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?
shred
Can also be used from KDE Partition Manager.
Use LUKS encryption in the future.
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!
