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?
If you’re that paranoid about it, then just physically destroy the drive.
I work for an it department who resells their old stock online, we scrub the disks before sales, physical destruction is not possible.
That’s the companies decision and they should understand the risks.
