I'll have to answer the other questions later, . . .
I think that the cardboard is to protect the heads from banging into each
other.
With the door of the drive closed, the heads are close together, and can
hit each other if the drive is jarred.
They probably do help keep dust off of the working surfae of the head(s),
but I don't think that tat is the reason for them.
If you don't have one, and need to move the drive afound, or ship it,
although it's not quite as good, the full thickness of the jacket of a
disk will do. Just turn the disk 180 degrees, so that it's the full
jacket, not just the cookie between the heads. (For a Twiggy disk turn it
90 degrees)

That is
because you are writing "320K" disk in a 1.2M drive.
double step is to get 40 tracks instead of 80
Makes sense, thanks. I wasn't 100% sure if this was a 1.2M drive or not.
How difficult is it to change a drive? And could it go the other way,
upping a 360K stock drive to support 1.2M? I imagine it's not as easy as
jumper settings- but a matter of voltage divider maybe? I don't want to
void my warranty (joking!! :) ) I think I've heard of people altering
their drives, I just hadn't seen it done.
I guess another 5.25 related question comes to mind - when a new system was
delivered, they had (cardboard?) inserts into the drives. Was that more to
protect them during transport/delivery? Or a dust protection? or both? For
long term storage (maybe 6+ months?) should we put inserts back into our
5.25 drives?
