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?

      Installing an operating system and enabling encryption won’t overwrite the data on the entire disk. Instead, it will only overwrite on the specific sectors on which this operating system was installed.

      Other “previous” data on the disk will remain intact and unaffected.

        I understand what you mean. The way I did it was a full disk encryption as an “external drive” so the whole disk was encrypted

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