[Trisquel-users] Need help with safe partitioning (making files non recoverable)

[cyberdevoper]

Hi

I was just interested if i would install GNU/linux distro of personal choice  
and use in partition software to delete partitions,create new partition  
table(if possible) and re create partition with different size would this  
make files non recoverable to HDD/SSD or i would need to use specialized  
distro/bootable software for example parted magic to manage partitions and  
install OS afterwards?

Regards ;_)
