To dispose of a laptop hard drive in the most secure way is to shred it. Even the best erasing machines leave data a hard drive. In fact, on Sept 16, 2016 the NBC Nightly News story “How Supposedly-Deleted Personal Data Can Come Back to Haunt You” discovered that 46% of personal computers and other used devices purchased online, still contained personal information belonging to the prior owners. The only way you can rest assured that all data is destroyed is with shredding of hard drives. It does no good if you protect your social security number and bank account numbers and credit card numbers if you are letting your hard drive be wiped. The possibility that there is still data on erased hard drives are too high.
