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.
shred or alternatively you can zero out all the bytes in a drive with dd if=/dev/zero of=/dev/<DRIVE>
The day job is Private Possum territory, so our agreement is
- we won’t send in drives
- we will send proof of destruction
and I’m sure it costs more, but we don’t have to worry about recovered user data.
Our stuff is also in those crazy-secure datacenters, too, so we don’t need to mess with crypto-at-rest.
dd if=/dev/zero of=/dev/disk
Use shred , it will automate multiple random passes, and finish with a zero pass.
Completely unnecessary. Overwriting the whole drive with zeros completely stops anyone from being able to recover anything
