We talk a lot about shredding confidential documents and other paperwork, but do you ever think about the other things in your life that contain sensitive information? In the modern age we tend to keep a lot of information on our phones and computers, but give little thought to what data stays on the device after a ‘system reset’. Amazingly, it’s much more data than you would think. That’s why you should always remove your hard drive before you sell your old computer or laptop.
Why Shred Your Old Hard Drives?
Shredding a hard drive is the only way to ensure that the data on it can never be retrieved (short of investing in a very large magnet). Many people think that if you format your hard drive, you are erasing the data from it. This isn’t the case – as this only clears the re-writable areas. There are still many areas of your hard drive that formatting doesn’t cover. To illustrate this, a group of students from MIT bought 258 used, formatted hard drives on eBay. Using some basic, freely available forensic software they were able to recover over 5000 credit and debit card numbers, medical records, social security numbers and other highly sensitive information. Running a magnet over your hard drive won’t wipe it clean either, as you would need a magnet with a pull force of at least 450 pounds to have any effect. But with a pull force like that you would only be successful because you’d have destroyed everything else in the room as well.
How Does It Work?

If you’ve been stockpiling old computers and laptops instead of getting rid of them, hard drive shredding provides the perfect solution for you. Shredding your hard drive protects your business against digital data theft in the most realistic way possible – by completely destroying the data. Computers and laptops without hard drives can still be sold on to recoup costs or make a profit, but with the knowledge that your data is safe. If you’re not sure how to remove the hard drive from your computer, check out our guide here.
