... Disk /dev/nvme0n1: 232.89 GiB, 250059350016 bytes, 488397168 sectors Disk model: WD Blue SN570 250GB ...

You'll see some other stuff like
/dev/nvme0n1p1, etc. These are the partitions on the disk. Those are not what you want to target if you're trying to wipe the "whole" disk. Instead, target the disk/device.

We're going to use the
shred tool. On Ubuntu derivatives, get it here:
sudo apt install secure-delete

It's great because it takes a while and does a better job. It takes 3 passes over the disk and writes pseudo random data over the whole thing.

shred -v /dev/nvme0n1
-v is for "verbose". Hasta data.
