Let’s say that you get a brand new 2TB/4TB/8TB/XXTB HDD, and you want to use it as a safe backup device.
That means you want to encrypt everything ...
For further actions, you may consider blocking this person and/or reporting abuse
For security it's better to write the disk with
/dev/urandomas with zeroing it can be recoverable, at least HDDs in which the bit retains partially the orientation.You are right, but I wanted to provide a compromise between security and time spent formatting the drive.
You can use
/dev/urandombut need to be prepared to spent ~3 days waiting for the drive to be filled with random bits.That's true, but its always worthy leaving a brick when resigning hahahahaha
Very useful, thanks!
A little off topic, I know but how did you set a fb:image meta for your post?
Er... I don't know? I just uploaded it and then set it as cover_image in the front matter list for this article.
Does that answer your question?
It actually does, thank you. I was unaware of this variable.
No problem, glad to be of help! :)
Any tips on choosing a secure passphrase?
Yes, of course, there is a XKCD for that!

Basically, don't trouble yourself with something hard to remember like this:
tH15-iz_my_pa55phras0rzYou should pick something easy to remember with multiple words like:
hey, you won't be able to guess this one even if you try, don't you agree?... or something like that. :)
