A recent study by Kroll Ontrack looked at the prevalence of ghost data – data that was thought to be dead but unexpectedly came back to life – on secondhand devices and technologies. The results? Haunting.

• Almost 50% of the hard drives contained residual data

• Thousands of leftover emails, call logs, texts, photos, and videos were retrieved from 35% of the mobile devices

• 57% of the mobile devices and 75% of the hard drives had unsuccessful deletion attempts before their sale
