File system is full after using dd

[Lorenzo Torres]

Hello, I've run the dd command to wipe the data of an SD card:dd if=/dev/zero 
of=/dev/rsdb1c bs=1MAfter quite some time it crashed saying that the / 
filesystem is full and even after a reboot the same happens. Now I can't even 
run xorg because the fs is full. Any idea on why this happened? I have a 1TB 
NVME SSD as root disk and I have only a root partition as well as the efi 
partition on the root disk.Lorenzo Torres (https://sagittarius-a.org)
