I am running Linuxlite from a USB stick to fix a disc problem on a PC, but I cannot run "su" or "sudo" in a terminal because I do not have the superuser password.
Can someone tell me what it is?
Thanks
 
There is no sudo password if you are running LL live.

Running 
Code:
sudo cat /dev/zero > /dev/sdb
returns 
Code:
bash: /dev/sdb: Permission denied
where /dev/sdb is the failing hard disc that I want to clear.
 
You are most likely not the owner of that drive. Try to chown it first.
