Format and reload.
Run a pass of killdisk/dban format and reload.
Best. (high paranoia level)
Remove the HD and destroy it.
It seems there is no good way to 100% erase a HD.
I am (hopefully) selling my laptop and I would like to format my hard drive (for safety and privacy reasons) I am selling the laptop with vista and I was wondering if formatting the hard drive would delete the operating system. The laptop did not originally come with vista but I have the installation disk. I would not mind installing it again but I have already used the product key if it makes a difference.
Please could you help?
ps. the laptop will be on eBay if you are interested
