I have an old hard disk that I want to completely format. I have found online that the windows quick format deletes the partition table and labels all the data as "Available Space", but the data will remain and can be recovered with some recovery tools.
I have also read the windows long format will overwrite every piece of data with zeros amongst other things. But, despite this, some people will do this process several times or even use junk data instead of zeros.
For those who don't know the windows formatting is the formatting that can be seen when right clicking on a disk in the windows file explorer where it says format... (at least on windows 11).
My question, from a security point of view: Should hard disks be long formatted multiple times or is just one time enough? And what's the benefit of doing the long format multiple times?
