[Trisquel-users] Erasing Harddrive.

[deavmi]

So I burned Trisquel ISO to a disk using InfraRecord on Windows 8.1 and then  
I am using that to install Trisquel. But I cannot securely erase my whole HDD  
using Trsiquel, for some reason fedora's tool for drive erasing just works, I  
am currently doing so with the "ATA Enhanced Erase" option as compared to the  
"overwrite with zeroes option".

Which option for erasing should I be using?
