The Mag EraSURE ME-P3M degausser from Security Engineered Machinery of Westboro, Massachusetts, completely and permanently removes confidential information from hard drives and other magnetic media. The manual unit complies with National Security Agency and Department of Defense degaussing requirements. In approximately 15 seconds, the unit quietly erases data from hard-disk drives with nominal coercivity ratings of up to 5300 Oe and magnetic tapes with nominal coercivity ratings of up to 2600 Oe. It accommodates floppy disks and most desktop and notebook hard drives, whether they are functioning or not. It also works for multiple tape formats. An array of permanent, rare-earth magnets enables the unit to completely erase data and timing information. Because it generates no heat, it can be used continuously and in tight spaces.
