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?
Unless the OS installer chooses to wipe the driver, which Debian’s (non-calamares) installer does.
