Most folks seem to think that if they format their hard drive, their data will be gone forever. Nothing can be further from the truth. There is a good reason the NSA and other agencies degauss and crush hard drives to destroy data. We have already covered hard drive crushers here in the past. The Datastroyer 102-DG Disk Erasing Wand Degausser is a portable device you can use to degauss 3-1/2″, 5-1/4″ or 8″ floppy disks and hard drives. It wipes them to a forensically irrevocable state.
The design is portable, which helps. These ship with a steel case, so you don’t have to worry about accidentally killing all your data. The Datastroyer 102-DG has a magnetic coercivity of 5000 Oe, so it is powerful and small. This could prove useful for businesses and security experts.
