How to Properly Erase Your Data Before Reselling or Discarding Hardware

Deleting a file, emptying the recycle bin or running a quick format only makes the index that points to your data disappear: the data itself stays physically present, and a simple free tool is often enough to restore it. Everything a lab knows how to recover, a curious buyer can recover too. This guide details, medium by medium, how to truly erase your data before reselling or discarding a computer, phone, drive or USB stick: overwriting every sector, factory reset on an encrypted phone, a degausser for tapes, and physical destruction as a last resort. You will see why a discarded medium is never anonymous, how to destroy a chip without piercing the battery, why BitLocker encryption does not remove the need to destroy, and what Switzerland's nLPD and the GDPR require of businesses.
