Can't mount sd card

I can't seem to figure how to mount an old 2GB sd card I had lying around from years ago. I forgot what I had on it... Using Debian 11 with KDE 5.20.5 * It's not recognized or mounted when insterted (other cards are, after restarting Dolphin several times, apparently a kde bug...) * When trying to mount manually (also tried with

-t vfat/exfat

):

sudo mount /dev/mmcblk0p1 /mnt/sdcard/
    mount: /mnt/sdcard: wrong fs type, bad option, bad superblock on /dev/mmcblk0p1, missing codepage or helper program, or other error.

* parted output:

Warning: Unable to open /dev/mmcblk0 read-write (Read-only file system). /dev/mmcblk0 has been opened read-only.
    Model: SD 00000 (sd/mmc)

* made a backup with

, that worked, now I have 2GB file on my hdd. * Also tried mkfs.vfat and mkfs.exfat, both complain thye can't open since it's read-only file system *
