Don't want to go into how it happened here. Suffice it to say that I've tried what you suggest with a work copy of XP just to see if that would reformat it, then I would go back to the Recovery CD's that came with my computer and reformat from there (the legal way). Even trying it this way it only goes up to a point , but when it tries to load windows the error message comes up that the hard drives are missing. Do I have to get a new hard drive to solve this? There were no windows disk that came with the computer (it is a Sony Vaio) that had Windows ME (I know, I know I know)... Just need some practical advice on whether I should just give up and buy a new hard drive, new computer, etc....
