Out with the Old (Computer): How to Do It Safely
Since computers often hold personal and financial information, the most important thing you can do is ensure that its hard drive doesn’t become a treasure chest for identity thieves.
For starters, you should understand how your hard drive works. When you save a file, especially a large one, it is scattered around the hard drive in bits and pieces. When you open a file, the hard drive gathers the bits and pieces and reconstructs them. And when you delete a file, the links to reconstruct the file disappear.
But the bits and pieces of the deleted file stay on your computer until they’re overwritten, and they can be retrieved with a data recovery program. To remove data from a hard drive permanently, the hard drive on your discarded computer needs to be wiped clean.
