Ask the Doctor LogoI’d like a program that can safely and effectively clean my hard drive so that no deleted files can be recovered. Can you recommend something? I see a bunch of stuff out there but it’s for permanently deleting files, not for already-deleted files. And I don’t know which programs are clean—free of malware or other crap. It must be good enough that I can feel safe about giving an old PC to someone else and not worry about identity theft. Also: What would you recommend to minimize any data being stolen from a hard drive if your PC was stolen? I am presently using Splash ID to store my passwords and sensitive data but would feel better if the entire hard drive was protected.
