There are laws that require you to prevent unauthorized access to personal information. Computers do not last and have to be replaced. Before you send off the old one…wait! This is also true for copy machines as many have a hard drive built in. It is also true for mobile phones, PDA’s, USB drives, and other electronic storage devices.
Your information is still on the old hard drive. Deleting files and/or formatting the hard drive does NOT remove the information. In order to keep that information getting out you need to destroy the hard drive.
