Tried remounting, if I did it correctly it didn’t work.
Here’s my steps:
guy@guy-HPElite ~ $ sudo cat /proc/mounts | grep KNOPPIX_8
/dev/sdf /media/guy/KNOPPIX_8 iso9660 ro,nosuid,nodev,relatime,nojoliet,check=s,map=n,blocksize=2048,uid=1000,gid=1000,dmode=500,fmode=400 0 0
guy@guy-HPElite ~ $ sudo mount -o remount,rw /media/guy/KNOPPIX_8
mount: /media/guy/KNOPPIX_8: cannot remount /dev/sdf read-write, is write-protected.
