Thanks for that! You were "spot-on". Using that, I see:nl3prc wrote:i think you logged in as user pi so fdisisk is not working without sudo before it

So ~ this, now, is "sort-of" what I had expected (before beginning on this "journey", into Pi-dom).
A comment was made above, that a "full install" ("typical_single_OS") was 4GB or more...
and (correct me if I'm wrong) I was certain from the get-go that each of these 3 OS's could only consume some small fraction of that "disk area".
My question now is:
having typed "m" for Help, after seeing the above info, I now see:
[Generic] n > for "add a new partition"
t > for "change a partition type"
Create a new label <?< (should that say "table"?)
g create a new empty GPT partition table
G create a new empty SGI (IRIX) partition table
o create a new empty DOS partition table
s create a new empty Sun partition table
So : apparently, additional partitions CAN be made on these (32GB) cards.
IF a partition is made for "Storage", is it possible to make that area "viewable" by each (or "any") of the 3 OS's (mentioned previously)?
OR... might it be possible to do so if I erased these (6) cards and started from scratch...?
I am willing to accept that this is a "lost cause" IF, in fact, it is... but, I suspect that the answer is right in front of me, and I just can't see it because of my current state of "unfamiliarity".
Any and all help is greatly appreciated!
