Other SD card - Read-only file system

I’ve run into a problem. I can't do anything with my microSD card; the system refuses to mount it or perform any operations on it. It displays the same warning for any action I try to take.
Code: 
root@freebsd_res:/home/user # gpart destroy -F /dev/da0
gpart: geom 'da0': Read-only file system
root@freebsd_res:/home/user # gpart show
...
=>       63  250347457  da0  MBR  (119G)
         63       8129       - free -  (4.0M)
       8192  250339328    1  fat32lba  [active]  (119G)

=>       63  250347457  diskid/DISK-<ID>  MBR  (119G)
         63       8129                                 - free -  (4.0M)
       8192  250339328                              1  fat32lba  [active]  (119G)

root@freebsd_res:/home/user # gpart destroy -F /dev/da0
gpart: geom 'da0': Read-only file system
root@freebsd_res:/home/user # mount /dev/da0s1 /mnt
mount: /dev/da0s1: Read-only file system
root@freebsd_res:/home/user # gpart delete -i 1 da0
gpart: geom 'da0': Read-only file system
I even tried this:
sysctl kern.geom.debugflags=16
But did not help.

Any ideas how to work around this?
 
Does dd say something while trying to write?
I had cheap Ali fakes with planned eol after 10 writes or so...
 
Thanks for the quick response. It’s a genuine Samsung SD card. It was used in a dashcam. It looks like the card has indeed reached its write limit. The question is - can this protection be removed at all? Or is that the end of the road for it?
 
end of the road when the write limit is reached. Copy off any data that you want to keep, then toss it and invest in a new one.
