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?
Just keep in mind that you can’t wipe the bad sectors that have been remapped. That’s unlikely to be an issue for a personal drive, but something to consider if it held particularly sensitive information.
