I have some external 2.5 and 3.5 form factor hard drives. I have reformatted every drive and everything is erased. I understand someone can go in and use software to retrieve the deleted files.
My question is how do I make the drives secure before selling them? Any suggestions would be appreciated.
I looked up secure wipe on the net and ran across this web site where you can download a program called Darik's Boot And Nuke, here is the site web address:http://www.dban.org/.
There is also some good information about wiping hard drives on this web site.http://www.zdnet.com/blog/storage/how-to-really-erase-a-hard-drive/129
