I know I have posted a few questions about this in the past. I have now decided to dispose of 3 Windows 98/98SE desktop computers and monitors that are old and no longer used. I have nothing I consider national secrets, damaging personal info, or anything I would fear retrieval of by others. So I think extreme measures like smashing up with sledgehammers and throwing hard drives in ocean after burning and smashing them is unnecessary. I feel like simply copying the files and folder like My Documents to an external hard drive then formatting and wiping the drives clean would be enough, and maybe saving any program installs that I like and would work with later OS. It has been a long time since even turned these on but they do work as far as I know. Just outdated and have 3 laptops now with XP, 7, and 10. So do not ever use the desktops. I know there are postings of software to wipe clean the hard drives but am unfamiliar with these and how to use them. I was hoping someone could suggest some free programs that are easy to learn and use that would format the hard drive of anything someone would retrieve short of an FBI investigation. I think wiping it clean would do then call the township electronics disposal company that picks up discarded equipment and arrange pickup. If someone has any better ideas I would like to hear them also. Otherwise I need to know a simple program to erase hard drive on windows 98 or 98SE desktops after I copy and/or delete what I do not need on them but want to save. Probably no one would want to buy them or have them for free although they probably do work, for they are old and outdated and used a lot since 1998. Can anyone help me with some suggestions? If so I would appreciate reading whatever anyone might suggest. Thank you.
