Securely Erasing USB Devices

These instructions are for using Eraser software to securely erase data from removable storage devices such as flash drives, USB sticks, thumb drives, or external hard drives. The primary resource for disposing of a computer belonging to the University of Notre Dame is through the ND Surplus process. If you need to dispose of an entire computer or wipe a machine prior to re-use, you should erase the hard drive contents using DBAN.

WARNING: Eraser is a powerful tool that will permanently remove data. This process is not reversible.

Eraser software is designed for use on Windows systems only. To use Eraser, follow these steps:
