Also, have you ever copied to it, using dd,  an iso image

Yes, the F-21 XFCE Live spin, that's apparently what triggered this?

THAT's WHY it is read only.

If you want to EVER mount it as rw, then you have to
destroy what you have installed on it, by doing this as root:

dd if=/dev/zero of=/dev/sdh bs=4M
.
[root@box10 /]# dd if=/dev/zero of=/dev/sdh bs=4M
dd: error writing ‘/dev/sdh’: No space left on device
932+0 records in
931+0 records out
3906453504 bytes (3.9 GB) copied, 4.51131 s, 866 MB/s


That doesn't touch it either ...


It did work!!!
Now you must unmount it
with the -f option,
and run fdisk  or parted or gparted to partition it
as you see fit.
Then you must mkfs the specific partition you want to mount
as read/write.
After mkfs finishes, you can mount it.




When done, then you can use fdisk or gparted (or the text based parted)
to partition the sd card.
Once done, you can mount the partitions rw.
