FDISK WILL NOT repeat WILL NOT wipe the disk! It will only remove partitioning and format info.
There are "wipers", both freeware and commercial that will do the job. Wiping can be from a simple wipe to highly sophisticated ones depending on the info contained in the drive.
If you want to destroy the disk, then bake it in an oven after drilling a few holes thru' the victim!
I have a new computer and want to wipe the hard drive on the old one... Can someone tell me how to do that? I once used fdisk - but don't remember how to do it.
Is there a better way to insure my stuff is off before passing this dinosaur off to someone else?
