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?
I assume in this context the benefit using LUKS is that even if someone does recover data from the drive, they’d just get encrypted data which is unreadable? If so, I hadn’t considered that before!
