Hey guys, I'm asking around regarding this for my friend who's laptop has now become a paperweight. I don't remember this information from my Dell Warranty certification. Unfortunately his father purchased the Dell laptop for him off of ebay approximately 6 months ago. He's never had a problem with it, no security was on it or anything. Recently he decided he was going to dabble with Windows 7 (against my judgment) and he wound up breaking his laptop and wanted me to reformat it. The day of having me come over to do so, he reported that he was getting the HDD security screen and needed a password. My first hunch was that someone had messed with his laptop, however he swears up and down that no one would have accessed his laptop, and no one has copped up to it. Since he isn't the original owner of the laptop, Dell will not assist him with the backdoor password. The part I can't remember: Will replacing the hard drive in effect remove the error? Or will the error persist? Can this be replaced by replacing the hard drive, and if so is there a specific kind of hard drive that needs to be purchased that would work with the laptop? As always, thanks guys!
