I have a windows 8 running laptop. I want to send my laptop to the service center as it got some technical issues.i have formatted my hard disk and erased everything as i want to make sure that the service center guys do not recover any of the files from my system using any recovery softwares. So for that i have filled my entire harddisk with some junk files so that there is no more of my deleted datas on my hard disk sector. Is this a foolproof method?
