Hello. I need to completely wipe a hard drive and make the data unrecoverable. How would Sup Forums approach this issue? Also, it must not take 20 hours to do it. It is 1TB 5400 rpm so I know it will take a while, but I just want to know the quickest way.

Install gentoo.

magnets

dban

Daily reminder cat is faster than dd.

boot into a linux live USB and run shred -fvuzn 3 /dev/sdx

Magnets.

do you have a hammer?
