Many of EFF’s recommendations involve copying data onto an external device and then removing it from the device you’ll be carrying across the border. When doing this, you will want to make sure that the data you delete is actually gone. Simply pressing the ‘delete’ key or emptying the desktop waste basket makes the data disappear, but it doesn’t necessarily remove the data in question from a device. A competent forensics examiner will be able to recover files that were merely deleted, unless you securely delete files using a data destruction tool that removes and overwrites the data in memory.
