I want to completely and securely wipe my laptop’s HDD.
I want the HDD to have nothing retrievable on it.
obviously I would need a program which will run from floppy on start-up.
Most important - it need to be free!
I’d suggest Darik’s Boot and Nuke (Hard Drive Disk Wipe) I’ve used it before selling a laptop, It gives options to wipe using certain standards e.g. American Department of Defence.
