I was thinking about wiping my hard disk drives and wanted to know if this would in any way cause the drive to go kaphoot for future use. I don't intend on selling off my pc but the feeling of having the hdd as good as new makes me very curious. Since i already have maybe three past virus infection with the hdd it sort of make me turn this way. So what do guys have to say about my confusion if i should indeed go at it or not? And will this process create any installation problem after i complete doing it all? Will this erase the bios as well?
