You would think that, with computers dominating every aspect of our lives, people would be aware that storage devices can retain information even after clicking "Empty Recycle Bin".

Not so, according to research by Finnish data removal specialist Blancco. The company purchased 159 random used drives on eBay in the US and Europe, and found that 42 per cent (or 67 devices) enabled anyone with basic IT literacy to access the data stored by their previous owners. A whopping 15 per cent contained personally identifiable information that could be used by cyber criminals.
