A Qnap NAS has a drive with some bad sectors, I want to RMA it, but before just want to figure out how to prepare a drive? It’s part of a raid 5 setup of 4 drives unencrypted. So I want to remove it and wipe it. Got a Linux machine I can use, but never done this before.

What are common Linux tools to do that sensibly?

    sudo dd if=/dev/urandom of=/dev/[sdx] bs=4096K status=progress

    Or for multiple passes:

    sudo shred -fzv /dev/[sdx]

    Change [sdx] to the drive you want to wipe, make sure you double check it’s the right one.
